When does the carb pop during engine compression?
Popping/crackling through the carb during acceleration, cam, compression, or what? Discussion in ‘ Engine Topic ‘ started by Penix, Feb 14, 2009 .
Why does my carburetor make a popping noise?
Popping noises from a carburetor indicate a form of backfire. Too much air and not enough fuel causes backfires to occur in the intake manifold. The exploding mixture then vents through the carburetor.
Can a vacuum leak cause a CARB to pop?
A vacuum leak can cause what you described. I would get a propane torch and with it unlit of course, check the intake manifold and around the carb for vacuum leaks while the engine is running. If you hear a sudden change in engine idle, thats where the leak is.
What to do if your carb Pops during acceleration?
May need to remove the rockers to get a good indication though. Then just remove all the spark plugs, put a breaker bar on the balancer and turn the engine over manually to check it. Hope this helps!

Why does my Eddy 1406 carb keep popping?
I’ve checked the timing and that’s fine, I’ve even swapped carbs (from an Eddy 1406 to a Holley 3310-3), but the popping persists. So I’ve come to the conclusion that this must either be a compression issue or a cam issue, or something else I’m just not thinking of.

Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

How does the PCM control the idle speed?
The PCM monitors idle speed and operates a solenoid or small electric motor to move a valve that regulates airflow through the air bypass circuit. If the ISC valve is gummed up with fuel varnish or dirt, it may stick, preventing the engine from maintaining the proper idle speed when the throttle closes.
