Hi wce
Yeah I tried that the idle screw doesn't seem to make any difference no mater what position you move it to the only thing I can adjust is the fuel mixture now here's the silly thing if I pull back the linkages from the governor by hand it doesn't seem to stall but if I move the control leaver to slow on the handle bar it goes to a slow putt till it dies as though it's starving. I thought maybe it's shorting the kill switch early but it doesn't look or sound like a kill stop it seems like it's running out of puff and trying to hang on but cant. It sounds nice on high revs but not over reved or screaming, I also noticed you can drop the speed very quickly with minimal movement of the control but still maintain a good inbetween speeds unlike some engines that just drop from high to low revs with out much inbetweens.
