The "825" Claw (1.42" venturii & 1.75" throttles) on my car is currently set up w/ .035" primary & secondary accel. pump nozzles. I haven't bothered testing different sizes, since the car does seem to respond OK this way. However, I'm curious if other street/strip (or heavy strip only?) cars running 4150-type carbs have responded to bigger squirters than this. What really got me thinking about this is seeing the spec sheets for a couple of Pro-Systems 4150 carbs (one comparable size, one bigger) and both were set up w/ .045" nozzles. - Brad
