Thanks for the input. I am going to start looking at the ignition system because I have already replaced the fuel accumulator and the check valve by the fuel pump. There is only one check valve, right???
When it does fire, it usually is rough and there is a vast amount of fuel in the exhaust. You can smell it as it rumbles until it clears the excess fuel and then it is just fine, runs like a champ. Although, it does seem like I am getting horrible gas mileage, but I can be certain because the odometer is stuck.
