Some of us are sitting on the fence, just waiting on a push.I WANT a tach. I just haven't seen one I thonught was a good deal yet. Oh, & I have done the "consider the cost of a rebuild" It's just the typoical longevity of the engine convinces me I don't NEED one as bad as I want one. So, I NEED a good deal before I can justify spendin the $$. I wonder where I could get a used one? Can an automotive tach be used at all? Would I have to multiply the reading by 8?
Oops, I changed the photo, but it gets distorted in the message. Is there a code to set the size of the image?
Anyway, my bad

I bought my tach second hand from a guy in the Be_Savage group about 3 years ago. I think that he paid about $80, tried it, didn't like it, and then sold it to me for $50...so I'm sorry, but I can't tell you where he got it.
I think that he wanted a different size or something, but for me it is just fine and works great. All that I got with it was a lousy set of instructions, not even a manufacturer.
