I have been searching ebay and all the(analoge) dwell meters look close to the same so can anyone recommend a certain brand or type? I was able to set my mixture level last night using the "ballpark" method and it did make a world of difference, but now I'm wanting perfection. Does it make a difference in brand or is it such a cut and dry procedure that any dwell meter will work?

MHO - get a digital one that also has a duty cycle setting, as then you can adjust not only by dwell, but also by duty cycle.

I'm personally very happy with the meter I purchased - Sunpro by Actron Cp7678.

I have a NOS version of the meter (with the duty cycle, dwell, and rpm settings to the left of off), which is made in either South Korea or Taiwan (depending upon the case - the South Korean ones have the auto off and water resistant label at the top, while the Taiwan ones have those labels on the bottom), like this:

The newest versions of this meter are Actron branded only (no Sunpro and have they duty cycle, dwell and rpm settings to the right of off), and I'm not exactly sure where they're made:

I've always felt that the wider the needle sweep the more accurate I could get it. I have an older Radio Shack multi-meter that has about a 3'' 90 degree sweeping needle. Easy to see and a responsive action. NJ emissions test have always been well within specs with air fuel ratio at about 14.3. So, the meter seems to get me set correctly. And, the engine runs well.

This is the one that I (and I believe a few others on here) have:

Has worked pretty well for me, and only about $30 on Amazon.

That's the one I have. Works great.

I will get that one for later use. In the meantime I borrowed a friends that has a duty cycle on it. Maybe harder to read but it will get me close.27580

I personally don't think you can beat this one http://www.amazon.com/Actron-CP7605-Tachometer-Voltmeter-Analyzer/dp/B00062YUUS/ref=sr_1_1?ie=UTF8&qid=1401562803&sr=8-1&keywords=dwell+meter for our cars. The digital meters are very "sterile" and since they only show the current reading as it is sampled, you don't get a real visual on the trend. Setting the dwell for K-Jet involves monitoring the sweep of a needle, something which is very difficult to do with a digital readout. So while the point in time measurement may not be as accurate on an analog meter, it's still a better tool for the job. My $0.02, I love my Actron meter.

Edit: Same one others recommended above, I hadn't clicked the link until after I posted. So the tl;dr on this post is "+1 Actron"
