1975 Ski-Doo Olympique 340 REVIVAL! 

Love the old Olympics my first ride as a kid was on a 75 300 twin

Thanks for this video! Our family's first sled was a 1977 Ski Doo Olympique 340. What a great sled.

That a hot engine. They ran then in a yellow ski Doo. ,50 to ,60 and up.i sold sleds but kept the 440 had it in many sleds loud as hell. Ski-Doo bombardier

Thanks for you videos. And your advice with finding the problem out. if it wasn't for you my old skidoo would be going for scrap I had no idea it was that easy to fix. Cheers to you man. 🍻

One of the biggest pos ever built. Had a 75 panther at the same time just hit the key and go. The ski doo made me walk home every time.

This is going to be priceless when I dig into the skidoo 340 I picked up today. Also have a 79 moto-ski 340, parts interchangeable. Thanks for doing this video!

I have a 1977 Olympique 340 that I use for ice fishing up here in Manitoba. It purrs like a 44 year old kitten! lol Paid $500 for it and have been riding for 12 seasons on it. I built a wooden "trappers box" between the seat and tunnel on mine and it raised the seat up about 6 inches. Easier on the old back and knees to ride on now.

Had exact same machine great fun!Greetings from St Antoine Abbe Quebec Canada!

I was given the same sled as yours and I am going through everything.There was 2, 5 gallon pails of pine needles removed just to get started.Ended up pulling the chain case because of broken bolts.It seems like everything is there.All the fuel lines were laying on the frame and disintigrated in the tank. The guy that gave it to me said he bought it new in 1975 so I will have to replace the battery.Good score.

Hey just found your channel will definitely give ya a shout out super cool sled man

I did a double take when you shut the thing off with a light switch! Cool video

it must have been absolute murder editing this much footage. great stuff! It almost felt like I was right there getting my hands oily just watching it.

Nice one! Where you at Matt? That ride along the river through the woods was sweet!

That's awesome you put a light switch on it for a kill switch 🤣

I have one of these that I swapped a 377 into from an '85 Safari.

Great old sled.

Matt, nice work, another great video. You have inspired me to go work on my 77 Olympique 440. Or should I go work on my white hooded 75 Oly 300??? Neither are ready yet for snow yet and I've never ridden them. Decisions, decisions......We gotta preserve these old gems.

It would be less cumbersome to use the Tillottson integral fuel pump instead of a separate Mikuni fuel pump. It would provide more space to work around the engine and it would look cleaner too.

We used to have the exact same snowmobile when i was a kid but ours was widened in the front and had wide plastic skis. it helped a lot for the stability ours was a 1975 as well but there was a big issue with the carburetor when the engine was hot there was a steam lock in he fuel line so we ended up replacing it with a Mikuni carb instead it ran nice with that until there was an leak in the seal behind the variator and we took it to a repair shop to get it fixed but unfortunately the whole crankshaft came apart when they was taking the variator off so the whole engine was replaced by one that was newly renovated and we also got a new seat and a new track the snowmobile that all of these items came from was damaged in a crash

Uuh...you forgot to attach the pump vacumn line!

I had one of those back in 1989 and it was 340 fan and it ran perfect until the kid I sold it to ran his Lawnboy summer premix in it and burned the pistons and blamed it on me saying I sold him a Lemon of a Snowmobile

Looks like it's going pretty good. Does the guage work?

Hey Matt, love the videos, almost makes me want to trade in my 22 Kaos. For a Oly…. But curious as to wether or not the 110 single pole switch was stock.

Looks like the fuel lines got put on in reverse from when you started the video. Which way should they be on this carb? I'm trying to figure this out on a sled I'm trying to resurrect that didn't have fuel lines in the first place.

How do I fix a spark on one cylinder got two new coils have the same machine 79 340 is what I got spark on left right side no spark new coil and plugs still no spark on right any ideas check the points and if so I gotta take the flywheel off right ?

'?Theres another guy I watch hunter gatherer he fixes eerything has a sonic type cleaner n just throws all his carb fuel things in it he gets carb cleaner about 20 bucks a gallon. just turn it on for bout an half hour to an hour it might be a harbor freight unit but does a really good job cleaning all carborator parts. And has a small like scissor lift pretty cool main ly for motorcycles but hes had cars n vans on it to. I think its very slick for mowers atv's garden tractors etc just a small like garage type shop

Can u run a 340 air cooled engine on a 40 to 1 mix?

I just sold ski Doo 377 and a rare ,trx 340

N G K plugs only bloody two strokes!

Talks about using to much powing screwing the carbs together, as i watch him crank on them

Why would you run ethanol gas in it ?Never do that with any small engine.

Low soeed jet 3/4 turn out...high 1 1/4... Adj accordingly thats a baseline

Uh primer line

1 cyl. 😕
