Default Re: Fuel pump eccentric

FYI, the 2 different eccentrics were the same diameter and with a different alignment. the small cam gear had 24 teeth and the large crank gear had 48 teeth. So if you are changing the assembly it really does not matter. Since you can no longer get the early 2 gear & chain set you can go with the complete set from the later model. I let the part numbers at the shop but will post them tomorrow when I go to the shop. Thanks to everyone who gave me there intellect, for what ever that's worth. This site is great for people who are not familiar with these motors. John
