Another thought, it sounds like the electronic ignition is new as well. Have you thought about or tried putting the breaker points back in and seeing if that changes things? Which kit did you put in, or did I miss that in this thread?
Edit: rereading, maybe the ignition change was one of your tries at fixing the problem and happened after the problem already had started. In which case, disregard my comment entirely. |

Just ordered gaskets and planning to check spacer and other surfaces for warping when apart. Thank you!
Will post an update after install.

When you swapped the carb , did you verify that the carb linkage is the same and provides the same throw as the old carb? What I'm getting at is do the butterfles go to wide open with the throttle is wide open.
Also, check the torque on the carb flange bolts. Overtightening can cause some warpage and vacuum leaks that will make the engine run poorly.

I will boldly go out on a limb here and predict that Rich solved his problem with new gaskets above and below the spacer.............mostly because he told me that it was fixed after the gasket changes
 The spacer to manifold gasket was kinda ugly.
Any more details will have to come from him.

Well, here is good news. Removed carb and the riser under carb. Gasket between riser and manifold was broken and apparently leaking .Replaced both gaskets and all runs well. Still doesn't make complete sense to me but I like the end result. I would like to thank everyone who helped along the way to a solution...
