thank you again for positive feedback
one last question being, what modern carburetor would you suggest?
The 1901FF IS a modern carburetor.
If you are asking about a "new" carburetor, you are going to need a carburetor guru to re-calibrate ANY new carb that you buy, as the I.H.C. calibration curve will differ significantly from anything you can buy.
Repeating one of my previous posts, the 1901FF is a good carburetor. It may (or may not) have a problem, but if you do your tests, you will find the problem.
(Opinion) If your carb dude is recommending a "new" carb, I would suggest a "new carb dude".
I might also suggest burning out the fuel you have in the tank, and try some of the lowest octane fuel you can buy at a "name-brand" station. Your engine does not have either sufficient compression or sufficient static timing to burn the premium. This just might be your entire issue.
