Okay so here is the deal... I bought a 1979 Arctic Cat Jag 340 Twin yesterday for $300. Thing looks great for the year, but it needs some work. No problem, but it was sunny and warm and lots of snow on the ground, and I have never really been snowmobiling (long time dirt biker) so I bought the damn thing and went into the woods for about 4 hrs, and even got to do some lake running.
Problem is to get the damn sled running I have to take off the spark plugs and pour some mix down in the there. It'll fire up on the first pull everytime after that - stop for a couple of hours and have to do it again. Also it idles REAL high, like 'I'm going to blow up' high. Smoke everytwhere. I tried to turn down the idle but no luck. I drove it anyway :thumbsup: because it was so nice out.
Now the guy I bought it from said the crank seals need to be done - is that the cause of my high idle? If so what is involved and what parts do I need? I have a service manual off ebay on the way and am not afraid of wrenching. I've also been over the parts microfishe this morning.
Any thoughts?
