tacho sensor position

Postby Garyo » Tue Jan 19, 2016 10:33 am

since I had the flywheel off my Jab, the tacho reading at tick over is fluctuating (needle bouncing) after 1k rpm it is stable. I cannot find a distance in any of the Jab books as to the gap for the sensor to pick up should be, anyone know what this should be? or a likely cause other than a possible incorrect gap?

From memory 10thou. It could be that the sensor is on it's way out. I don't use them anymore but when I first got the aircraft, I had a similar problem where it was incorrect at low revs but fine at higher revs. I replaced the sensor and all was well. Paul at Parts4Aircraft sells them and they are cheap.

Failing that, have a word with Dean who has made up a different sensor that is a lot better and works with anything.
