Thread: Sudden problem, truck dies at idle and some black smoke from the exhaust

Tweet

Well heres where I lack expertise. It is carbed but I havent put a gauge on the rail. I know the pump is working good, I've just done the fuel filter. This is what gets me. I've been driving the truck for almost a month now in all ranges of temps and it starts right up with no hesitation. So why now something is different I'm not sure.

All the plugs looked pretty bad, I have no idea how long they had been in there but I'm guessing awhile. Then I found that the distributor cap has a gash inside it now as well, it's not cracked though. How I have no idea.

Secondly this is a 750 carb, granted the motor is .30 over with a mild cam I'm wondering if this is to much? Maybe it's fouling the plugs with to much fuel and I'm just looking at it to hard.

I've never dealt much with having to adjust or troubleshoot carbs so this is a new one to me.
