Re: Rev counter
Has it been like this for a while or did it start following some recent work on the car ?

Different ignition system fitted? Tachometers work on ignition pulses.

Re: Rev counter
I always have to tap the glass to get my rev counter working. Have done so for years.

Thanks for your input will try your suggestions
Re: Rev counter
Probably not provided much for you to go on Tom. Intermittent faults like this are always tricky. I suggest checking all the wiring connections. If it is just a sticky needle in the instrument you could look inside, but perhaps best left to a specialist to overhaul the unit.
Speedograph Richfield have done similar overhauls of instruments for me.

Re: Rev counter
I always have had to tap the glass too. Needle stop perhaps magnetic?
