first time snowmobiling

Hey guys,
My nephew wanted to start his 1885 ski doo that his dad gave him last fall. I don't know much about snowmobiles. Is that the kill switch ( square button) on the handle bar. Should that be up to start, and pressed down shut off the engine? It started for about 20 seconds and stalled, I think now that the kill switch was pressed in. There's also a strap that he can wear on his wrist to kill the engine, if he falls off. Where and how does it connect to on the sled.
Thanks for any info.
Mike

not too fammiliar with the 85's, but yes, the kill switch should be up, there should be a "****" that the kill tether attaches to i think.

IIRC, the **** should be pulled out. It's alot easier to hit it in a panic situation than to pull it out.

If the kill switch was down it shouldnt have started at all! Could have been that it hasnt ran for awhile or whatever, some need time to warm up before the idle good.

it probably needs a good carb clean. we have an 86 suzuki 250 that had been sitting for about 15 years and it would start run for bout 10 secs and die, and over and over. finally i got the gunk brand crab cleaner that you dip the stuff in, dipped the stuff, let it sit and fired it up and it runs just fine. then i changed the plug on it and that really woke it up. before it was ok, but now i can open it wide open, let off and open it up and the front wheel comes up with out any pullin back. also is it 4 stroke or 2 stroke?

You know whats funny. I have several small and big motors laying around. Even with the kill switch on...aslong as the motor is warmed up...i can get it to putter for about 10 seconds..

But in your case. Pick up some carbcleaner...and clean it up...

The engine should not run if the kill switch is down, although some of the older sleds have a click type switch where there is no up or down - it's just on or off. The tether should just plug in somewhere on the dashboard or on the side of the cowl where your knees would point.

The kill switch shuts off the spark to the engine.

All sleds are 2 stroke except for around 03' they started with 4 strokes. There are only a couple of 4 strokes on the market so far.

Kill switch is on the right, light dimmer on the left. Kill Switch is Up to go, down to stop.

First thing to do is to make certain you have fresh gas, good compression, and strong spark. Also make certain the exhaust isn't plugged.
When I had an '85 Skidoo Safari 447, the muffler packing fell out and partially plugged the exhaust outlet. It made it hard to start, slow , and finally ended up blowing a crank seal.

By chance did your sled have a white hood? I ran the vin number through Ski Doo and they couldn't find the model. All the labels on the hood are completly worn off.

when you clean the carb, make sure to pull the bowl off and make sure the float is free too move, also eather clean or replace the needle & seat.the bowl will hold alot of contaminants,also put on a new fuel filter in line.

Thats not exactly true. The first snowmobiles were mostly 4-strokes. It wasnt untill the late 50s to early 60s that manufacturers started use 2-strokes.
The early Polaris sleds all used Kohler 4-strokes.
The manufacturers started to see the advantage in both power and light weight in 2-strokes, so they went to those.
Also, there are several 4-stroke sleds on the market right now. Yamaha has the Apex and Attak, which use a 1000cc 4-banger. Yamaha also has the RS Vector, RS Venture, Nytro, Rage and they also have a utility sled (I think its called the "VK") that use a 975cc triple-cylinder 4-stroke.
Polaris has 2 4-stroke sleds, the FS and FST. They use a 750cc twin-cylinder engine thats made by the German company, Weber. The FST is turbocharged, the FS is not.
Arctic Cat has a sled that uses a turbocharged 660cc triple thats made by Suzuki.
Ski-Doo has a 4-stroke sled that uses the V-1000 engine (Im guesing its a 1000cc v-twin, but Im not a Doo guy, so dont quote me on that).
Yamaha has by far the best 4-stroke sleds, but they also have a lot more experience with all of the crotchrocket technology they can draw from.

Also, don't forget the handful of sleds that had the Sachs Rotary engine in it, just like the Mazda RX-7
