I have 3 motors that have the Rochester electric choke system. 2 quadrajet, 1 mercarb.
I recently tried to add an electric choke to my 454 RV qjet and I just couldn't win.
After 30 seconds, the choke blade opens up 1/2 way, and the motor falls flat on it's face. Add more tension to the electric choke, and it bellows black smoke out the exhaust. Any less tension, it dies sooner.
I adjusted the idle mixture screws with a vacuum gauge. The RV runs fantastic when it's warmed up.
So to end this nonsense, I rigged up an manual choke today. Now the RV starts and idles great.
I don't know what I did wrong, but I couldn't fight this one any longer. We want to use the RV and I'm tired of fouling plug trying to start it.
I might continue my adventure when the RV sits during the 120° days, but it's on the back burner right now.
Does anyone have suggestions? I'm not new to qjets in the least, but this one has me stumped
