Mike:
A quick check only shows one dizzy drive gear for the tach. Is
your tachometer trying to tell you something (e.g. your car is *slow*?
Bwuh-hah-hah-haaaah! Couldn't resist.).
What makes you think the tach is low? Do you have a dwell or
other meter to compare it with? If you are checking it against MPH,
could your speedo be off or your diff gearing be non standard?
There ARE two different tachometers for the TR6 - one for North
America, and one for the rest of the world (the PI tachometers). Since
the PI used a different dizzy than the NA TR6s.... Is it possible that
you have a PI tachometer?

Subject: Tach drive gear
I recently had the tach cable seize. This resulted in the distributor
drive
gear eating the tach drive gear. As there seems to be no availability
domestically for the gear.
I bought a used 22D to obtain the part. While I was at it I took the
tach
into a local speedo shop for service. Now that I have it back together
my tach
reads 1000 rpms too low. The speedo shop calibrated the tach to 355to1
as
indicated on the tach face. Is there the remote possibility that there
is more
than one gear ratio for the tach drive? I installed a new tach cable and
lubed it
generously and checked routing to eliminate the cable as a possible
culprit.
