Hi,
Curious about revs so bought one of the cheap induction tachometers mentioned above from Amazon. Just measured the revs as follows (figures in brackets were not achieved - extrapolated instead - as were some intermediate speeds.):
Look reasonable? This standard 3-bearing Ruby engine also seemed happiest up to about 3000rpm.
