Don't waste your money on the Tiny Tach. I bought three or four of them and
finally gave up. I still have one in the box that displays something, but
it never showed a thing when hooked to an engine. Even if you finally get it
going, it won't last long, and may give you double or triple (or half or a
third) of the reading it should...or it'll just give you some crazy number
that means nothing. The stories are in the archive, and even on my webpage
somewhere, but I suspect you will not be pleased with it or the support
you'll get from the guy that sells it. Yes, I used the correct four stroke
version.
Trust me...I tried very hard to make it work, and when I finally got it
straightened out (I had to shield the coil wraps and plug wire with aluminum
foil which was also grounded to the engine), it lasted only a few months
before it went blank. I'm assuming the battery died. It's certainly not a
7 year battery, at least not if you use it. Put your money into something
that will be accurate and last, and you'll be way ahead...
