I have been trying to dial in my carbs (dual weber 44 idf's). I recently made a jet change (and no other changes). Now I am going lean and popping on decel. I did not have this issue before the jet change which makes my doubt an exhaust leak. My air fuel gauge reads 14.5 at idle, 11 on accel and 17 on decel. The changes that I made were decreased the air corrector jet to 200 (from 210) and increased the main jet from 145 to 150.
Since it is so freaking hot out I want to be prepared before going outside. The engine is running fine. Head temps were around 290-300 after hard acceleration. Ideas?
