crate motor in 5O half ton ran fine for several hundred miles. One day while sitting for 1O minutes while in a store, came out and would not start. Seemed as if starter could not turn over. Got a shove, let clutch go and off it took.

Drove home, no trouble, shut down and same deal.

Truck went into storage for a few years without resolution. Now still has same issue. Essentially new starter too weak, or so it seems. Shimmed starter both directions. No change.

Cranks without s ark lugs installed. Gets oil flow right away.

Before I tear into everything, I thought I would ask. I have not changed anything I know of relative to distributor, timing, etc since it ran. It makes no bad mechanical noises.

sos thanx!
