Ran the sled last season, was running fine when I parked it, started twice during the summer started it for a few minutes, last week I stated it and ran like crap, I cleaned the carbs it was missing at low end, found some dirt in them, reinstall the carbs and ran for a few minutes at slow speeds, 20-30 km/hr , then felt like it ran on 2 cyl, some backfire in the exhaust, shut it off right away , thought maybe that there was a mice nest in the exhaust, so I removed the exhaust to find that #1 wasn't firing, exhaust on that cyl had unburnt gas and oil in that port, very dark and wet compared to the other 2, no mice nest in the exhaust, I was thinking coil , pickup, stator? anyone had a familiar problem? Tx all!
