Well I checked the accelerator pump and it works fine. I was actually trying to prime the engine before with 3 pumps of the pedal. I thought that was enough but when i went to check the acc. pump today i ended up squirting it 5 or 6 times and it started. How many times do you guys pump your pedals to start your engines after about a week of non use? I think i am still going to replace the pump.
