Aaaah... sounds like you have worn throttle shaft bores then. I had a Buick Quadrajet on my 355 with that issue and I could never get it to have a consistent idle because the throttle shaft would hit the set screw in a different place every time. This is a common problem with old carburators and can be fixed. The throttle shaft bores need to be reamed out and fitted with bronze bushings. One of my Quadrajets ( from a Cadillac 472) has had this done at some time in it's life. Mine has not, but I searched for months for one that had tight shafts before pulling it. It can cost $50 or more to have it done by a competent carb shop.
yeah see I'd rather rebuild it myself or just buy a new carb lol.
Then you need to buy a kit to re-bush the throttle shafts. I think that Summit sells them and so does Jet and a few Quadrajet specialists. For me, it was just simpler and cheaper to get another carb since the Buick Quadrajet I had used the straight in fuel fitting and not the 90 degree one typically used in a Chevy application.
i'll have to take care of that later.
I was under the car putting mufflers on...and I noticed that the long bolt originally connected to the oil pressure gauge is too long and the header is hitting against it. I bought a bolt from the hardware store that seemed to be the right thread to plug that hole but for some reason it just would not thread in there. we found a bolt (at the hardware store) taht would thread properly on both bolts though. so i ended up plugging the end of the "oem" bolt with a smaller bolt.
i looked at summits plumbing section and the have plugs but I just dont know if any of them would work. do they not make plugs specifically for this??
btw the mufflers sound good but there is alot of resonance in the cabin, probably because they are bascially right off the header extensions (under the seats). I will run more piping one day...but...yeah one day...
