Thank you,Tim

Choke cam is stuck
Or
Vacuum leak??

[bhill86]

Or timing already advanced really far?

[Scott Thelander]

Sounds like he only worked on the carb
But
I’m sure he’ll reply back

67 Carter 4bbl. carburetors use some unique gaskets between the carburetor base and the intake manifold. This includes a stainless steel shim gasket along with the paper one to close off the carburetor heat passage in the intake manifold. You must have the correct gaskets for a 67 model or you will have a large vacuum leak and a fast idle. Be sure all that is correct. Your rebuild kit may not have included all the correct gaskets and the sheet metal shim .

Thank you guys,actually I've been trying to get this car running right for a long time. new hei dist ,electric fuel pump, 11 bolt water pump,dual electric fans.
I removed the manual fuel pump. A bit overwelming,does anyone know where I can get a correct rebuild kit or maybe someone to rebuild it.Sorry about the rant but thank you guys for all you're help always a great bunch of guys.

Does this carb have a large brass screw, front centre? If so, it is for idle speed. It controls AIR & acts like an air leak. Screw in to reduce idle rpm.

A 67 GTO would use a Quadrajet (mfd by Carter).

My bet is that the stainless steel heatshield to throttle plate, on flange gasket, is missing.

Thanks Geoff and Kenth,would a vacumn leak to the pwr brakes cause this?I'm not at the car now,but will look for that brass screw tomorrow I don't remember a brass screw.Thanks again guys.
