Thanks for the suggestions. I will play with idle mixture screw to see what happens.
The carb has new gaskets with the exception of the throttle body to the fuel bowl. The one in my kit was distorted. I should probably get a new kit to play it safe, I am doubtful of kit’s quality and age. I did not soak the carb, I just disassembled and blew out the passages.
There is booze in the gas in my area. I am not certain what percentage. I believe it varies with summer and winter.
You probably did all that was necessary. Soaking should not have been required, if you blew compressed air in both directions in all passages.
Try the idle mixture screw first. If that doesn't fix the problem, it may be necessary to borrow an exhaust gas analyser to determine if your mixture is too lean or too rich at idle (either will cause the hesitation).
Jon.
