My 37 is hard starting when warm--it barely turns over or does not turn over at all until cooler. The car runs fine while driving. The restorer put a new battery in, new starter, new battery cables, and new starter solenoid. You can hear the solenoid click, but no luck with the starter. the car does not run hot at all. Also they had the engine out to replace the clutch and clutch plate and no notice of a defect on the motor was visible then. Thoughts??

Is this a fresh restoration? Is it still a 6 volt positive ground system? What gauge are the new battery cables? Are the cable connections at the battery clean and tight? Are all ground connections free from paint and are they clean and tight? There should be no paint where the starter motor mounts to the block - this is the ground connection for the starter motor. The engine block should be on the ground side of the battery. The engine block, frame and body should all be electrically tied together to ground. You can't have too many grounds....

Read this post and do the test that I posted. It is important to do tests like I posted so you don't waste money on parts that you do not need or add new problems by installing bad parts. https://www.earlyfordv8.org/forum/viewmessages.cfm?Forum=18&Topic=14050&keywords=slow%20starter If you don't find the problem doing those tests, post the results and we can give you more help.

After taking your 37 for a drive and returning back to the garage .... while still hot, remove all spark plugs (which now there is no resistance in the cyl's) and see if the engine will crank. It could be a beginning of the process of elimination. If there's still no cranking, starter isn't sending out sufficient juice.

Hard starting when hot is a common problem. The heat under the hood after a long run affects the ignition coil resistance, lowering the voltage. The starter also is heated by the nearby exhaust manifold, and draws extra power, for the same reason, also starving the ignition. Years ago, I posted a page showing a "quick start" circuit which is easy to make at low cost. It was widely circulated, and I can look it up. or anyone who has it will save me the trouble.
