Hey Steve, where are you located? Do you live in California? Our crappy gas has so much alcohol and other corrosive agents in it that it will dissolve the accelerator pump's rubber diaphragm in short order. I've had to replace mine twice within about 6-7 years. If you replace your accelerator pump, don't buy the standard black rubber pump that all the auto parts stores stock. Get one that's suitable for the gas - I think the green or blue versions are more resistant to our crappy gasohol.
