perplexing problem
brand new AED 4150 carb
set floats and pump shot
initially I had a bog from standing start.
changed cams and shooters (BIGGER)
second road test:
stomped the throttle and spun tires through first into second.
next day
warm car up to temp as before.
step on gas and bog is back???????
took off pump arms and bent the arms a little.
readujted accel pump for .015 at WOT.
ok back to smoking tires!
next day same ol bog again?
this got me scratchin my head?????
maybe bigger accel pumps ????
