Re: fuel starve

Bet you primer bulb is between the filter & motor. Sounds like the fuel in the filter is draining back into the tank at the end of the day. If so put the filter between the bulb and tank. The bulb has a valve that should not allow the fuel to return to the tank.

Re: fuel starve

Pump is OK. Otherwise it would not draw the bulb into a vacuum. Once again, I'm with SoLittle on the bulb theory. A soft bulb can only happen between the tank and the engine. Remove the water/Seporator and see what happens. Could be a bad water seporator!...<br /><br />EDIT: put new bulb on. They have been known to be bad right out of the factory...Try a 6 gallon portable tank with a new line and bulb and see what happens...
