Was about 15-13"Hg and when I would rev it up and close till it almost stalls then open the choke it ran normal for a short time (10secs)
Took it apart cleaned with carb cleaner but didn't have my air gun to blow it out. Put it back ran good for a few minutes then got sloppy.
Idle screws do nothing all hoses are connected the port in the back of carb is good
Intake manifold has a leak but does not affect vacuum ive put carb cleaner/water on the flange and idle/vacuum remained consistent, I think its the heatcross over exhaust port.
Regardless it would not affect the idle would it?
Idle screws have no effect
Car has normal vacuum above 1000 rpm
Below runs rough and lower vacuum
The heatriser valve arm bounces back and forth shortly when car is warm
Ive sprayed carb clean down the idle bleed tubes and idle mixture screws but no change
Any help is appreciated
