The original 251 that is in many early SW48 and J5 and even Muskegs is an Industrial motor. The auto parts guys need to look in a tractor book.
My distributor is # IAY 4004-1 which is correct for the Industrial motor. The number is on a plate on the top side of the distributor below the coil. Other distributors were on this motor in other applications and some of the ignition parts will fit the other distributors.
The cap was listed as unavailable. So we found a similar dist. ( IAD 4040-1 ) and used that cap # since it took the same rotor, points, and coil but the condenser # was AL 869.
Most of these are Echlin #s
Cap AL63
Rotor AL62
Points CS725A ( gap about .019? )
Coil IC 14 ( has resistor in it ) IC 12 has no resistor.
Condenser AL 868
Spark Plugs AC Delco R45 ( gap .35 ? )
I'm posting this because a member asked me for the part #s. I didn't buy all the stuff and try it. If you find new info, please add it.
