It was one of those new starters that several parts vendors are selling. I rebuilt the original Ford starter and it turns over like a new one. You just can't beat those original Ford parts. Thanks again for of you that gave me suggestions. Jerry 40 Coupe 07-28-2022 @ 8:05 AM reply profile send p.m. Senior Posts: 1648 Joined: Oct 2009 36 could have the foot start or the push button. If you have the push button on the dash consider checking voltage on both sides of the firewall solenoid when the engine will not turn over. The problem could be the start solenoid main contacts. voced 07-28-2022 @ 4:30 AM reply profile send p.m. Member Posts: 86 Joined: Oct 2009 thanks Tom; I will check the voltages. Currently I am having the original starter rebuilt and I ordered a new Optima 6 volt battery.

Remove the inner caps and see if you can rotate the rotor. If you can have the distributor serviced. Worn or bad points can also cause changes in timing that cause the the engine to buck the starter. Do a search for Voltage Drop , all topics and ALL in the past box. Basically you should not see more than 0.6V drop from the NEG post to the starter when cranking the engine with the ignition off. The POS post to the starter mounting bolt should not exceed 0.1V If the grounded voltage is high, your starter is drawing too much current. You can make these tests on a warm engine and should get results even if the starter cranks normally.

Does your engine have the poured Babbitt bearings or the later type of insert bearings on the crankshaft? Because your slow cranking problem is intermittent, suspect something is changing within the engine from time to time. Is the oil clean and free of contaminants like dirt, metallic particles, anti-freeze and water? Contaminants getting onto the bearing surfaces will increase the friction and slow the cranking speeds. If you have the poured Babbitt bearings, the contaminant particles will get impregnated into these "soft" bearings and allow a reduction of the friction to temporarily restore proper cranking speed.

Good sealing of the valves is required to provide adequate compression to start the engine. Warm the engine up to operating temperature before removing all of the spark plugs (if you have cast iron heads) and do a compression check while the engine is hot. 37RAGTOPMAN 07-26-2022 @ 2:40 PM reply profile send p.m. Senior Posts: 1941 Joined: Oct 2009 SLOW TURNING ENGINE, did you try turning the engine over with a hand crank , cold then hot ???? let us know, thanks 1937 Ragtopman carcrazy 07-26-2022 @ 10:52 AM reply profile send p.m. Senior Posts: 1587 Joined: Oct 2009 What has not been changed? You have changed almost everything that could possibly be causing your starting problem. When you crank the engine with the starter, does the RPM vary like the flywheel ring gear could be out-of-round? If the engine cranks slowly when trying to start and all of the electrical system checks out as being good, the problem could be caused by excess friction somewhere. When you go to start the engine, do you have the clutch pedal depressed so the engine does not have to rotate the transmission input shaft and gears? If the transmission gears are being rotated while you try to start the engine and you are using a high viscosity oil, the engine will turn over more slowly. You might want to use SAE 90 weight gear oil in the transmission. voced 07-26-2022 @ 4:57 AM reply profile send p.m. Member Posts: 86 Joined: Oct 2009 Thanks Carcrazy: It happens even if not hot. It also happened before I rebuilt the motor. It runs like a clock. Sometimes it turns over perfectly and 3 out of 4 times it just grunts like a low battery. It has been frustrating considering that I have added grounds, and replaced every item that could cause this. Thanks again for your ideas. Jerry
