I would of course suggest to do the full process on www.tuningmadeeasy.com.

But my guess is also carb more than ignition. Above 4000 is secondary circuit, that seems to work fine, but primary and idle circuit (idle circuit contributes all the way up to 50 mph) seems to be the problem.

First, check for problems. Take the carb off, and look inside. Any dirt clogging anything? Powervalve smooth? PVs are a terrible invention, they can burst, but they can also just harden, then the calibration is totally gone. Test it by pushing it against another PV of the same vacuum, they should move evenly, like a mirror. If nothing wrong is found, adjust the carb, as per my home page. Yes it takes time, but it gets you there instead of keeping on guessing.
