Just a follow up to my last reply that after relooking at the YF 2101S throttle body I have. It appears that the throttle linkage arm is unique to the YF 2101S and isn't usable on the YF 2100S. There is no mechanism/arm connection to the manual choke plate rod assembly to the upper section of the carb. Sorry it seems it won't work out. frown
