Just thought of something else, you have 1/4" holes in the plates, I wonder if this is too big and effecting the t-slots. What I mean is, since so much air is going through the plate instead of having high speed air going by the t-slots, I wonder if this is why the fuel is coming out in blobs instead of atomised, which caused you to turn the idle up, which made it worse, so you turned it up more, etc, etc?
Try plates with 1/8" holes and see what happens, you might get some vacuum back and it might clean up the idle so you can use the screws/lower the blade angle closer to the t-slots. |

When I was involved with that, the cams came straight from the catalogs & dwell cams were unheard of. #'s ? too long ago.

The local Cleveland guru we had around here in the 70s always used Schneider cams. It might be worth giving them a call and seeing what they have to say.
