Thanks to the many folks that have given advice. A summary of the suggestions: 1. Make certain the ground connection is to clean metal giving a good ground. 2. Have the rebuilder use heavier winding materials. 3. Ground the battery to the starter (with clean, unpainted connection). 4. Cool the starter with water to see if a reduced temperature makes the problem lessen to confirm the starter problem. After all these, I contacted Jeff Carter who has bailed me out of many difficult issues with the 300F build. He indicated, in agreement with all the above, that it is likely a starter problem that may be due to multiple starter rebuilds (or just age) where the field windings have deteriorated to the point that they have too much resistance and are not funcioning properly and when the starter gets hot, it does not provide the electrical boost needed. That, and the probability that the windings of the armature are not the heavier-duty variety. He no longer knows of a shop that has the knowledge or the parts to do a proper rebuild with new field windings and armature rewinding. Do any of our members have a starter shop that has this experience and parts to do a complete and proper rebuild? It seems that may be the best solution to the problem at hand. I imagine other folks are having, or will have, a similar need. Louie Barrie indicated that he had a fellow with a great deal of knowledge about these things. Any leads would be greatly appreciated.
