I was starting to notice a little bit of uneven acceleration when wide open. I checked and the intake rubber elbow hose clamp on the intake throat to hose joint was not tight. In fact, when I tried to tighten it, it seemed stripped. I removed the hose, cut the little rubber 'keeper' tab that attached the original clamp on off. Then put the hose back on and used a much heavier duty clamp to tighten it back up. One test run proved that the fix worked. It must have been leaking. Tnx for the 'heads-up' lil' goat.
