ORIGINAL: BOHICA29

the plane has been check by an experience flier it is ok. i think i have a defective starter torqmaster 90 will not spin the propeller
This is unlikely.

It is more likely that either your battery is not supplying enough voltage to the Torqmaster, or your engine has so much compression ( e.g. it's new ) that the starter cannot get it over the TDC position as you are doing things now.

You should turn the engine counter the revolution direction of the prop until it stops, put on the glow plug ignitor and then put the starter up to the engine spinner, and finally hit the starter's switch.

This will give the engine a "running start" so to speak where during the first part of the revolution it has no compression resistance.

Also note that if this is a brand new ABC engine, you may still need to help it a bit.

On their very first runs, crank the engine over by hand to draw fuel into the crankcase, and then I often need to warm up the cylinder head ( particularly on SuperTigre's, GMS and Tower Hobbies engines ) with a hair dryer.

This expands the head enough to make the initial starting a bit easier, though usually after that very first 4-5 minute run, this is no longer needed ever again.
