Trying to get the pump shot to come in hard and fast. It’s my understanding that #1 position gives a longer duration of shot while #2 position starts off already into the fat part of the shot.
My plan of attack is to pull carb back off and verify t-slots are still set. Then back out idle mixture screws 1/8-1/4 turn and test. If it’s still there I will try the 37 shooter. If it’s still there I’ll back the timing off a degree or two. If that doesn’t get it I’ll feed it a bullet.
