[QUOTE="a454elk, post: 720628, member: 23609"] Took my carb apart again and this time I fully disassembled the accelerator pump and found dirt on the under side and the diaphram was worn through, a hole was on the rubber side. I guess that'll explain the problems, the jets are completely clear but I think that the jets are getting clogged due to the dirt getting past the diaphram and into the circuits. It also backfires because it sucks air into the pump on deceleration. That should explain the backfire on yours but I think your jets may be screwed up or the air fuel mixture is set too rich. Maybe your pilot jet was changed to a real rich one. My local dealer ordered the diaphram for me at 18 bucks.:scream:! Oh well, we'll have it by the end of the week, I hope. Update to follow....
