Thanks for the info,
So you don't think it's carb vacuum problem but a mainifold (engine)vacuum leak?
Would it help if I plug all the vacuum ports, including brake booster, pvc etc., coming off the engine and see if runs any different? Should I also plug all the carb ports except the dist?
I do get a hissing sound under the dash, but it comes from the heater/AC controls. It hisses if the lever is in any other position other than the one with the "downward arrow" and that where I keep it.
As for intake gaskets, i replaced them three times with different style ones (baffle and strip) and it didn't make a difference.
Also, how much hp do you think my combo makes, and what kind of e.t. could I expect?
Thanks for the info!!!
