My 1974 500cid eldo has trouble cranking for the 1st revolution or so when warmed up and restarted. Starts fine when cold, and starts fine after the 1st crank when warm. It has a rebuilt starter and a very good battery, yet it seems like it can't overcome the engine compression on that 1st crank of the starter. Any suggestions as to the cause? Thanks, Larry

Sounds like the rebuilt starter may have problems with too much current draw. This often manifests itself when hot.

Engine compression was only 8:0.1 on that engine, either you have excess draw from advanced timing or bad battery connections/grounds or a poor quality starter. Voltage drops on the cables and grounds should be done, if all else checks good, do a starter amp draw /voltage drop test. Just expanding on DF Bonnett"s info here.

Just to add what's been offered, the flyweights under the rotor button inside the distributor cap may be sticking slung out, holding the centrifugal ignition timing in an advanced position as mentioned. A drop of oil on the flyweight pins should help although sometimes the inner shaft may get stuck with oil varnish or sludge, making distributor disassembly and cleaning necessary.
