2 questions sledders. First, 1986 Arctic Cat Pantera 440. Main wiring plug is installed on only 2 of 4 prongs. Wired for electric start, ignition switch has been pulled out, runs 1/4 throttle and up AWESOME. Refuses to idle, and has no lights or kill. Must choke to shut down. How to fix? (Guessing clean carbs, but what about the wiring?) Second, 1996 Ski-Doo Touring, used to be one of my uncle's machines(owns a touring business in North Lake Tahoe). One big plug near the headlight is unplugged. Runs great, but no light, no flywheel, so no electric start. Is there any advantage to electric start? Besides being a lazy a*%?. Would like to get it all working as original though. Second problem. I got this machine for free. Looks like it lost a bearing on the driveshaft, and the shaft came loose. I have been told to pull the case cover and extract the shaft that way to replace the bearings. Sounds reasonable, but is there anything special I need to know? Also, how do you loosen the track. This thing has a 380. How fast will it go. I am fairly new to this, only 2-3 years experience and don't see any need to go 70+, but I would like to know if this machine is capable of 60. That is about my limit. Thanks.
