Ok, I have taken out the fuel pump push rod(440 CID) and its 1/16th of an inch shy of the given length of 3 1/4 inches. Is that enough to not get fuel to the carb. because if its not, the lobe on the cam may be gone cause it's a new fuel tank, sender and pump(it sat 17 years and what a stinky mess). Is there any way to check the lobe without pulling the cam?
