Hello all,

I have been mucking around with the poppet valve settings on a Power Torque, and then taking it for a mow.

I know the catcher/mulcher supposed to be set on C, but having tried A I don't really notice a difference apart from a lower revving speed. It still seems to cut well and throw the grass into the catcher.

Have any of you tried this yourselves? What did you find?

And I haven't bothered trying the "3" setting, and have no idea what that would cause.

Edit: for reference, this is a steel based Commando I picked up and got running again. Dates from early 90's from the engine. I know some late model PT's have a lower rev range, so this is something else to think about I guess.
