The generator started and ran all last summer if I used starter fluid to get it going. But it would not carry a load more than about 1500watts. I have since installed a new carburetor and electric fuel pump. It's not in the water since so have not tested this improvement. I'm expecting it will now start but worried about it not carrying a full load. If so, could it still be fuel starvation? Hours about 2400. Suggestions?
