So its time for a carb rebuild on the 350X. The choke valve plastic knob on top has cracked in 2 pieces making it unusable, of course its discontinued like everything else it seems. Looked around for used but no luck and anything out there is around 35 years old and likely to also have the same fate soon. Is there another similar keihin/honda carb model that uses a close choke setup anyone has found? I wouldn't even mind converting the lever setup to button type also.
