This is what i was thinking. The plugs looked brand new when i pulled them besides excessive fuel on a couple, but they act like they are fouled. Thanks for the help. We just got a damn blizzard here in MO, so I should have some time to work on it these next couple days.

 

Do you have any update? I seem to be in the same boat. Excessive backfiring when trying to start. I can only get it to idle after 1,000 or so attempt's..
