After 25 years of being away from the sport/hobby I just bought another snowmobile, I recently purchased a 1980 Trailfire 340. It is not in the best of shape, but I like it and believe it is a good starter sled. The fella that I bought it from told me that it would run for about an hour and then die. The first day I rode it for a couple of hours, died once but I was able to get it restarted with no problem. The second day rode for about 10 minutes stopped to get my wife. When I tried to restart, it would not. I checked for spark and got spark from one of the plug wires but not the other. I purchased a parts sled at the same time and changed out the coil and the coil pack, the problem remained the same and still would not start. I have good compression, believe I am getting fuel. Any tips, suggestions would be greatly appreciated.
Also looking for good places to buy parts. large selection a must.
Thank you in advance

I cant help you get yours going, but the best parts place is right here. I know several guys on here with large stashes of stuff. Post to the classifieds. Otherwise there's evilbay, central snowmobile, etc.

Hi you didnt state wether you got the spark back in that cylinder or not. If it were mine i would start with grounds then i would unplug the kill switch had one go bad and it toyed with me for two days never acting the same way twice . Then theres the possibility you got 2 bad coils . If you are getting spark on both cylinders rule out gas put a shot in the carb if thats it start at the carb and work your way back with it being a new sled to you thats probably not a bad idea anyway. The one thing you never mentioned thats commonly over looked is plugs . Did you change them ? If not do so first! Though rare sometimes when they foul they will quit giving spark when hot then get worse til it quits all together. Good luck !
