Reply to "Mangusta Engine Removal and Rebuild"

Mike, if the tach is only "wrong" but working, it could be that just turning the trim pot in the Tach brings you whole...the tach/speedo are easy to open up (unlike the 2" gauges),  the guts are not fragile or uncommon. It seems that some others just suffered noisy battery voltage to the tach (so a big cap on the Battery line right at the tach just might help, even an inductor/capacitor there). Since the tach triggers on that high voltage spike, its hard to know how an external resistor or capacitor on the Tach line will do much, but who knows...

...and then comes the paint and body?
