Strobe timing test

Though I'm not sure because of old story on spare parts thyristor a few years ago, I must have prepared spare one at that time.

However hard I might look it for, I couldn't find it out today.

I tried to make strobe timing light for checking it on EP82 TOYOTA Starlet, distributor of it is adjustable and replaced into EP91's one.

But the DIY timing checker did not work well at that time, more adjusting was necessary.

Later timing checking using strobe timing light, no further adjusting was necessary. My testing way not using electric device but using my own 5 senses with actual road running test made it unnecessary to do.
