Jacob’s ignition testing. Thanks to Newbomb Turk….

In the video, I assume the Allen's tach is in distributor RPM.
So double that for crankshaft speed.

'Larger spark'.
A spark that can initiate with a larger spark plug gap has potential to create a larger flame kernal.
or with a smaller gap, that voltage can be used to initiate a spark when conditions are more difficult.

The next part is to have enough energy to keep that spark going while the kernal develops. That can be useful with less than ideal fuel/air and combustion conditions, or if one is trying t ogrow a larger than normal size kernal.

Is there an advantage? Depends but potentially yes especially when conditions aren't ideal.

There are two ranges on that meter. A high and low RPM. Both of those are scaled with engine and crank RPM. It is a bit hard to read.

I really need to make a video showing what the Allen 22-250 can really do.

It will spin a distributor to 12k. Most machines only go to 8k and some less than that. That’s crank RPM.

It can also do a magneto, it can test a module by itself and a coil too.

You can run a magnetic trigger distributor (that won’t run by itself) on the machine without a box.

I really need to do that. I know Tuner wants me to leave it to him in my will.

As for the Jacob’s stuff…I was pleasantly impressed with it.

It looks a bit clunky but it works. And it’s so simple even I can wire it up.

I will start watching swap meets and stuff and I’ll start buying those when I find them.

A big THANKS goes to RF360 for sending it all the way up here and letting me test it. I am glad for the opportunity.
