Any opinions or advice on this appreciated. When starting cold my starter motor is always flawless. However when up to operating temperature, like after stopping for ga$, it will sometimes make a crunching sound as the engine fires. It sounds to me as if the starter pinion is either failing to disengage for a split second or it is rotating faster than the engine pinion. Also occasionally it will slow down as the engine fires like a Harley will when pushing against engine compression. The starter looks as old as the car and hasn't failed to fire up the stock 360. Should I just replace the starter?

Back the ignition timing off a couple degrees and see if that helps.

Cue the mini starter recommendations... :mob:

Thanks John. I currently have the timing set at 0 backed off 2 1/2 degrees from stock, I believe. When I first bought the car I think it was retarded 4 degrees. At that time the starter was sometimes "lazy" after a rotation but always started. It ran ok on 87 octane with 10% ethanol but pinged once advanced to 0 and now I'm feeding her 91 octane without ethanol which cured the ping.

I agree with replace or rebuild. If you go the mini starter route, @Badvert65 sells conversion kits for the ring terminal mounting studs.

Thanks Ben. Any specific recommendations for a mini starter? Are they better/less expensive than a replacement regular size or rebuild of the original? I don't want to find myself stranded at the ga$ station!
