The tach on my Spitfire is going crazy. No change in engine speed, say 3000 rpm, but the tach needle will spike to over 6000! I thought it might be a kink in the cable but not so. Maybe a lack of lubrication? What is the speedometer and tach cable lubricant? Motor oil is not the answer... it seems to get gummy. T.T.
