Sticky Choke

[63larkcustom]

I'm having trouble with Betty when the temp drops below 45. I've made several adjustments on the choke but can't seem to find the right setting. If i set it so that the flapper barely closes when the throttle is pulled out, the car warms up and then starts flooding itself out or running at a very high idle. I've cleaned all the linkage and the carb throst. When its warm if i set it so the engine runs at the proper idle, it refuses to start the following morning. I never had this trouble with my other studebakers. Oh yeah, its an ohv6 with the rbs carb. I remember when I was a kid our local mechanic showed my mom how to use a clothespin to hold the choke shut to get the car started (it was an amc sportabout). Surely there has to be a way to make this thing work. Any suggestions?

sounds like your choke tube is plugged, it brings hot air from exhaust, and /or the heat riser is not working..

Also, unscrew the hot air tube that connects to the choke housing on the carb. Start it up and check for vacuum at that nipple on the carb. If no vacuum is there, the carb. is stopped up causing the choke not to open up, therefore causing a flooding condition. If the hot air supply pipe in the manifold is broken or rotted away, that will allow exhaust gasses and crud to be sucked into the choke assembly. Hope this helps.

You said something about 'when the throttle is pulled out'. Do you have a manual push-pull cable connected to the choke?
