I need to get myself a tach.
To be used on my older Tecumseh, and Kohler engines.
So far I've been winging it, but it's time to get more accurate.
What should I buy?
Thanks

Thats a Tach? Looks more like a twist off bottle cap opener. No blinky lights.
How's that thingy work?

It works by measuring the frequency of the engine vibration. Somewhere on here there is a thread on using one so if you do a search you should come up with some info. I use an optical tach. You put a small piece of adhesive backed reflective tape on what you want to measure and point the tach at it to get a reading. If you look at the photos in my recent 314 engine post in the JD forum you can see the reflective tape on the PTO sheave. I need to engage the PTO to use that. I also have a piece on the drive shaft and can get readings from either side of the engine if I am working on it to set the max. speed, idle speed etc. Actually heres a picture of the PTO

A sticky at the top of this forum. Hmmm

The best one I have used is Design Technology Inc.'s Tiny Tach. Easy to setup, use & read. I will not use any other tach. Welcome To Tiny-Tach. Small and economical tachometers for gas and diesel engines.

i use a stewert-warner hand held one here, got at an auction for $25. It read 0-4000rpms, in either direction. You just hold it to the end of the turning shaft.

I have a "vibra-tach", and recently got an optical like JDBrian has. The vibra works great, but the optical is much more accurate. If wanting one to stay on the tractor, then "Tiny-Tach" is the easiest to mount.

If you already have DMM with RPM capabilities all you need is is the pick up to clamp to the plug wire. Just remember a lot of 2 cylinder engine fire twice, top and bottom of stroke, during each Revolution. In that case you could use the 2 cycle setting or divide the reading in half.
