one screw has to be turned all the way in for it to idle right, four corner 4150 holley.
do i have a clog or something going on there?



If I find one like that I use carb or brake cleaner
with the hose on it and blow thru the mixture port
are you pull the screw out.. some times I have to hit
it with the air hose... then try the mixture again
