Measuring RPM's
 

:bigthink: Forgive me for sounding dumb...what tool do you guys use to check rpm of motors? Bear in mind, I have basic tool set in my garage, hammer, sockets, flat wrenches, screwdrivers. :biggrin2.gif: So what do I need to buy to do this??

I was going to get something like this for that purpose. I just need the spare money (college bill and car that has a trans problem are very costly). It has good reviews and will work on almost anything, just remember that the item being measured can't be too shiny except for one spot, otherwise it will give a false reading.

Do NOT use your fingers! It don't work very well..:biggrin2.gif:



But seriously, any kind of small digital tach should work. if you have a hobby shop in your area, try and see if they have one , norm about $20 (US)..

i agree jay its hard to count that fast LMAO1:

What about something like this?? I agree, too damn hard to count with fingers! :biggrin2.gif:

These things look like a good tool . Dose any one have one already? How well do they work? worth getting one?:bigthink:

I have an old dwell meter that I used to use on my cars back when I didn't need a computer to work on them. Have not tried it on a single cylinder Kohler but does anyone know if it would work? There is a tachometer reading on it.

In the same boat Weaverama. I have a Craftsman Engine Analyzer like this http://cgi.ebay.com/ebaymotors/ws/eB...5015&viewitem= that I used for tune ups. It only has settings for 4-6-8 cylinder engines, and I haven't looked closely enough to see how or if it will work on single/2 cylinder engines. I use a Sendec tach/hour meter on my 982.

I'll have to see if this works or not but I just ordered one of these Tach & Hr Meter

Got looking today on line....found this one. Anyone have any thoughts on it or is it TOO Cheap - possibly not accurate?

or do I use one like this. Nothing saying I have to mount it, just attach it and test the unit?

I have the one Powerpooch was looking at http://www.amazon.com/Digital-Photo-...4626995&sr=1-3

It works pretty good. I also compared it with a mechanical tach I have and one I have in the dash. All three read within 10 rpm's of each other.

I have one of those and it seems to work okay.

Our shop uses a tach much like the 1st one pictured. They have to mount a small metal reflective strip on a rotating shaft to get the rpms.
I purchased one of these. Have to double the RPMs, but the price was right.

I have a craftsman tach/dwell/voltmeter. One lead goes to ground the other to the positive side of the coil (I think, whichever side works). Since it's a one cylinder you have to divide watch the 8 cyl. scale and divide by 8.
