Engine help
Ive recently bought a Tamiya fs-12 engine and I'm struggling to start it. Fuel is getting through the system, the glow plug works and I've tried tuning the air fuel mixture and it still won't work. When I try the engine gets hotter so I think the fuel is igniting but not keeping going.

You can start leaning it out to see if it pops. If all else fails time to pull the sleeve out and check the pinch.

Less technical
Open the engine up, pull the piston out, pull the hollow cylinder (sleeve) out and then by hand if you can push the piston to the top of the cylinder (sleeve) with little to no force you have no (pinch) or compression and the engine will be hard to start. It "should" start to get tight about 1/2 way up.
A sleeve looks like this / \ but not that drastic. It gets tighter as the piston moves to the top.
Leaning it out means closing (clockwise) the fuel screw. Do this = to 1 hour on a clock at a time.

It gets tight about 3/4 of the way up
