I live just outside Rochester NY, got hit by the big wind storm, no power. First time I've been without power more than 8 hours in the 11 years I've lived here, and first time I've been without power for more than 4 hours in the winter time.
I have this CaseIH 3500W inverter generator that I use for camping, plenty to run the basics. Always been hard to start, and last summer it developed this habit of running for about 30 minutes, then acting like it's out of fuel and quitting.
When I gravity feed it from my test tank it runs like a Swiss watch under full load for hours and hours.
So, it is a fuel feed problem. I have replaced the fuel pump, the fuel filter, and the lines from the tank to the carburetor. It still won't run off the internal tank for more than about 30 minutes.
The fuel pump is fine. I can suck/blow on the impulse line and it shoots fuel. However, when it is connected to the impulse port on the intake while the engine is running, it barely dribbles any fuel at all. The impulse port on the intake is CLEAR; I took the carb off and ran a wire through it.
Any ideas where on the engine I could get a better impulse for the pump?
