Ultimate carburetor rebuild kit with floats for certain Honda CB350 & CL350 twins from 1970-1973. This is the most complete kit available for the 350 twins! Comes with everything shown. It even has both types of air mixture screws that were used. Check the list below for jets sizes. This kit comes with a shaped float bowl gasket and passage plug made of high quality Viton rubber so it will not swell after coming in contact with fuel.

NOTE: Be sure to check your carbs to see if this kit will work for your bike. This kit works with carburetor models 3D, 722A, 726A & 728A which were used on engine number 1065279 and later.

    Almost frustrated

    Posted by Risto Järvinen on 27th Jan 2024

    Very slow service from USPS, because package was missing about 2 month in California. Seller made request when informed by me. In product, there is some differences in dimensions compare to originals. Some too tight jet o-rings and loose jet tubes to carb body. O-ring in airscrew is also littlebit too large. Hope those do not give any troubles for engine running…
