Was wondering if anyone has ever resleeved the slide bore of a carburetor. The Amal concentric carburetors were used on vintage British motorcycles and, in fact, they are still available today. The problem is that they are made from a relatively pot metal (not aluminum). The slides are made from the same soft material. The result is a galling action leading to wear which leads to improper fuel mixtures. I would like to ever so slightly over-size and true-up the carburetor slide bore. The slide would be turned down and a brass sleeve affixed to the slide. My thoughts were that a reamer would do a more exacting job than trying to bore on a lathe. An aluminum cylinder with simple steel cutters set in the cylinder should do the job with perhaps a center shaft protruding into the needle seat hole to ensure alignment. This entire operation could be done by hand and a reamer would provide a cleaner finish. As for turning down the slide, I haven't come up with a more simplified technique Both the bore and slide are round of course. If it were only one bike I might take the plunge and buy a set of the new Premier Amal carbs. They, like my effort have a dissimilar slide but with several vintage bikes the cost begin to become prohibitive. I thought it would be worth the try as i have a couple of worn spare carbs to experiment with. There used to be a few old chaps around that did resleeving but they have taken their secrets with them.
Any ideas and suggestions would be much very appreciated. Thank you
