Two problems solved, only to have two more pop up??? HELLLLP

If you can't get rid of dieselling, until you sort it out you could try to rig up an Idle-Stop Solenoid. This setup was OEM on Z28 Camaros and 396SS Chevelles in late '60s, early '70s when high performance engines met emission controls.

 

The solenoid is actvated with ignition switch "on" and the running idle speed is adjusted by turning the hexhead rod that comes out of the solenoid and contacts the throttle linkage. The usual idle speed screw is backed way off. With the solenoid unplugged, the usual idle screw is set so that the engine won't idle anymore and dies (like 400rpm). With the solenoid activated, you can set idle at 800rpm and when you shut it off the throttle plates snap nearly closed and this prevents the engine from dieselling. Maybe you could find one of these in a JY, I think GM used them extensively even on economy cars back then. DAW

I've been thinking about that DAW. I've been trying to figure out what would be a good way to set it up with both carbs. Also I'm gonna talk to a friend of mine who knows a bit about old domestics (more than I do, at any rate!!) and see if he knows where would be a good place to look, and maybe a good way to set it up when I get it.

 

Tim I don't think I'm doing anything, I'll email you when I know for sure. It would be nice to get another opinion.

Well, tried colder plugs and no luck Also tried running some Marvel Mystery Oil thru the gas... I'm starting to run out of things I can do to solve this problem
