I'm just installed a Stage II Quadrajet from Jet and don't know why they didn't change out the Thexton idle mixture screws with slotted ones?

I'll let you know once I get the car started. I had a 50% chance to find the compression stroke of cyl 1 when I dropped the distributor in because I did not have the valve cover off or my finger in the spark plug hole. Of course Murphy found me and I founf tdc of the exhaust stroke, so I have redo it once the wife gets back home to watch the kids.

I guess that I jinxed myself with my original comments about “all carbs are great”. The Stage II 750 CFM Qjet had a stuck float and nothing good can come from that. I borrowed a 600 cfm Edlebrach carb from a friend to get the car running. I think that the 600 cfm carb is too small for my olds 403 that has ported heads, performer cam/intake and flat top pistons (turns out that I got flat top pistons after all and not the dish ones)… Also should note that I’m running 2004r with 3.73 rears. Nonetheless the car still goes like a “raped ape”! I’m going to have to figure out how to get that Qjet running because I think that the 750 cfm will be better for my combo.

I kinda had a feeling that there would be some kinda problems. I think its something you have to worry about when getting stuff from big companies like that.

If you want to take another shot with a Q jet, try Sparkys. They build the carb based off of your engine specs, so it will be a perfect match. I have heard nothing but great things about these guys.

I have the same carb and have ran it for a year and a half now and I think it is really good. Performs well and saves me a few bucks at the gas pump.
