When you say nothing works, what are you comparing with?
You can check the gearing revcounter drive in the head by watching how many engine rotations it takes to make one revolution of the cable.

I have used CB92 race tachometers. The face reads 20:3 so, I suppose that would equally 6.666 :1 but I'm sure others will have something to say. Lol
Thank you for Response
I buy the Smith replica revcounter from Scott Mitchell UK.
4;1 was to slow real 6000 turns show me 2500-3000 turns
2;1 was slower real 6000 turns show me 100-1500 turns
7:1 ( Scott let build him for me ) show nothing
The cabel turns against clockwise. That was correct on my Smith revcounters.
I see also revcounter with Ratio 1:4 1:5 or 1:7 could this be the problem?
Years ago I used a rev-counter off a small Kawasaki two stroke. It was the correct JIS ratio of 20:3 and worked fine. Can't remember the scale reading but it was on my race bike so must have been OK. It also came with an angled cable connection on the back which made mounting it and getting a good cable run much easier. It could have been off a KH250 or 350
