Put it this way, I picked one up free in late 2017, seemed good, then severely sliced open my finger when it kicked back, then I left it for a while. Cleaned the carby and set points and ran ok, but clearly a slightly blown head gasket.
The engine is a suffock punch with updraft Zenith carby - and a sardine can shaped muffler. I looked, and the gasket needs to come from UK costs about $45 incl shipping
They are really well built though
