Thanks for that clear and confident assertion AV.

Keep after that regulator lever adjustment, it is critical.
Good. That confirms my suspicions.
You might also have a look at the high speed check valve in the carb
I cannot find one of them in my model. The only reference that I have is a .pdf doc from Walbro for the WB model. They advise that it is (quote)"almost the same" (end quote). Manual for the WB model attached above.
You might also beg, borrow, steal, or make a pop off pressure checker and do a pop off pressure check.
I don't know how to do that. I will have to make one, do you have any suggestions of how I could make one? I am guessing, a low range, accurate pressure gauge (maybe a good tire gauge) and a relief valve etc.?
Edit: Last thought..... You are putting the regulator chamber gasket on first, and then the diaphragm on top, then the cover right? Lots of people put them on backwards, then have "too rich" problems.

Affirmative!
Many thanks for joining the discussion with helpful information.
