I know what you mean with about worn body's and slides. i haven't seen it too much with Mikunis although Ive got a TM 36 here thats sloppy as. theres nothing worse than trying to tune a engine with a worn carby. its impossible. i see it all the time with the Amal carbs. very poor design many/most use a alloy slide against alloy body (same material) they wear heaps and you cant tune them properly. its gets to a point where we tell the customer theres nothing more we can do except to repair or get new carbys. the ones with brass slides are just as bad. so the solution is a resleeve or a new carby/s. we haven't had any resleeves done for a while. many of the real old ones with brass slides can get away with a new slide, but the alloy on alloy ones need to be resleeved or replaced. some guys with the 70's bikes don't mind upgrading to a mikuni but many want the original type Amal. thats no problem as they are available. unfortunately they have not improved their design. but with really old bikes a mikuni just looks stupid and is out of place so a new correct period carby is fitted or old one resleeved. its usually a toss up weather or not to resleeve or replace as price is roughly the same. many of these vintage bikes are just weekend or show bikes and don't get ridden real hard and its just a piece of history for the owners and they are not out there to go fast on their ancient British bike so don t need high performance carbys.
anyway heres a few pics of the worst of the 4 i did. i was very happy how they turned out. it looks better in real life as you can see the shine a bit better. these mikinis are in pretty good nick and are well worth the effort for me to restore and are not ready for the throw away basket yet. if the screws are butchered i will replace with new ones otherwise they will get gold zinced along with the choke levers and other bits
