1936 Ruby with original engine bored out to +60 thou. with LC head.
All wiring replaced and heavy gauge battery connections to starter and earth.
All ignition components replaced
Here’s the issue when standing for more than one day takes for ever to start BUT will eventually start and run fine
Once it’s started initially for the next day or two starts straight away.
Not really a problem because even when standing the previous two weeks same situation
Possibly the car just misses me and is making a protest at not being used
You never know

Have you taken an earth lead from the starter battery directly to a bolt on the gearbox or engine? If your earth is just to the body, the voltage drop can be significant.

Hi
Is fuel leaking very slowly out of the float bowl? It takes quite a while for the pump to fill the bowl.
Cheers

If my car has been standing for more than a day or so, I make sure I use the priming lever to manually fill the float bowl with petrol before operating the starter. Usually results in an instant start.

Yep, if you’ve left it more than a week, prime the pump every time for an instant start.

Thanks for the suggestions
Sorry I forgot to mention I prime the carb every time.
Also the Earth lead goes direct to the starter motor then back to the chassis.
I may try an additional lead from battery to chassis
Then disconnect the starter to earth lead , if you follow me

Clean your points in the distributer / check points gap. (points burn up quickly if the condenser is below par).
Also, is there too much slop on the distributer shaft making the points gap inaccurate.
Possible crack in the distributer cap ? (did you replace with a new one?).

I find that both my '34 Ruby and my '55 Austin Cambridge take a bit of cranking over before they start, when they've not been used for a week. A little squirt of petrol into the air intake of the carb and they start instantly.

My '28 Chummy can also be calcitrant in starting and has been all the years I've had it. Flooding the carb helps but I need to wind it over for around 10-15 secs. The 6v battery is good but magnetos are notorious for their inefficiency at low revs. Occasionally I've resorted to banging 12 volts thro' the system, resulting in instant start up!

Hi
Have you tried putting a voltmeter across the battery? As has been mentioned the volt drop when the starter is in operation can mean that the ignition struggles with a spark. On a weak battery the problem is worse. I’ve found that if my RK doesn’t start quickly with the starter a hand crank will work. It allows all the available power to the ignition.
Cheers
