part 1part 2Hello all!
should've been called carb ovefrflow diagnosis...
reminder: not for the stock carb, for a mikuni VM 38.
anyway, I tried adjusting the float from 20 mm to 16mm... still overflowed.
Finally tried removing the vacuum line, and capping the vacuum ports on the carb and petcock with 3/16" (I think that was the size) vacuum caps. Seems to have worked. No more overflows in several hundred miles. Rough/eratic idle, need to readjust the float height and get the pilot circuit dialed in.
So, anyone having a similar problem and the needle valve
is working, you might try my solution.
Best to all and Happy Thanksgiving!
