Anyone try using the Hatachi built HS6 from a Datsun on a TR motor? I
loved the ones I had on my Z.

leaking H6 carbs is one of the main reasons why many of us are using HS6
carbs.
I am reluctant to even rebuild H6's for friends because they are
probably
going to leak.
Dave hagenbuck at TRF has O rings to replace the cork gland washers that
he
says work.
The jet bearing is not replaced when they are rebuilt; it is not part of
the
rebuild kit. It can get out of round by years of the jet rubbing
against it
when the choke is pulled on and off. If this has happened the cork
washer
won't seal.
