Hello: crank1938

Chances are the carb(s) is gummed up. Only solution is to have the carb professionally boiled out in carb cleaner to clean out the left in gums and varnishes. Than a new carb rebuilding kit of parts installed and adjusted.

Cleaning out the fuel lines, etc will notclean out the residues left in the carb(s). Only internal carb(s) cleaning will solve that problem.
