I can answer most questions concerning snowmobile repair, including vintage and newer carbureted sleds.
I recently owned a 1978 Arctic Cat Lynx that I repainted and restored, a 1973 Ski Doo Olympique 440, a 1986 Arctic Cat El Tigre 6000, a 1990 Ski-Doo Formula Mach 1 and a 1973 Yamaha SL338C. I currently own a 1990 Arctic Cat Jag AFS Deluxe 440. I have rebuilt the carbs and fuel pumps, replaced tracks, slides, suspension,repaired chain cases,general body work, fixed the electrical on the sleds, and do just about anything possible with a sled. I used to work at a professional auto shop. I have accses to manuals and other helpful information, including good places for cheap parts. I am also a state park certified snowmobile operator
