Cool I have a Briggs golden boy and it sat for about 5 years and I got it out and took the air filter off and changed the spark plug and it started right up
Pod cast subscription engaged 🤘 courtesy of wanting to know Briggs & Stratton voodoo knowledge!! We own a hardware store and small engine shop that's been around since the 40s the oil we use is made by a company called kinetix High performance oil it has zddp in it already and it's formulated for Air Cold engines I run it in my air-cooled VW engine since I build and all small equipment with no problems and it's cheap!!!
They should build like a stupidly overpowered one, stroker, big bore, just something unordianry that you don't commonly see on a brigs 5 horse. Maybe some nitrous or forced induction, that would be sick 🤭
Built lots of 5hp Briggs over the years, from home made hop ups to running stock, super stock and limited modified in WKA races. They are still my favorite small engine.
I'm so happy to see you guys working on another Briggs! As I write this, I have 3 of my Briggs and Stratton's sitting next to me! Isaac, the newer coil swap you speak of was called the "magnetron" ignition, and engines started coming with them in 1982. Somewhere on that engine shroud (probably one of the flat sides) should be a model number, if it starts with 10, its a 4 HP, and if it starts with 13, then its a 5 HP! It's the cubic inches. The first two digits of the serial number indicates the year of the engine. As for what to do with the output shaft, I think you guys should pull the side cover and remove the plastic governor gear and internal and external governor arm of the engine at the same time as a crank swap! A side cover bolt with thread right through to fill the hole. Then set up the throttle cable to come up between the fuel tank and the shroud and have it take the place of the governor rod. That's an easy way to use the factory carb and fuel tank, and keep the engine safe from blowing the governor gear! Also, I am here to say that I care for the flatheads stronger than I do these Honda clones, and I'm ready to hear all your old stories from back in the day!
As soon as he said "it's like that stuff" I was 100% sure he was on about that florist stuff lol. Amount of times I pushed my finger into that stuff as a kid 😂😂
Thats crazy I just pulled my 1970's Montgomery ward mini bike outta storage for the last 20 years. It has the same exact motor on it, all it took was a new spark plug and she fired right up. It's not the original motor, came out of a snow blower. The 5hp briggs takes a beating and just keeps on going!! Love the channel!!
hey John!!! just passed through NC last Saturday on our way to Myrtle Beach, SC... Please tell Ike that based on his recommendation, we took the kids to BoJangles for lunch this afternoon!!! LOL!!! We don’t have that chain up in Massachusetts! We also spent the day at Broadway Grand Prix Karts! They ve got a TON of Karts and Tracks! GOOD FUN! -Glenn from Mass
Never doubted it would run! Old School Briggs & Strattons were bullet proof! That Zinc Additive will save all those older engines. Can't hurt the newer ones either.
Dude I am a flat head forever loyalist I don't think I've ever been more interested in the episode than I have now I can't wait to gain some of your knowledge I really hope you can get people interested in them more and maybe go power sports can make more parts available I have a methanol mini bike 5 hp briggs 30 over , big valves ,porting lightend camshaft mikuni side draft carburetor two-stage exhaust it goes 70mph
I like the thumbnail where Ike is popping up into the attic, and he sees the generator and is like, "There you are." A wild 5-horse Briggs & Stratton appears!
Thats cool 😎. I have the exact same one. It was my father in laws and it's been im my addick for years. Yall done got me working on it, lol. I'm going to find out if the generator works. Can't wait to see how well it works on that minibike. Keep em coming guys, love yalls work
awesome cant wait for this one to be up and running ..when you got the 5 bikes Isaac this is the one that called to me .so its going to be my FAV out them all :)
Great find, and work. That thing should be a really good piece. I would not be surprised if it has a steel sleave, a heavier crank, and now a updated ignition. I'd put a 22mm round slide on it, a pipe and put it in a minibike!!! Again great work guys!
A few things 1. That's a Grand Prix mini bike. Taiwanese made and sold under a lot of different names, including Deltek 2. The engine size is stamped on the side of the tins above the gas tank. The first two digits should tell you the displacement. You can look that up to determine the power rating. 3. Awesome video. Keep 'em coming!
The flywheel key is aluminum so it shears easy enough that if the crank takes a shock load, it doesn't split the flywheel, or bend the crank. I have done all the mods you mentioned in this video to my Kart engines in the past. Literally all the key does is set the timing relative to the crankshaft. I never use a key in my flatheads. I throw the key over my shoulder, and turn the flywheel clockwise the width of the keyway to advance the timing for more top end power and more rpms. Shaving the head, advance the timing, smaller flywheel, and stuff a 6hp I/C crank in a 5hp block to get just a bit more stroke out of them, also the 6hp I/C cam. Has a bit different of a grind to it than a 5hp cam does. Also, make a custom tuned header by painting an 18" long stick of black iron pipe really thick with cheap paint, where you see the paint bubbling after it has run for a while, cut it off. Bam. "Tuned" header. All on the super cheap. You could also use one of the aluminum flywheel that has like 6 magnets in it with advanced timing. It will have to idle pretty high, but will rev REALLY REALLY REALLY REALLY high, REALLY REALLY REALLY REALLY fast. And I have never seen or had one personally explode from too many rod. Also, if you add a canted engine mount under that engine, it will hold more oil.
Damn! That looks familiar. Takes me back to teen years and the tiller we used to have. It had front tines and that was the drive. We'd start it up and let the tines pull it from the garage out to the garden. Might've been the same engine model too.
Take your starter clutch apart and polish the crankshaft extension with scotchbrite. Clean the starter housing and balls and just LIGHTLY mist with a quick shot of wd-40. Reassemble, and add a few drops of 3in1 oil to the hole in the top of the clutch housing. Add a little Oil into the blower housing to oil the spring and pull a few times to distrubute the oil. Reassemble and you should be good
Ike you are amazing. Can't believe you guys got that thing running. Love all you guys do keep up the good content I look forward to every video. Can't wait to see old blue ripping down straight away at the cars and Camera headquarters
Me being a huge Briggs fan and in my younger days never having enough cash for a newer engine I watched this episode having flashbacks of the good old days when the Briggs never let me down. Can’t beat the Honda clones though there’s just to much aftermarket support to squeeze every little hp you can out of them. Used to almost get a Briggs for free back then though
Crime doesn't pay!!! Cutting corners is just being lazy!! Do it right the first time, or don't bother. Good work ethics always prevails!! You guys already know this!! I know you had the coil on hand, and you figured why not. Thanks for sharing fellas!!
I just recently got a go kart with a 5hp briggs. I've worked on plenty of briggs before but never a 5 horse and I am just astounded by how good it sounds even with stock exhaust every time I start it.
When I was racing go-karts in the 80's with my dad, a smear of valve grinding compound on the crankshaft taper held the flywheel on tight. Set the timing with a degree wheel. We never used a key.
Thanks John. I needed yet, another reason to feel old. "THAT'S the governor?!?" Yep, it used to be stupid simple to remove the governor from our mini bike/go kart engines, LOL. AND NEVER had one blow up because we removed it either. They were built TOUGH.
To anyone curious about generator RPM: Direct drive, AC generators typically always run at 3600 RPM. That is because 3600 RPM is 60 revolutions per second. This coincides with 60HZ AC power, which is also 60 cycles/second.
Man I might just drive the 3 hours to Texas motor speedway just to meet you guys. Been watching your channel since you guys were small and have really enjoyed your journey over that last few years! Can’t wait to see what awesome projects you guys tackle in the future!
I love these style videos. I watch mustie1's hour plus long videos until i crash. These videos are so interesting to me watching people take vintage motors and give them another chance at life.
I know i have mentioned several different suggestions for ideas on builds but i just found one that sounds really cool. You guys should try taking a self propelled push mower and turn it into a riding go kart. I guess you replace the blade with a pulley and this will power the self propelled part faster. build a chair over top the motor with a steering system in front.
Gen tech here. We have maintenance agreements with customers if they choose where we come out and maintain services on generators annually and semi annual inspections if they choose. But yes a lot get neglected
That "Briggs Mod by Ike" sounds pretty good. I'd like my son and grandson to watch and learn a few tricks. We have all kinds of small engines here and come across plenty others.
For classic car applications, the guys at Shell often recommend Rotella, and although it’s thought of as a diesel engine oil, its high-zinc formulation that’s made to fight scuffing on metal-to-metal contact is just what older engines need. So make sure the oil you select for your classic engine is from a quality brand and that it has plenty of ZDDP. You don’t have to guess though, you can get a recommendation from Shell by calling 1-800-BEST-OIL.
I love the idea of repurposing engines like that, but I'd still love to see a kind of throw back repurpose, with a twist, like pull a Briggs vtwin mower engine and do a conversion to a horizontal shaft, slap it on a kart
I just did that with the same (vertical) engine on a tiller, but I used the plastic clip on to the coil condenser (original points delete ). I couldn’t find the new magneto replacement.
Reminds me of mine from 70s, runs all same part except spark plug, but recently overheated and gaskets leaking or something else, gotta take it apart, but before that it ran for months, cleaned gas tank, carb, boom ready to go.
You guys need to use a strimmer and a lawnmower diff or something and build a front engine, rear wheel drive, shaft driven go kart. That would be a great cruiser. Also, it would be awesome to see that generator rebuilt and put on an engine for mini mayhem
You have my call for more of these. I have a gocart weighing about 50 lbs custom made in the 60s with a 3.5 horse 1 wheel peel and a singular custom made body panel. Has a door hing break and was made with a few car batteries as welders. Bout 12 feet of angle iron and 5 feet of 1/4 inch steel rod is the whole chassis with some sheet metal seat an wheel. When I say seat I mean platform and when I say wheel I mean square. This thing has a cold beer and a story to tell. Being my father's and my grandfather's before mine
Looks alot like the old Sears Roebuck mini bike like my Grandpappy used to have. BTW, it required a custom exhaust and a fuel tank relocation. Love this channel!!
This is an old engine, it has the air vane governor. I'm betting its a 3 or 4 hp not the more common 5 hp you are thinking about. In the 80s and 90s before briggs gave everybody the finger the raptor and animal engines were beasts.
