Stihl pole saw or possibly a poulan , would know more if you showed the symble on cylinder

Its the 25cc Toro or Troy built engine.There was a guy selling 4 of them to a box on ebay a while back.I bought 2 boxes and sold all the engines after converting them.
Best prop is a 16x8.
7000-7400
Attached is a couple pics of mine.

Thank you guys for helping identify the engine. I ran it yesterday with a 16x8 prop and got 8200 rpm. This is my first converted engine and I was wondering what oil to use and what is the best mix ratio? Also is there a place I can buy a muffler that will fit it?

Thank
Kevin

Good numbers.Maybe its been run in or has a different carb.My numbers where stock carb and just the gutted muffler.
Any muffler that fits the G23 or G26 will fit.Already tried them,there the same pattern.
Actually this motor is a clone of the Echo i believe.

Maybe lower elevation helps also.Im at 3000-msl.

Thats the Mac MB 290,it will spin higher w/apc prop and a velocity stack on carb,probably just fine as is though,good luck
