I read throught the attached manual, and I have already done most of those steps.

I called and asked the guy at the Carburetor Shop about a Carter W1, and he said that was for the 216, and I will need a Carter YF, althought he is sold out presently.

He said there were different models of the YF, and there might be a link here on the forum that would help me match one up for my 235.

I looked on the for sale forum, but did not see any for sale.

He said my two months of tinkering and not much progress is typical with the B.
