Just pulled this sled out of the garage in December and had it running great until it broke off reeds and ever since then the sled hasn't run right since. I had installed new reeds and put new main and pilot jets in and adjusted the mixture screws since the sled had last run in the mountains. The sled with the new reeds and jets is spraying fuel out of the back of the carbs and is also backfiring at low rpms. The sled now will only rev to 3500 or 4000. I had sled fixed until the fuel line came off and the problems reoccurred.
