With the right adjustments & the carb in good shape the choke should work good. First make shure there are no vacuum leaks. Check the base gasket & make shure all unused openings are capped off. Adjust the idle jets by turning them in slowly till the engine starts to slow down, Then back them up till it runs smooth. There is a screw on the pass. side of the carb that adjust the fast idle speed. You have to have the engine off & open the throttle to turn it.The choke plates should close up all the way when the engine is cold. When you start the engine the choke should open about halfway by the vacuum choke pull off. The tention should stay on for afew minutes & gradually open due to the electric heat in the coil. If adjustments dont fix it you may have to ohaul it. The float level could be low or the metering rods stuck. Be shure & don,t leave the key on without the engine running when it is cold unless you have a choke switch. The choke heats up & goes off too soon. The manual choke kits are junk.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
