I have tried two carbs on this truck in the last two days. Both have just been rebuilt. Both squirt gas when I work the throttle. Both have the float set right. I'm now convinced this is not a carb issue because changing the carb does not change the symptoms. I've adjusted the timing up a little with no luck but will try that again tomorrow. I've rechecked the point gap. I sprayed stsrter fluid around the carb base with no change in idle.

Would a wore out dizzy cause the stumble?

Or vaccume leak?

Bad intake manifold gasket?

Bad cam? (please no, please no, please no)
