Can anyone help identify this engine?
I have reciently aquired 3 x 31cc motors i want to convert to join my Ryobi aircraft hanger.
The question is i cant identify them for parts. One came from an older Ryobi weed wacker, the other two came from Mc Cullough blower vacs. They share a very similar crank case to a ryobi with the 2 bearing half crank etc, a better con rod but cross flow barrel eg Zanoa. The fly wheel has fins either side for cooling. All are long shaft with a 7/16th unf thread.

Any help.

A picture is worth a thousand words is the back plate (carb mount) white?

the fins on both sides sounds like a mac engine instead of a ryobi

Hellow converts: I want to convert a Toro 25cc myself. This is something I enjoy doing. Where can I find the Toro 25cc at the most resonable price. Thanks Capt,n

negitive on that all plastic parts are black as in a Ryobi. 4 screws hold the barrel down.

It sounds like a Mac 28 or 32 to me.
How about that picture?
