I had my injector pump rebuilt...previously posted a question about advancing and retarding by rotating the pump mount. Thanks Dieseltech for confirming that information.
My problem is now it really doesn't run well under load. When it starts it actually seems like it is putting out unburnt fuel- white exhaust, but not steam. Once it is up and running at 1500-1700 rpm it clears up and sounds pretty smooth.
I put the brush cutter on it and tried it out, bogged down and struggled even to get back to the shop, exhaust looked blacker...almost like the air intake was plugged, filters are ok.
Rotating the pump didn't seem to make much difference. Is it possible that the timing gear lifted out a notch while I was attaching the pump back to that gear?...it can only attach onto that gear in one position. Does that gear just float in there when the pump is not attached tight?
What else could I have done??
Any help would be appreciated. Thanks, Grant
