First, do what Junkyard John suggested.

If that doesn't work, you need to spend a few dollars on a vacuum gauge. It will tell you a lot about what's going on. Go here for info http://www.centuryperformance.com/vacuum.asp

Also, I would pop the top off the carb. If there's sediment in the bowl, it needs a good cleaning.

got a guy that is gonna look at the carb this weekend. he says probably has sediment too.
The bad part is, my old minivan's tranny also died this week so Big Blue is the only running vehicle right now. Guess i go the weekend with it.
And, this is the wekend that me and Dmurphy68 were gonna take the old 68 rust bucket up to his shop in Middletown and cut it apart for parts.
Oh well....................

Well, if you had that much rust and sediment in the filter then you may want to pull out the fuel tank also that could be alot of the problem. It also sounds like you may want to invest in a new carb. I run R45T's in my truck gapped at 40" and have had no problems.
