Hi All, I notice with most 'power-torque' engines the 'O' rings also fail, particularly the one under the starter, and of course the carby 'O' rings. Another good tip is to remove the muffler and have a good eyeball through the exhaust port at the condition of the piston and rings.
Good tips DJ, when I posted this initially I was directing it toward all mowers/small engine stuff not just Victa but wasn't sure where to put it so I put it here. You're right about the o-rings with the powertorque, that engine works on vacuum so the slightest air leak causes problems on those.
