RE: rare 50 cc engine
Sachs Dolmar,3.2,orange case,if it is one ring it is a model 115,chain saw.I have one.What was the name of the engine company that used sachs engines.They went out of buisness years ago.
The engine size was a 52cc.I have 2 of them i can not remember the name.They where kinda known for there crankshaft problems.
That is why we put different cranks in them.they where silver machined case.But looks like a Ralph conversion for sure.
