Hi All,
When I first got my MKIII it needed carburetors. I bought the Wassell EVO carbs and began installing them. Right off the bat , one of the removable pilot jets was supplied with metal swarf in the orifice-- that could not be dislodged. The seller kindly sent me a new jet. One of the throttle springs had flakes of plating stuck all over it --similar to a flocked Christmas tree--and I chose not to use it and used one of the old springs instead. This is sloppy QC, but I figured that they would probably work. But over the long haul, at idle , I could never get the right side to feel as solid as the left when putting my hand behind the exhaust, no matter how I adjusted cables or screws. Then the left carb tickler kept sticking. I finally took it apart and Wassell uses a steel washer at the base of the split pin that forms the plunger to depress the float. The taper on the flared end of this split pin was just right to wedge into the washer and jam solid with engine vibration. To top it off, the ends of the split pins are so sharp they have started to dig holes in the floats.
To sum it up--I am a novice at tuning and I started to feel that I did not need the fundamental quality of the carburetor being a question mark--and I feel that I could never trust that I was getting the best out of my bike with these carbs, even if I fixed all the overt defects.
I just got the Amal Premieres lashed up on the bike this evening and right off the bat I got a stronger left side idle than the right and the transition from idle to driving in first gear is much more solid and predictable. I have much more to learn regarding optimizing these new carbs but the omens are promising.
Very Sincerely,
Kara
