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.
