Well in trying to cure my decel backfiring issue I bought a 48 pilot thinking I would go up one from the stock 45. Man what a pain in the butt to change the jet? Do they make a special small screwdriver or something? I loosened the carb boot but the carb will barely turn to access the bottom of the bowl because it looks like the top of the carb is hitting the motor mount above it? Is there a trick to twisting the carb? I basically had to do it by feel because the carb doesn't turn enough to look up it and I had to use a screwdriver bit from a cordless drill to fit up there and then turn it with a wrench. Oh Grayracer you were right about the 45 pilot. After getting the pilot jet out I found out it has a 42 PJ in it instead of the stock 45 so this is more likely my problem. But since I bought a 48 I didn't get to put it in to see if that will fix it since I need to run by the shop tonight and see if they will trade the 48 for a 45.
