Slow cranking..?

[max_s2]

Hey everyone.
A while ago I noticed that my ABY coupe cranks a bit slowlier when engine is hot than when it's cold. If I leave her cool down for a hour or so - she cranks up again normaly. Is this ok or should I check for something?

clearances will be a bit tighter when its hot, not sure what difference that would make?

I would think its something to do with the electrics, maybe something simple like a bad earth or a cell breaking down on the battery

All the cars I ever had crank faster when hot as the oil is thin and friction is less,
I agree with the above that it may well be electrical or your starter motor is suffering from
heat stoke as it is fooked.

When starter motors are getting old, heat will slow them down. Same with the cables...

Problem with lots of race cars ...of the starter cable is hot they don't supply enough juice to start

I did the same thing especially before done the gearbox conversion.once I had the loosen + terminal on the starter,cranking was way much more slower when hot.I cleaned up the oxide and some burnt on the terminal ,re-tighten it.the cranking sound is sound healthy again.
