sled has new motor, 1200km on it, 5300 km on entire sled. Its a 2002 summit 700. went out ripping yesterday and today. temperature is -25. was taking it easy because its cold out. sled sputtered then stalled from about half throttle. i took out the plugs, they were a quite light colour. turned the motor over by hand, everything seemed smooth. let it sit and slowy pulled it over and it seemed fine so i fired it back up. let it idle for 10 minutes, seemed fine so i gently started driving back home. Throttle got stuck open and i had to kill it and then pump the lever and it went back to normal. kept driving. about 1 mile later engine quit again. i instantly tried to pull the motor over to see if it was seized, it was not. pulled the plugs and they have a grey tinge to them and are not oily at all. let the motor cool off and she is seized, not solid but damn fricken tight. and it smelled like burning terribly.
my first question is how much oil should there be in the oil tank. i mean it was fairly low, about an inch and a half in the bottom but the oil light was not on, and the oil level was still barely above the minimum mark. (that was my fault should have filled it up)
second, is it possible a peice of ice got in the carb and screwed it up? the foamy thing was off the top of the air box. cuz i have NEVER had a problem with the throttle getting stuck open, and it just so happens it did right after it quit the first time.
any suggestions would be great.
