Think I can get a new piston and rings on ebay and victa spares has the powertorque head gasket.

Trying to keep cost low so any advice around honing at home welcome. Don't really want to pay labour charge for someone else to do it.

I guessed they were imperial but only have limited imperial sockets. Guessing its 5/8in as 15mm too small and 17mm too big.

Lots of questions I know..
