I would like to get a tach for mine, but the autometer is around $250. Thats quite a bit to spend why you really don't get added performance. If you Know of any cheaper ideas on tachs, please send them my way also. I wish a car tach would work. You can get a nice one for a good price!

 

"The answer is left as an exercise for the student."

Unfamiliar with your specific machines, I hope enough clues are provided for you to find the answer yourself. (Hint: Does your ignition system have points, broken by a cam rotating at half crankshaft speed? A pickup coil sensing a mass on the alternator rotor?)

A Tiny Tach/Hourmeter retails around $ 40.

Bought the standard tiny tach (without the reset button) yesterday at the local lawnmower shop and installed it last night with no problems. It is working fine on my four stroke engine. Thanks to everyone for the info.

 

Phil,Can I ask you a favor to post the part number or model of tiny tach you bought?This way I know which one to get.Thanks in advance

 

I'd be glad to. I'll post it as soon as I get home this afternoon and get the number off the bag.

The part number is - Briggs & Stratton 19389

 

Diogenes,

My Tiny Tach reads around 1800 rpm at idle. Given that my Bayou has CDI ignition, I suspect the true idle speed may be around 900 rpm since I purchased the four-stroke tach. Of course that assumes the Tiny Tach made for four-strokes is showing a rate that is twice the rate of spark.

With that in mind, the two-stroke unit would actually work correctly on a four-stoke that fires upon each revolution.
