Ok Norm,

I'm not sure which carby I have. Its a full crank with a plastic carburetor but it has the idle adjustment already there although it does not seem to make a lot of difference. Strangely this mower does not overrev like my Powertorque. It runs very nicely if I can get it to go.

The other mower I have is a Powertorque, carby looks much the same but no idle screw. The Mods are different aren't they? I'll swap over the carbs first, my Powertorque starts very easily so its carby must be OK although it runs too fast, can only use about half throttle.

Thanks again for all your help.
Jeff
