Will The Worlds Fastest Airplane Finally Start? 

Hey, hats off to the guy in the last video comments who said the exact same thing about the harness wires probably being the issue. YOU WERE RIGHT BRO!

actually loving this channel. as someone whos into cars and bikes even im learning a ton. thank you and keep it up

Darn, I was betting it was going to start right up! What could possibly go wrong? Back in the 70’s I was racing. We put a high yield ignition on my barracuda. Ran like K-rap. Changed the plug wires out for Shielded aviation/racing wires. Wow it sung! So I was hopeful. It was doing the same thing. Spark was jumping the wires. “Can I get a CLEAR PROP!”

You're the one channel I can confidently LIKE before I even see the video. Thanks for giving us all the opportunity to experience a little bit of your journey in aviation. Everyone on your channel is awesome! Keep it up. Stay safe!

You need to get some good spark plugs if you want to keep that thing running at peak power. I hope you put clamps on that vacuum hose, it's not like you can just pull over to plug it back in if it comes off. I hope it is sturdy enough not to collapse either from the vacuum.

I found out about spark plug wires long ago, trying to improve an original Mustang with "better" wires. Found out the OEM factory ford wires beat all the expensive crap in the speed shops. Aged better too. Spark plug gap? I had a car where the drivers manual and full shop manual carried one number--but the pregapped OEM replacement plugs were always at a consistent different figure. At $50/plug, I hope they at least are platinum tipped plugs!

Just a little detail on your bottom plugs. The reason these types of plugs are used on aircraft electronic ignition systems is the ease of obtaining the larger gap that can be used with the higher energy spark of the EI (which you did talk about). Regular massive electrode aircraft plugs would be difficult (if possible) to achieve the .035 or greater gap usable with an EI system. Electroair for example, specifically calls out the BY style plugs you had in the bottom with a gap of around .036. I run the same ones on my RV6 with Electroair ignition. Many of the experimental electronic ignition systems folks recommend regular auto plugs with similar larger gaps. For checking gap I use a piece of .032 safety wire from my tool box and set the plugs up for a easy/slightly loose fit of the safety wire gauge.

Make sure you have it in the “O N”position!! Haha heard that from a crew chief who just worked on an aircraft at Elmendorf AFB. Cracked me up!!

Regaping plugs is not always as easy as it would seem. I have seen used plugs (not machine cleaned) that are cracked; but not on visual inspection. If it was me, I would buy new plugs that are professionally gapped. But that’s just me. I enjoy all your videos. You are my kind of crazy.

Nice project, keep going. W8 what about adding some winglets to reduce induced drag or add/remove something else in this manner or perhaps reduce some weight, it might help too.

We always used a sand/glass blasting machine on our plugs for annuals. It works and saves a ton for the owners in replacing spark plugs. :)

love all of it on this channel, but I got to tell you, I keep watching the latest fly-ins for Oshkosh hoping to see that silver 310. are you going?

Perfectly normal to see BY plugs in the lower cylinder spark plug location they help prevent mag drops due to spark plug fowling with lead. That's why you saw lead in the plug - leave em there 👍

Spend Jimmy spend! We love to see it. The more it costs the happier it makes us viewers. Thanks for the videos, great stuff.

Thought your at Oshkosh ... i was getting ready today to head to EEA and meet you....

Jimmy, I am so excited to see you get Cameron going even faster. Just be careful getting used to the extra speed. I saw the Apache on Craigslist for sale. Hope someone gets it and makes it even better. God bless!

Jimmy is so hyper he makes coffee nervous 😆

I work with lasers at about 10,000V. They arc through just about anything if you damage the original insulator.

Batteries out gas hydrogen and I have seen several blow up doing things like this. NO SPARKS near the battery.... And it's not just when it's charging!

16:30 I guess you've never seen a battery blow up from a nearby spark? I did it once with a truck battery.

Always good content. Personally, I enjoy a little goofiness. So many channels take their own selves too serious for my taste. I also despise reality scripted drama. Jimmy is far closer to my style of mechanics. All business when flying and prepping the plane but if you can't have fun then what's the point in living.

Just got to the end of vid. Great job improvising a test for the mags!! Looks like not getting power to them in the plane. Can't wait to see the rest!

Did you make it to Oshkosh, jimmy?

Your quest for more power, especially in the experimental realm of things, can potentially prove most detrimental, to put it nicely. Use the upmost of caution!

While this 17 mins of content is fantastic…. I crave more Jimmy’s World! 😀. Keep capturing that footage!

Just started watching more of your videos I really enjoy them and I totally dig your humor

Congrats Jimmy, on almost getting the Plane to start after u did alot of work on her. lv ur crazy way of doing stuff.

Hey Jimmy, really enjoy your videos. The engine really does make those BTU's, but the magneto's should make those 'Lightning VOLTS'.

Keep at it Jimmy it will run. Love your videos

HA, I was saying the same thing about your spark plug wires, I did something similar to an old sports car I had in 1976. Upgrade the ignition to a "Capacitive DIscharge" with a heathkit. It blew the high voltage through the stock plug wires. Upgraded those and double the spark plug gap. Smooth, more power and better gas mileage.

Back in the early days of been a mechanic nobody told me the jaguar battery had been on charge over night ,took some jump leads thinking it might need some help in starting it and BANG !!! the battery blew up in my face just one small spark did it,luckily I was ok just had someone who knew what to do helping me. Jimmy !!! Carry on the great content cheers

I love this channel! Thank you for the fun and inspiring content😁🙏🏼

Go to Harbor Freight and buy small beed blaster, you can clean Spark Plugs like new use smallest glass bead and small Air Compressor. Keep little more distance and max 80psi.it’s safe for cleaning spark plugs.

Save the 310 that had a gear failure at oshkosh!! You need to do something with the rest of mighty mouse. Might as well use it to save another 310

You should get some griplock ties instead of those cheap zip ties. Also a lightspeed ignition would be the way to go. For you to get to 250 you're going to have to cut drag wherever possible. Cooling drag is probably the first thing I'd go after.

I believe the BTU defibulator will cause the atomizer of the dinosaur juice to dribble out the explosion exit with alarming lack of clarity.

The bottom plugs are protruding electrodes, common to use on bottom so they do not foul as easy, some people also run fine wire on bottom only for the same purpose. Rem38Es or something on top and Rem37bys on bottom probably. Also saw you taxi in 310EB yesterday on Oshkosh live cams, she is shiny.

I know it doesn't but I'm just picturing a big boom off screen when you start it. Jimmy turns the key and 💥 joins the space program💥

Add a Sealed plenum cooling baffling, and an MT prop.

Like the old Serial Cowboy Movies when I was a kid...the show gets you on the edge of the seat and then... To Be Continued

Spark jumping to the case or bad ground or the wires ? Can’t wait to see

Thanks Jimmy. Things keep happening for you but you are learning and we are learning along side you.

@16:40, creating spark around that battery could prove to be very interesting. Experience has shown me what can happen, a friend had a battery blowup from even a tiny spark, put a wrench into the hood of a C-10.

Put E-Mags on the RV6A I built and using auto plugs at $2.50 instead of aero plugs at $20.00 a plug. O320 starts and runs great.

Always entertaining. I tune in for all the technical terms.....

Never gapped a plane plug, but the hole in the guage is for spreading the gap without putting pressure on the center electrode.

While they're on the plane, can you pull the harness off, put something ground by the mag outputs and test them. Just thinking those harnesses might be the issue.

I can't help but think that if the harness is that big of an issue, the sales rep maybe should have asked that question before selling/shipping the magnetos to you. Strange.

It will start and you can go have fun and go on to the next thing.

did you make oshkosh? i didnt but will be there next year!!

So it was breaking down under load glad you found out.

You need to ante up for some angle valve cylinders to for more BTUs

Never saw that one coming! Looks like you get your luck from the same shop as me!

I love this channel! I love cars space and aviation a lot and these are always interesting!

I have to admit Jimmy, you're making me hesitant to do a mag upgrade on my little lancair.

Hey Jimmy was watching an EAA video and saw you arriving at Oshkosh with the Silver Bullet pretty cool

Question, are the harnesses not the same type for each Mag?, if they are the same why did it only effect one side?

you should send the heads to lycon up in visalia california, those guys do magic for performance

I have not watched an episode for some time. The moment you started all I could think was nice PRON stache.

I'm sure you'll get it Jimmy. I have faith. Enjoy Oshkosh!

Hi Jimmy, really appreciate your videos. I always learn something new.

Jimmy, this is how a barn find is made: 1) Buy parts, 2) install parts, 3) flood engine, 4) Age plane and parts for 15 years--preferably outside in bad weather.

Please use die-electric grease for plunge and magneto it helps prevents corrosion.

Nice project mate! You should try to make it as fast as possible! Cheers from Germany!

Not broken, just another challenge, all part of the fun...Right Jimmy? Keep on rockin!!

The hole in your gap tool is to bend the spark plug tabs. if you pry on the center electrode you have a possibility of cracking the center porcelain,

I like the way you refer to B T Us British Thermal Units

I'm guessing the electronic mags need a high current power source using a couple relays (fuse protected) connected to the battery, and the relays powered by the ignition switch...??

Fully clean those sparking plugs while they’re out. Nasty

gotta make the tree huggers and polar bear savers happy lol i love jimmy

I've seen that before on the lower plugs - trying to give the plug a chance to not fill up and keep it from oil fouling. If they knew it was oil fouling, this would be a kind of band-aid fix. Hopefully you're not passing too much oil past the rings.

Jimmy I can’t find the video where you fixed the ignition problem What did you do to fix the wires and electronic ignition problem Thanks

Was at EAA on Tuesday. Could not find the shiny 310. Did you you make it to Oshkosh or not?

Like Tim the Toolman, I predict by adding more power it will break some where else than the ignition.

Polished ports and polished plane skins are needed for areo dynamics, planes and ported intake and exhaust in an engine...slick 6000 grit polishing sandpapers and others are used for some peoples planes and boats, cars for extra speed because of a need for speed with less drag...blessings...m

For you advance timing tubing, what like of pressure is being made. Does the yellow tubing need s clamp to insure it doesn't come off.

Like these videos! Question though, when you got the new mags, I assume you ordered them, they didn't tell you you needed a different wearing harness for them? That just seems like really poor customer service. And you are wearing their shirt!?! I don't know, I would think when you bought the new mags they would have been an "* You need the new wiring harness"

My wife worked at Lance air in Bend Oregon for several years I hope your plane flies again.

I think investing in a spark plug cleaner, Which uses compressed air and some type of abrasive bead to clean the spark plug immaculately and doesn’t harm the surface, Would probably increase the life of the plug and the firing efficiency I believe when I had one I bought it through snap on

Jimmy - I've gotta admit, that thing is really really quiet!!!!! I had neighbor who bought new Jet-Drive boat, that was supposed to be fastest on lake, lost $500 losing every wager, 7 trips out to Marine Dealer, lost another $1200 being loser, so said I'd fix it, but it would cost 'em case of Corrs. Motar was Turbo Ford 460, and Gawd it was purtty!! Took glance at wiring, and spark initiator wires doin' it side-by-side held there by Ford Official genuine black plastic hoops, as this sucker was factory man!! At RPM, this Super Boat's Motar was cross-firin' it's sparkalotors to beat the band to just go 112MPH = Piss Pore!! I snipped the hoops, freed the wires, ran them perpendicular, which made it look like a fazed out lady of the night, but when fired up, it ran like a rapid ape!! We got our speed equipment out, 2 pair of swim trunks & 2 pair of hold-me-tight sunglasses, & neighbor drove (Piloted) us 148MPH! Neighbor made his lost bets go away about 12 fold, AND I GOT MY BEER!! Sometimes ya just gotta jump thru the hoops to make your motar very noisy...good luck with the plane Jimmy!!!

Jimmy! Please! PLEASE fix the overhead blinds in Cameron. The captain side is falling out of its sleeve! Thanks -OCD fans!

HEADS UP WATCH OUT FOR FLAMES........CUZ WHEN THE SMOKE ESCAPES ... SHE NO GO..learned from service techs in electronics and aviation control black boxes...best wishes.. GOOD LUCK LOVE YOUR SHOW

Hey Jimmy. I juat love your videos, and just looking forward to new ones from you. I don't know what the price is for an engine, but have you thought about replacing the engine with a Turbo-Prop???

rescue rebuild got a dry ice blaster.If you want to super clean your engines maybe stop by where he does his work sometime.

The image to Tim the Taylor was amusing to me. I wonder how many of us appreciates that reference?

LOL love the Bench Test set up. Thanks for sharing. Best Wishes & Blessings. Keith Noneya

Since when do mags put out BTU's?

Really thought you were going to crack the problem this time Jimmy. I think Cameron is quite happy to "pootle" along at 189kts.

OMG come on Cameron we want more btu's 😃 .. big thumbs up jimmy ... #SaveThe310

I may be wrong but doesn't the spark plug gap need to be measured between the center electrode and each ground electrode instead of between the two ground electrodes?

That would be interesting to run the old plug wire harness in the dark to see where the spark is going.

Amazing channel. Keep up the good work.

Work montage music remindes me of the old Mastermilo days.

Dangerous Freedom is Expensive.. But, it is OH so worth it!! 👍🤗🥳 I have found that, MOST of the time, I only have to spend the big bucks once. After that, it's a matter of changing spark plugs and gapping them often... I always keep two or three spare sets, and have sets to swap out. Saves time.

You converted the reliable magneto ignition system which make there own power to the unreliable electronic ignition that depends on battery power. And no back up alternator or battery. Brilliant Jimmy 🤔

Power leads to the mag switch, it's possible the switch is bad. Separate leads for the starter function lets the starter engage, but if the switch is bad it's cutting the flow of juice out of the mags by opening the circuit. Simple to check with an ohm meter.

Mags shut off on a ground circuit. Are you sure your ignition switch is good? The ignition circuit isn't pinched somewhere to ground between the switch and mags?

Hope you show videos of Oshkosh soon, well I hope you made it to Oshkosh. Another great video.

The Plugs need to be tested on a spark plug tester to see if they are firing under pressure. Clean them and blow them out with compress air and use champion spark lube on the threads and new gaskets.
