I had to install some new float valves in my carbs on my old CB 750/4.
Whoever was messing about with the carbs prior to me had bodged the threads on all of them to some degree.
I looked at installing heli coils, but at a cost of $86.00, for 8 helicoils???
thinking again was an option I followed.
My neighbor ( an old english bike restorer) told me to use a national coarse, or Whitworth thread 3/16 of an inch.
It cost me $2.50 for twelve Allan head cap screws 3/16 x an inch.
I did not even have to drill out the old threads, just straight into it with the 3/16th tap.
The locating dowls I had to drill out slightly, and I made paper gaskets.
It took me a couple of hours, but I ended up with a perfect job, and a coarse thread system that will last.
Just thought I would pass it on.
Also I am looking for a disk and rotor/caliper for the old CB, and a oil tank side cover for a F2.
Any info is appreciated.
