Hi guys - my 1980 CB750F sat for about 12 years before I bought it. It's a pretty original bike including the factory carbs. I pulled them off to rebuild them, but just for grins actually ran the bike briefly off them and it ran surprisingly well but #2 carb was overflowing like crazy.
I rebuilt them using the kits from 4into1 after checking the floats were still floated and didn't have any holes in them. I used new float valves (that shut off and installed them properly.
Got them back on the bike and it fired right away and ran great but then I got pretty bad overflow from #1 and #2 this time. I did NOT soak the bodies in cleaner, and am wondering if there is crud where the float valve seats are that is preventing them from flooding. Any thoughts on that or other ideas?
Thanks!
