hey guys i have a super tiger 60 engine and a friend just gave me another one because he coudon't start it and told me to try. he bought it from a guy who said that it worked fine but i guess not. i tryed setting the needles from factory to every which way and still all it does is give a tiny little sputter and then quits. its not the fuel and not the carb because i took the carb of the other engine thats exactly the same and it does the very same thing. i've tryed new glow pugs and still nothing. i've tryed priming it from a little to lots only to hear the same little sputter. but when i heat up the engine a bit with a heat gun it doens't even sputter. it seems to have decent compression, but not quite as much as my other one that works. i'm just wondering if it could have something to do with the piston or head. i took it apart today and i don't exactly know lots about those engines but to me everything looks fine. i cna't see anything scored or pitted. so i someone has ideas to share i'd really appreciate it.
