Don't mean to highjack the post, but it seems a sensible place to post my questions which relate directly to the same carbs. If I've erred, please let me know.
So today I "finished" rebuilding my carbs.
I watched the CMC videos on rebuilding CB 360/350 carbs and took a lead from here. There are a few differences between 450 and 350 carbs - e.g. the slow jet screws in on teh 450, but I was able to work this out - clever me!!
However at the end of the process I have a couple of questions, I'd appreciate some thoughts on.
1. On removing the needle jet from the piston, a small (tiny) washer also fell out.This does not appear on the diagram in the Clymer manual I have. Is it necessary?
2. The float height according to Clymer is 20mm. According to CMC, for the 350, it is 23mm. Mine were set at 23 +/-. What is the correct setting?
3. The piston moves freely up and down the carb body, but when I put the top on (cylinder vacuum) it becomes a bit sticky. It will move up easily enough, but doesn't immediately drop back down. Is this OK, or do I need to do something to make it move more freely?
Thanks for your thoughts.
