Las week I bought an estate. The friend of the estate told me this engine was a Ryobi 31 cc conversion. the owner changed original carb ( with primer bubble ) for a walbro. I have it listed here in RCU for sale and was told by a member it is not a Ryobi, they did not say what it is.

Any help out there?

Maybe Homelite 25cc

Hi,
It is a Homelite trimmer conversion. Either a 25 or 30cc. Take the muffler off and look in the exhust port. If it has a bridge, it is a 25cc, if not, it is 30cc. They run good. It is better then a Ryobi.

thanks dave,

this one does have the bridge/web in the exaust port, just a 25cc.

They start easy, run great and last a long, long time. Great for a biplane or a Cub that needs nose weight.

It's a Homelite. BTW they general cast the displacement on the bottom of the cylinder.
