356 engine run in stand

[JTR70]

Very slick, I like it!

It lives... Got all the instruments to operate, now for some calibration and I should be done. Has turn signal indicators in the TACH, so they are now tied to the oil pressure light. I used some 8mm LEDs instead of the 2w bulbs. The green lense is bright and will get your attention.

Inspired by John's efforts with the colourtune I got mine out. The car had been running roughly on the idle circuit. I had tried tuning using a rpm counter/ear a couple of time. It was a pain to get the colourtune on/off. Plus I had to use my own mirror to see the flame. However, it said I had it too lean I adjusted out until I saw the yellow flame and then back in again until the blue appeared. Then the engine suddenly came back to life. Running another 400rpm better and smoother. I didn't use the colourtune on the rest but adjusted to max rpm.

Yes the color tune is not easy on a 616/. But I found a cheap fiber optic borescope works well. Out of the car it's not too bad, but in a running car it's an afternoon of neeling
I was also surprised after balance and peak the carbs using the tachometer, to get another 80 rpm with the color tune, with the same unisync setting.

I wish my rpm was good to tell me +/- 80 rpm

I've read that sometimes people made the mixture a little richer than the max rpm?
