I changed fuel pumps because the other one that was on it was the wrong one and would only run good when I would squeeze the bulb. I put on the correct fuel pump that I ordered from Sierra, but now gas is coming out of the exhaust and will not run at all. The first time I tried to start it and was squeezing the bulb, gas came out of the front of the carb. What I am wondering is this correct, did I just flood it badly or is something else wrong. The carb. was rebuilt just a couple months ago.
