This is puzzling me. I have an old Simplicity 7hp walk behind two stage at my fiance's house. It's always been a good unit.
This year it runs fine on level ground or going uphill, but fuel leaks out going down hill and the engine sounds like it's dying.
I took the bowl off and cleaned it. I adjusted the needle screw and it was purring nicely.
It ran fine on level and uphill, but downhill I could see the gas dripping off the bottom of the bowl. Next time I get a chance to work on it, I'll leave the shroud off it and see if I can locate a source.
But before I do that,
Anyone have any ideas?
