Oh
This one appears to be OK, just connecting it up and giving it a bit of throttle on the stand it goes from 1K to 3 or 4K RPM like I'd expect, and goes from 1K to 1.5 and 2K on the Choke lever.
The other set of electrics I have really is bad, just constantly showing 5K RPM and should go in the bin.
I could always stick a spare speedo and Idiot light set in it and hang it on the wall.
Perhaps some Hipster would buy it for his 'Studio'.
