I will refer to my last post on your other thred when you concluded it was a vac leak

I said a "burnt valve"

leak down test is in order along with a valve job

so...am I right now?





Ok ok ,I stepped on my d*** when I concluded that it was "only" a vacuum leak causing the issue.

It ran much better after I tightened the carb,so I thought I had the problem licked.

I then remembered about the compression test and figured I would cover all bases,which is what I should have done in the first place.

So now I know the truck runs "better" because I fixed the vacuum leak,but the truck has ALOT more improvement in it once I get the valve issues repaired.

I apologize for saying it was "Only" a vacuum leak causing the problem when in fact it was a burned valve issue as you suggested.

Again I thank you for your suggestion and hope I ruffled no feathers for "jumping the gun" on my diagnosis and concluding the problem was something other than what you had suggested.
