Also how would you mount the fd-478.


I had this happen and it was the tach causing it. Took forever to find it but got lucky one day and saw the tach acting weird. No problem in 6 years since replacing it. Easy test just disconnect the tach wire on the msd box and see if it goes away.


so would you go down the track without a tach??? i don't think i have a spare tach sitting around.
