I bought a generator head and engine from someone who planned on
making a generator set for those times when the electrical power is
out. And I plan on finishing the project. However the seller had
misplaced the pulley for the generator. ( it is designed for belt
drive ) And the generator shaft is 24 mm. I can get a pulley and
taper hub from WW Grainger, but thought it might be cheaper to get a
pulley at the auto wrecking yard. Before I take calipers in hand and
wander thru some wrecking yards, I thought I would ask the group if
24mm is a common size for the bore of crankshaft pulleys.

Lovejoy couplings would be cheaper, but I would like to run the engine
at less than 3600 rpm.
