I picked up this rockwell snowmobile engine a property that was getting cleared for demo, along with a bunch of basket case parts, lets see if we can save it.
Mustie is the most epic trash picker/yard sale known to man..the early bird gets the prize..always amazing what strays he brings home as we enviously watch ..
The ILO-Company was founded 1911 in Hamburg, Germany. Initially they produced track tamping machines, later two-stroke engines for small cars, mopeds and motorcycles. In 1959 ILO was taken over by Rockwell and produced engines for snowmobiles for the American market. In 1977 the company was sold to Tecumseh. In 1990 the company was closed down because the competition was too big.
Ah, wen man hier alles findet! Richtig beschrieben, das deutsche Werk war in Pinneberg und mit dessen Schließung gings leider auch mit Tecumseh Europa bergab, bis die 2007 selber dichtgemacht haben. Unvergessen auch die die guten Jlo Standmotoren und Rasenmähermotoren, unter anderem der RM 77, welcher auch auf Wolf Motodux Rasenmähern in den 70er Jahen zu finden war.
@@Look_What_You_Did Nonsense, I live near where the ILO factory used to be and have had a few mopeds with an ILO engine myself. I have been working with small two-stroke mopeds for decades and know the history of some German manufacturers quite well.
I have watched many of the small engine mechanics on YT and for some reason Mustie1 is the only one I really enjoy, I have watched him for years and his exuberance and excitement is infectious he is by far the most competent and knowledgeable guy I have watched he is informative educational and always explains in layman's terms what he is doing and why.
My favorite part is how Mustie can just laugh every time something he made (like the bendix retainer) just blows apart and he's like "welp, I guess I'll make a better one..."
I’ve been with this guys since he had around 10k subs. I would watch his videos every night to fall asleep haha. It’s amazing he has been able to make it this far doing something he loves to do.
@@matthewwolfe7962 I'd have to go back and look at his videos. I might be able to tell which one was the first I watched. I do know I went back to watch his older custom bicycle builds!
That's a JLO engine (called Jello in Quebec when they were in snowmobiles). They were used in Moto Ski's & other manufacturers. Scorpion also used them & ended up building them in Minnesota I believe. When Scorpion closed down, a group of employees got together & purchased the engine tooling & rights. The engine was renamed "Cuyuna" & electronic ignition was added, along with Mikuni carbs. They were sold as Ultra Light aircraft engines in the 80's. I was involved in the development of prototype snowmobiles for the Inuit in northern Canada in Montreal in the late 80's & we used these engines, however it was the 428 cc model, 35hp. They also built a one cylinder version. The upgrades of electronic ignition & mikuni carburation was a big upgrade. The company may still exist.
Originally it's pronounced "Eelo", for some weird reason the Germans often used an uppercase J instead of an I, quite confusing. According to Wikipedia, ilo is an Esperanto word and means tool.
@@davidelliott5843 I'm a native speaker of German and can tell you it's pretty much impossible to pronounce. As I said, it's a weird spelling quirk for I and then it's pronounced "Eelo". Have a look at the Wikipedia article, it shows the exact same logo with the J but everywhere else it's spelled ILO, complete with the Esperanto explanation. I'm sure Rockwell didn't buy two different German engine manufacturers with almost identical names.
Mustie could be a top fuel crew chief. The engine fires and I thought he was getting away and instead he's going for the gas bottle to keep it going. Love it!
These were used quite a bit in the early 1970s. We had versions on Moto ski and Scorpion machines, and I think they were used on Massey Ferguson Ski Whiz as well. They were made in 400 and 440 cc versions too. If I remember correctly one of ours had a Walbro carb and the other a Tillitson (not spelled right) HD. The 400 I rebuilt when I was in trade school in 1979. tough engines.
Hi Mustie I’d just like to comment on what you said at the end of this weekend’s amazing meeting with you… we dont even care if you fail to get a project to run or not we just enjoy spending our Sundays with you my friend. Hope you and your dear wife are well and until next Sunday afternoon take care of each other sir..
I was 11 when that paper was printed and visited New Hampshire for the first time the summer of '81. My great Grandma and great Aunt lived near East Andover.
What an interesting engine. It seems strong too. It's the best thing about Sunday when mustie1 posts a new video. Lucky you were able to buy a carb kit, I'm really looking forward to the next one. Have a fantastic day from Per Lidberg Sweden
Love it when that engine fired off. Hopefully that kit will let you rebuild the carb and get that puppy running again. That Snow Pony looks like a wild ride for sure.
It's quite likely because snow mobile engines were Ilo's top seller throughout the second half of the 60s until the Japanese pushed into the marked with aggressive prices and killed some of their competitors.
You never cease to amaze me with your knowledge and expertise in bringing old engines (that most people would have scrapped) back to life- and then repurposing them in a different machine. Sundays now consist of me waiting for the notification bell to ring, that Mustie1 has just posted a new video. Then watching with amazement at your skills and technical problem solving. Thank you.
Great video as ever. Love listening to your commentary as you work on various bits of kit. As a blind person, I appreciate it. Always wanted to be a mechanic before I went blind. Really interesting.
In the Ski Whiz snowmobile these engines would seize a little unless the weather was extremely cold, shut it off and wait a while and they would free up and restart. people would try different heat range plugs to attempt to stop the seizing but I don't remember this approach being very successful.
I keep a magnet in the shop and have lucked out numerous times when metal parts have gone missing, by dragging it in the vicinity. Also turning off the lights and using a flashlight at ground level really helps when finding parts that have jumped off the bench.
I remember being of pre-moped age (15) in Sweden my Granddad had 3 Monark 2-speed(gearshift built into the handlebar) Pedalpushed mopeds with ILO-engines on them, had a blast going round and round on the lawn behind their house and into the woods.
Mustie1, IT'S ALIVE!!! Ur Creatinity, Sustainability, Effectively, and engineering to get the motor to run is off the charts.. I thought it came with two CARB'S
JLO Rockwell engines wer in some early 70’s Arctic Cats. They were some vapor locking specialists. Nail the throttle and listen to the engine sucking wind and moaning and barely able to pull itself along. They might have worked well somewhere but up north in Ontario well they sucked, a lot of air and just stumbled around while your buddy’s on Ski Doo’s just rolled you.
The intro gave me a bit of deja vu, That mother and son sounds exactly like two my family knows. Old lady is halfway to 110 and despite her age its amazing that she moves around fine(with a walker) and her mind is still there, she was even still cooking regularly until a few years ago when her son convinced her to rest, much to her protest. They also live out on a simple but nice shaded farm property at the end of a loooong dead end road, even has a collapsing shed like you described. If you didnt live all the way in new england id be seriously wondering whether its the same people i know that you got the engine from.
We Agree Mr. MUSTIE has the best Laugh,and Cool stories when he Played around the sand pit.We love the stories with your Friends.Wondering if you have heard from an old Friend from way Back. Thank You sir.Makes my Day.Every Sunday.Hope you are Feeling Better.CHEERS
Your extensive experience involved in your hunches is inspiring. You've helped me tackle small engines and understanding carburetors. Your reductive assessment is something I've applied. Helps me to know what my problems are even if I cant fix it. I believe your about 98% in successful rehabbing of old engines.
JLO engines are/were made in Germany. During the early snowmobile explosion years JLO, Sachs and Hitrh were the prominent engines. Rockwell being a large company wanted into that business and they bought shares of JLO and private labeled the engines as such. Eventually the Japanese manufacturers made a better product than the JLO dinosaurs and they faded from the market.
Thanks for all the great entertainment Mustie. Been watching for many years and enjoy it greatly. There's a repair code my AT&T tech brother used when something they were messing with started working, like this engine's ignition - "Cleared while testing". Feel free to use that one. It happens, although not often enough. Cheers!
We had a 71 panther with a 340 JLO, that thing screamed, literally, had high pitch whine you could hear quarter mile down the road, tons of power too...💥
I've been a regular viewer for years and love your work. When I'm working on petrol engines to check spark I have an insulated wire lead about two feet long with a medium sized alligator clip each end, one goes to ground the other goes to HT terminal on plug, this gives a constant connection leaving the hands free to work and saves the occasional "bite" Cheers and thanks for sharing.
I swear Darren….you’re the best I ever saw….I can’t even imagine what it’s like to be that good at anything….you could jump start a potato. Well done dude. I’ll keep watching.
Lol! Mustie gets a JLO-Rockwell 340 CC twin, and I was at a car show only 1000 feet down the road and a fellow offered me 2 real nice 340 cc Fichtel and Sachs SS model high performance singles to add to my vintage 2 stroke engine collection, both stored in a heated garage for the last 40 years! Lol 😆 so we both got some cool engines! I have no doubt these Sachs singles are runners! YEE! 👍🏻😋👌 so we both got cool 2 strokes! These 2 were free as well! 🤘! That JLO Rockwell twin is a sweet runner, Mustie! Great catch! Smooth as glass too! I need to put a little pre mix into one of these Sachs singles and see if it will fire up! Also, when ya did the fire up dripping petrol into the intake, the first slow motion clip sounded like my 1940 2-71 Detroit diesel! It is a 2 stroke twin as well.! SWEET!! 👌😋👍🏻
I am always amazed when you have a problem , the way you will switch things around even if it makes no sense until you are sure there is definitely something wrong with the component, there may be a reason why the wires need to be hooked to the correct components and that was probably why it was put away to begin with, they lost spark , messed with it , switched the wires and never ran again. Maybe not, but it sure seems like it all went back to good pretty quick. Until the piece was missing from the carb , which who knows what happened there. Glad you found the rebuild kit, the motor sounded ok to me other than that ting sound that was suspiciously like the belt assembly hitting the table lol. Great vid , thatnks for bringing us along on your adventure.
Mustie1 to PT tech: "All this stretching is making me sore." PT tech: "Just keep doing your exercises and it'll loosen you up." Mustie1: (carries two cyl. engine to bench) 😅 Great video as always!!!
So It's basically a win on the engine. BUT when you were showing the snowmobile at the end of the video I could just make out the Toyota Cressida in the back ground!
In trying to keep the spring on the end of the starter . 2 half pieces of wire would work like modern keepers for valve springs and the part you made on the lathe would keep them in place !
Good morning Darren. I bought a similar engine at an auction. Looked almost new and if I remember correctly it is labeled Chrysler Aero-Marine. Auction tag said it was a diesel engine. It has 2 spark plugs, no carb or exhaust. Been maybe 20 yrs and I haven't gotten to it yet. But one day ...
When we were boys we used to light a match over the spark plug hole when the old Briggs flooded out. Worked fine but not sure how it would work on this engine. Probably engine on fire, a bad idea. Great video of this vintage rare engine.
Hey Mustie lad,, you are incurable, and I thank God for that. Always additive viewing, often surprising, never boring. Thanks for sharing and best regards from Ireland.
Great little engine, I have the exact same in my '70s Scorpion Whip snowmobile. The only problem I've found with them is the crankshaft seals dry out and leak air.
1981 into 1982, around Manchester, New Hampshire... was a REALLY mild winter. With some exceptions, I rode my motorcycle throughout the winter. I think the worst storm was in April. Explains why they didn't bother with doing anything with that engine in a sled. No snow!
Looks like a great project, coming together well, can't wait to see it scooting through the snow, thanks for sharing, all the best to you and your loved ones
👍👌👏 Very well done again and as always (video and work). After all those years I'm still waiting and hoping for the famous Mustie1 laugh as soon as an engine starts/runs for the first time! 😁 ;-) The engine sounds and runs good, no knocks, nothing. I was happy to see that there was a carb kit available. Additionally even including the missing part. Of course I'm now eagerly looking forward to watch the second part. Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards luck and health in particular. By the way: Get well soon, Sir.
I have 2 massey Ferguson ski whiz snowmobiles with these JLO Rockwell engines in them. They are a very temperamental engines. Like to blow pistons on the clutch side. Don't overlook the crank seals. Very peppy engines when properly sealed. I like them
That carburetor is a Tillotson HD which was one of the most common carburetors of the time along with the HR. Another common carburetor for that engine was a Keihin which had a square diaphragm.
That's a Tillotson model HD carb and it was extremely common on larger displacement snowmobiles until the mid 70s when Mikuni carbs took over. The part you're missing is the inlet control lever. Great carbs and easy to tune. Also, they're typically mounted with the fuel inlet on the bottom. Not sure how much of a difference it would make, just thought it was worth noting.
If you don’t install the carb upside down it will help too. I’d look for a 45° intake. That small fitting on the engine side of the carb is a primer sprue. Newer engines use a similar fitting for oil injection. The best thing would be to replace that carb with a mikuni in similar size, there are charts for conversion.
My eldest son was born in 81, labor day of 81, and then my second son was born in 82, damn hard to believe their that old now and I'm an old man myself.
For the life of me, I don't know why you don't build yourself an engine stand set up with a battery pack and switches with a proper electrical cut-off, maybe fuels either gravity fed or fuel pumped, with shut off's and some way to hold the engine in place. Don't get me wrong, I love watching you and your setup that you have, but I'm patiently waiting for that engine to jump right off of ol Doc Mustie's table or that jumper box to arch a spark and light up raw exhaust. I'll bet you've had your eyebrows singed a time or two. You are definitely entertaining. I was betting that you had one of those clips off of the starter
it's better being a part hoarder if you are a mechanic because in case of an emergency you can always grab it unlike when you had to search it online or travel long distance to get one
