I always liked that meter. It worked great for my 83 CJ7 until I changed to a new fuel injected engine. I'm not writing it off yet.B RON CO":3db47oc0 said:Hi, the Heathkit meters are very good. Verify it on another car if you can.
The lowest plug in the picture can be rich or probably oil fouled.
Good luck

Unless you were using a tach / dewell meter as in a professional setting (full time mechanic or tune up shop) it's unlikely it could ever go bad, other then dropping it or other destructive forces. In any case checking it against another meter will tell the tale. Good luck edited

These were taken a couple days ago before I realized the carb linkage was hanging up. Probably more like 1000 rpm.

The links are working. Yeah it sounds like 1000+ to me. It sounds pretty smooth, sounds like the ignition system is working pretty well, no big misses. Not a horrible place to start. I'd like to see a video of it idling around 650, or as low as it idles nice, and you putting it into gear w/ your foot on the brake and holding it still. After you get the timing and the dwell set.
If you have the throttle plates all the way closed on the outer carbs at idle, w/their mixture screws turned all the way in and with a smooth idle, can you then kill the engine by turning the mixture screw in on the center carb? Doing that's making sure there aren't any vacuum leaks and the idle circuit is working right on that carb. If you can pass that you should be able to tune it up real nice.

Had a little time to play around today.
Got a video of it showing the tach at 600 and the dwell setting - about 27.
Got another video of it at 800 and then the dwell - about 34.
Not sure why there's that big of a difference, but I haven't measure the points yet.
I have both outer carbs disconnected and confirmed that I can get it to stall by turning the mixture screws in. Right now all three are 1.5 turns out.
Took if for a short drive - surges with the throttle. Doesn't have much get up and go yet.
videos are rpm first, followed by dwell.
