I know I've asked this before but I am still not able to figure this one out. I have a 1973 8hp briggs and stratton lawn tractor engine with the old mechanical points and condencer. the factory magnito was broken and after comparing prices I found out it was cheaper to go buy a new stock chevy style 12v coil and ballist resister plus then I got a higher voltage spark which means a cleaner burn of the air/fuel mix and a better running engine. but my problem is now the engine wants to run a higher rpm than the factory maxium rpm's so I want to hook up a tachometer, but all the automotive tachometers in my price range only work with 4, 6, and 8cyl engines. So I need a circuit to make the tachometer think the one spark per one full rotation output of the engine is acutally 4 sparks per one full rotation.
Can any one help me by making a diagram for a circuit that will work for my needs, Please?
Thanks in advance,
John
