You should be able to pick up an inductive tachometer fairly cheap online somewhere. You hook the lead over the #1 cylinder and it gives you the RPM.
Do you mean somethin like this? http://www.ebay.com/itm/inductive-tach- … 43a97d0aaa

If you like ebay, go to automotive tools and type in “tachometer” should be able to get something fairly cheap. They link you posted looks like a small gauge to install in your car.
eRIc, do you have a good suggestion? 🙂 it has to have a rpm counter but also something to measure the degrees, relative from for example the TDC
I actually have a multimeter (I got it 20 years ago) that does RPM as well as Dwell, I’m sure you would be able to find something like that to help you out. Ignition timing does not require an RPM reading and if what your working on is old enough to have a carburetor I actually just use a vacuum gauge to set the mixture screws.
Well, as a newbie, we are intending (specially in the beginning) to do everything as described as in the books. So thats why I HAVE TO GET THAT AND THAT AND THIS, but I think if you say that it also would work just by looking to the srews, it makes sense. Thanks for the tip!
Maybe you could make a video about idling adjustment? With the question: why does my engine does sometimes want to stop to run smoothly? (Or something like this…) Just a suggestion, another one like you get a hondred thousand a day 🙂 )

One can find a digital contact or photo (non conact) tachometer from 20 to 100 bucks, depending on where you shop. Here is a link for a $24 dollar one from Sears

A timing light that does RPM is a better option but they are pricey and you already have a working light.
Another option is to put an after market tach under the hood as opposed to on your dash where you can’t see it anyway while making adjustments. Aftermarket gauges are cheap and any auto parts house carries them. The pick up wire goes to the coil and counts current pulses.
You could always pick up a Vibratach from a mower shop.
A vibratach is a wire that is wound up and you let a little out by setting the dial. You know you’re at the right speed when the wire vibrates in a figure 8.
Actually I would love to do an entire series on carburetors when I get the time as I think it’s a dying art. I don’t see to many these days however as you might imagin but I’ll be on the look out.
As for your idle issue, most times idle problems are mixture problems caused by too much air (like a vacuum leak) or a fuel delivery issue, the trick is to find the source.
