Anyone know what engine this is? It has a 20x10 prop and the markings you see in the pics. It dates to the mid to late eighties and has CHIgnition.I don't know the displacement eiither. Thanks in advance...Charles

Hi Charles,

It appears to be a conversion of a Sachs Dolmar chain saw, maybe a3.2 cior a 3.7. Looks like it might have a C&H or a RC ignition system.

I agree with Carlos.Ive had a few sachs and i believe its the 52cc[3.2].
Because of the shape of the transfer port i believe it came from a Sachs Dolmar model 115 chain saw.The model 111 has a straight up and down port.The model 115,has like a nuckle,like yours.
Is there a number 44 in front of any letters anywhere on the cylinder?
If there is, its a 52cc for sure.That number is the size of the cylinder in MMs.
This how to tell what CCs it is.

Looks like a T&G conversion. If it is the 6 bolt pattern on the prop hub will have a 1" diameter, everybody else used a 1.125 " diameter

Thanks for all your help.There is no '44', only the markings you see in the pictures. I don't know what a 'T&G' is but the prop hub diameter is 1-9/16" with a six hole pattern. I'm guessing the displacement is in the 50-60cc range. At any rate, I'll fire it up this week to see if it runs.

Pretty sure it's not a a Sachs, unless its one of the smaller ones. The smaller Sachs, 2.2, 2.4, & some 2.6 ci used KS cylinders. The 3.2, 3.7, 4.2 used Mahle cylinders until most recently. All of the 3.2 and 4.2 Sachs engines I own, have Male cylinders. The 3.2ci, is marked "44", the 3.7ci, is "47", & the 4.2ci,is "49".This is a Mahle 3.2 ci cylinder from an A&MSachs conversion.

It says T&G on the muffler

Not the diameter of the hub, but the diameter of the bolt pattern

Since most engines will accept a variety of mufflers, the 'TG' on the muffler probably doesn't mean anything relavent.That and thefact that I can't find a TGengine searching the web. There are no other markings other than the ones seen here in the pictures so the '44,47' etc doesn't do much either. On that thought, If I squint my eyes the figures in the casting appear to be SK or KS but I can't find anyting on either that would aid in identifying the engine.
It's a mystery to me. I thank you for the efforts though.
