Got my new carb yesterday. Went home and installed it. It runs GREAT. Just off idle response is terrific, no more black smoke, certainly better than my bad old B. I am having a problem with the choke. The YF did not come with any bracket for the choke/throttle cables. I pulled the bracket off the B and with a little grinding it fit on the carb. I cannot get the choke to fully close(Open?). The choke plate will not rotate more than about 20 degrees. It looks like there is a rod that goes from the throttle linkage to the choke linkage and this is keeping it from working properly. I won't be able to look at it again until tonight, but I'm searching for any ideas or experiences.
