Re: Carb rebuild and now some new problems

Well, got out and did some more checking.

1. It looks like the accelerator pump is working properly - with the engine off it sounds like a good squirt of gas is getting pumped in when I operate it.

2. There was one other change I made when I rebuilt the carb - I reattached the purge vacuum hose from the charcoal tank to the carb, which was previously not connected. I disconnected that hose again and capped each end and drive the truck. It seemed like the problem was resolved by doing that - I couldn't get the truck to replicate the symptoms.

BUT - when I got back home the truck wouldn't idle once it was at operating temp - it was reving way high. I went in and turned back the idle screw (not the mix screws) and it didn't help. What could cause it to rev high like that?

I also noticed down by the fuel pump that the larger of the two hoses is pulsing with the engine running - not sure what that's about or if its related...
