Does anyone recognize this engine? I originally thought it was a Toro 25 from the look of the flywheel. However, the Toro magneto attaches to the cylinder whereas this one has a separate casting. Is it possibly an Echo 25?

it looks like a stihl 25.4 or 27 maby not sure

Thank you Ken. As I disassemble it, I will measure the bore and stroke.

I see a McCulloch logo on it… Which is also on the Echo engines. So it a Koritz (Zenoah) engine. I would say it’s in the 23cc range.

Can't tell for sure but I vote for Echo/ Kioritz.

Thank you for the reply. I am starting to think it is just a different or older model of an Echo 23.6.

The older 23.6cc Echo engines are better. Bigger transfer ports.....

What was this engine in you think? Blower...hedge trimmer...cement saw or weed whip? Could be a clue. Capt,n

I obtainsed both string trimmers and hedge trimmers. It could have been the hedge trimmer as several of the string trimmers had the 21.4 engines.

I couldn't see that good without my magnifier glasses sorry
