2. The Insulator was wrongly installed with the small cell facing the Intake pipe, instead of facing the air entrance into the carburetor.
Now that the correct parts are reinstalled in their correct orientation, RPM is back again to 7,100 with APC 19x11" and Morgan 30%, and 6,800 with Morgan 20/20.
Thank you all for the sympathy, and always check twice!
Thanks for the update.
I just pulled the back off mine for a look, and to check how my storage method is going corrosion wise. You might just tempt me to get mine going properly again too.
