Hi all, I've got a question regarding my tacho; '67 Mexico, Smiths gauges. After some at times unreliable running, my mechanic has fitted the Bosch kit to convert my distributor to electronic ignition. The car is running great, but the tach is not functional since the conversion. I know many of you have dealt with this before- would appreciate tips! Does the tach need to be converted somehow as well? Thanks Remi
