I wrecked my M7 and endend up finding a deal a buying another one the only problem is after the sled has been ran sometimes it wont start on the first or second pull. it takes like 5-10 pulls and a little throttle to get it going but sometimes it will start the first pull. It always starts 2-3 pulls when its cold but once its been running is when i have a problem. Did a little research and um kinda leaning towards the reeds being messed up. It has V force3 in it the air box has some fuel and oil in it and when i first got it i checked the spark plugs and ive never seen plugs that cardoned up ever. does it sound like im on the right track or should i start looking at something else being the problem
