I have a 1976 FWC engine with reduction drive, electronic ignition and indigo crankcase ventilation system. Engine starts easily,idles at 650 rpm, runs smoothly but lately I have been noticing a constant vibration in the analog tach pointer, when I look at my digital tach it shows that the engine speed is constantly varying plus or minus 20 rpm. This is at all speeds.
Am I being a hypochondriac? is this a problem? IN the past the engine rpm has been rock steady.
Any thought on causes. I was thinking that one of the valves might be sticking
