Block number 15F-N-H 25098. Includes pan, crank, cam, pistons & rods, flywheel, oil canister
and adaptor,. Seem to be original bores. Rusty but should be rebuildable. No cracks
or other defects I can see.

Original air filter, also rusty.

$75 for all, pick up in Santa Rosa, CA 95403, Or swap for Spridget parts?
