Hot starting problems

[active1064]

Over the last couple of weeks my 350i has developed a hot starting problem, you have to crank it over for ages to get it to restart. From cold it starts no problem.
It has a rising rate fuel regulator and was hunting at idle when warm, so I adjusting the idle speed using the bleed screw ,which stopped it hunting, but now it has starting problems when warm. Any help/advice would be much appreciated.

Cheers

Cheers for the help, it does seem to be connected to me adjusting the bleed screw.The car starts a lot better if you use full throttle, not ideal as it wakes up half the town let alone my street.Is there any tips/tricks to know when adjusting it.

Many thanks in advance.

Hi Ziga

Yes, mine is 350i with a 3.9 engine. Hunting really badly so set the idle to around a 1000, stopped the problem but now doesn't like starting when hot.
