Been struggling with this and nothing. Charles has a good memory. It was, as I recall, just #4 that was fouling. Are they all fouling now after idling?

November 21, 20222 yr Author comment_647402 Let me explain this better: I adjusted the floats during the pandemic in 2020 when i had some spare time. I did this using a float sync device built and sold by one of the members here. If i close the fuel adjustment to 2.5 turns clockwise car has no power when accelerating. it even pops at the exhaust when releasing the gas pedal.

November 21, 20222 yr comment_647408 Is your clockwise adjustment your view from the top of the carb or is it looking at the adjustment screw from the bottom of the carb? This makes a huge difference. When we describe turning the mixture screw clockwise, we're imagining looking at it from the bottom of the carb and we're leaning the mixture out. If you're imagining looking at the screw from the top and turning it clockwise, you're richening it. You could pull a dome and watch the nozzle as you adjust the height and tell us if the nozzle rises or drops when you turn it clockwise.

November 21, 20222 yr Author comment_647410 you close the jet all the way up and then you turn 2.5 turns from the base line. Lean is when the jet is flush with the bridge of the carb. The nozzle drops when turning it.
