I have a new .18 tm and last fall I put a tank and a half through it then my car broke and I away I got it out last week to finish the break in and after the third pulll it started but the throttle was stuck at a quarter throttle so I shut it down and fixed the problem then tried to start it again and the glow plug went bad so a week later I tried to start it again and I cant pull it over so I pulled it apart and the piston was stuck about 3/4 of the way up. I freed it up but it wont turn over all the way it stops at the 3/4 mark very tight on the pinch. So how do I get it to turn over? I never had this problem till now. It always pulled over no problem till now any thoughts or sugesstions will be greatly appreciated! Thanks Dean
