What do you mean it "wont turn over?" As in it wont start or the flywheel wont move. Wont start would be a number of things, bad fuel, not enough/ too much fuel, idle gap is closed stuff like that. Wont turn over could be really bad like a locked up motor or hydro locked. If its hydrolocked, like the above post said, remove the glow plug and crank it over to clear it out. Then reinstall and try again. Need a little more info from you so we can help out more, like type of engine, more details other than it wont start.

sorry i should have been more specific the flywheel does move. it just wont start. its a .15 hpi engine. ive opened and closed both screws and turned both slightly and kept trying. ive also primed. i also removed glow starter and pulled. i re primed multiple times and still no start idk if i have the screws set correctly or what. (when i say screws i mean the things on the carb theres a small one and then a bigger one)

Maybe the spur gear wasn't the only problem, go to hpi's website and look for the factory needle set points and go from there.

ive tried adjusting both. but im new to nitro and i bought this car used. oh and btw i dont have the spur gear yet im just trying to see if this motor will start up so it wont be able to go anywhere without the spur gear in. but i assumed i could still start it up. by the way which screw is which? theres a small one and then a bigger one? and as far as adjusting them?

sounded like the roto-start or pull start one way bearing could have been slipping. I remember on my old Muggy I had to blow on the fuel line to get some fuel in on the one way to make it grab.
