Hello,
I have a 2 stroke 61 engine very hard to turn due to the high compression, I have never had an engine like this before.
My starter won't turn it thru the compression, It does turn all my others including a 25 CC gas engine,

Any Ideas.
Also I don't know what brand it is, It has GF on the side.

Thanks for looking
George

It will not be too much compression but more the cylinder nip that occures on ABC/ABN engines. This means that the engine will be on the tight side untill run in and looked after will last a very long time. I had an OS 46FX the same and lasted 15 years before brain fade took over and put it in the dirt.

Cheers.

You can probably loosen the glow plug to start it the first few times, after that it may loosen up a bit.
