Unfortunately the Taiwanese O-rings for the float cups seem to grow in size. I think I read something similar about the Keyster kits (brass parts OK, rubber parts NOK).
Float height should be 21mm. The Haynes manual is incorrect as I found out to my cost when the carbs overflowed! Thanks to the helpful people on the forum who know the correct measurement.Sounds like it's going well though.

I think I read something similar about the Keyster kits (brass parts OK, rubber parts NOK).I know various people have had a bit of fun fitting these O rings when using the Cruzinimage kit as they are not shaped.A dab or two of sealant to hold various points in place seemed to help, and I seem to recall warming the rings to help soften them may also have been mentioned.
I usually treat the o-ring getting fuel on it making it swell as a sign that the fuel level is too high, As the fuel level should be lower than the bowl mating face, in an ideal world we shouldn't need an o-ring. For this reason I rarely replace the 0-ring.
I do remember reading that float needle valves in some of the aftermarket carb kits have a slightly different overall height than the originals. That would certainly affect float level. For that reason, I used the original needle valves - which had next to no wear - with my new carb kits.Regards,
