I just bought a used CEN mt2, and it has started and run for about a minute... only once. Usually when I try to start the car, nothing happens (Which I assume to be a tuning issue) but whenever I do get it started, it only runs as long as the starter is on the glow plug, which if i remember correctly, is something that I shouldn't leave on. I had a no-name truck a year ago, and I never had this problem. Also, I'm assume this to be another settings issue, but with the gas there are drops of fuel leaving the muffler as well. Any help?
Thanks,
Jack

Fuel will drip from the pipe, that's normal. The leaner you make it the less there will be left over, but more chance of killing your engine. After break in you have to change plugs. If my truck wont stay running after I remove the glow starter, I'll change plugs and it stays running after the glow starters off. CEN's site should have the stock settings for your needles, if not someone might put it here. If not, wait some time and start a new thread here or on cen's forum site on cenracing.com
