Hi All,

I think this comment is a bit too late since the issue has already been resolved. When I first read this thread, I knew the mower is already in good running condition. Mowerfreak has already pointed out the issue in the right direction. For everyone to know, when this PT runs fine on iddle and suddenly revs high then stops at high throttle, the problem is there's no enough fuel in the reservoir for higher throttle demand and no matter what, only focus on the fuel supply. You can reproduce this phenomenon by switching off the fuel tap and runs the engine at high throttle until it runs out of fuel. At the end of the fuel supply, the engine will revs high then stops.

Cheers,
