Ok got a brand new trainer with a megatech m46 engine. Filled it up and started the bad boy. Ran for about 15 seconds and when I removed the glow igniter the engine quit. AFter a few more unsuccessful tries to start up the engine the next thing i know is the piston has jammed up and when the piston is all the way on the top (compression stage) it becomes almost impossible to continue the cycle.

So i removed the glow plug and put in two or three drops of fuel to lubricate it. And it became a bit smoother. Then I hook up my electric starter and after three or four spins the the piston jams up again. But this time it's not that badly jammed up like the first time but it dosen't allow the electric started to move it. So before trying anything else I thought I would post here for help.

Thanx.


(*Forgot to add this earlier*)

-During the first time when it ran for 15 seconds there was no smoke whatsoever (muffler blocked ??)

-When I turn the turn the prop in the opposite direction the carb spits fuel out (normal ?)

-Some bubbles in the fuel line (I heard that's bad : so how do i get rid of it ?)
