hi, I have a 1976 f-250 ranger. it has a all stock engine (rebuilt in the 90’s so it’s not all worn out from 30+ years of work). When I have it operating temp, and let it idle down for lets say, as long as it takes to sit at a red light (a min, or so) when I go to step on it to take off it stumbles until you get up to about 5 mph or so. Here’s the catch though, if I pop it into nutral and rew it up a few times right before I go to take off it does not stumble when I step on it. Any idea how to fix this? thanks. ---

I am not a real carb man, but I suspect your problem is at the carburetor. ---

yes, I think that might be it, it has had three carbs on it since the rebuild. I just need to know how to fix it. ---

Possibly the fuel pump can’t provide enough fuel to the carb at idle, then when you take off you are lacking fuel to the engine. I suppose you could narrow this down by seeing how it reacts at a stop sign, where there isnt enough time for the fuel bowl in the carb to run dry.
