With the engine off, eye inside the primary of the carb, move the throttle, you should see 2 streams of fuel spray into the venturi`s, if it sprays none, or delays then sprays the problem is the accelerator pump.

if the acc.pump is bad how will it idle in park and rev easy?

 

[DoubleVision]

Acc pump has nothing to do with the idle, the idle circuit does.

will idle circuit adjusted wrong cause these problems
