    Will a standard automotive style tach work on a 2 cycle engine?

    I'd say no, You have to be able to tap into a coil out-put lead (not plug wire). All you have is a kill lead off the coil on newer small engines.

    That looks cool, but no. I was thinking of the little handheld unit that you use for tuning the carb.

    Something like this:

    It should work but you may have to do some math on whatever numbers it spits out. I forget as I have not used the tach that came with my Fluke in quite some time.

    this one is quite expensive but I use mine for many things. you can check anything that spins with the photo mode for non contact reading of you can use it to measure belt speed and contact rpm's. It is a very useful tool. I am going to get a benchmark reading for my deck pulleys and belts to make sure all is running peak, without just wondering if it sounds like it is down on power.

    I love my SnapOn tools, but I've had my TinyTact for as long as I can remember and it works great, like the old Timex watches.

    :laugh: I guess if you have the toys, ya got to play with them :rolleyes:
