Hi again Bruce,

I'm not sure how I can get a photo to you but am wondering what the distinguishing characteristic of a powertorque engine would be as it's possible that this is a powertorque engine.

I have taken the carby apart and cleaned it, swapped the primer cap and main jet off a working mower but still the mower over revs and is hard to start. My instinct tells me that the carby is the problem, it is G4 plastic body and these carbys are simple in design. I'll take it apart again but what should I be looking for in order to fix the carby?

Regards,

Tiger
