I have a six cylinder gas engine in an old loader. Well, maybe not old, it is only 71 years young. Anyway, it has no governor, and I would like to put a tachometer on it. Most of the tachometers are zero to 8000 RPM. Since this engine is not supposed to be used above 2500, I would like a tach that is for lower RPM. One way to do that is to have a tach for 3 cylinders on a 6 cylinder engine so it reads double. These seem to be rare and expensive. Anybody have any good ideas for a tachometer which either has a much lower scale, say 0 to 3000, or one for three cylinder engines? Is there some easy way for a dummy like me to make it read double? I really don't want a 0 to 8000 tach that never sees anything above 2500, partly because it is less accurate and harder to read.
