With distributor there are several things to check.
1-Is the terminal connection on the point plate at the points properly insulated. Sometimes this small insulator gets damaged.
2-Are your mechanical advance (Governor) weights free to travel and spring back properly? A quick check you rotate the distributor rotor against normal travel (advanced) and it should move freely 10 Degrees or so and when you release the rotor it should snap back to it's original position quickly.
3-Have you checked your condenser and the radio noise filter capacitor with a proper capacitor/condenser tester or at least substituted know good ones. These can often have their resistances varied too much by heat.\
4-Have you checked the primary & secondary resistance (in OHMs) of your coil both cold & hot? By hot I mean uncomfortable to touch hot. You can heat the coil with a hair dryer. If there is a significant difference in readings Hot vs Cold then substitute a known good coil.
Slow starters are caused by:
1-Poor or missing grounds. The ground strap should be installed at the right front engine mount. The contact area of the face of the starter and the seat area on the bell housing should be paint free. Bolts should be clean and contact areas on both the bell and the starter paintless. The battery terminals must be clean, corrosion free and tight. Again check for clean paint free contact surfaces.
4-Damages or overheated armature/commutator.
Be sure to use the extracts of TM 9-1825B dated 1952 for troubleshooting these items. The applicable chapters are available in PDF on our downloads page. _________________ Wes K
