i have a 2002 honda recon 250tm and i need to know how to set the timing as it has three marks on the cam sprocket. the marks are 250, 350, and -. i tried to line it up on the 250 mark and i got it runnig but it is missing/backfireing out of the exaust when you give it gas, and it wont idle, so i figured that i have it a few teeth out. CAN ANYONE HELP???


Thanks!
