hi
my m reg 900c cinq is a brilliant starter from cold, i leave 3 days a week at a hire car yard and have no problems starting when i get back, but over the last few weeks it has developed a problem when it is warmed up, once stopped ie at gargare fro fuel or shops, if it has not had 2 hours to cool down fully it struggles to start, turning excellent but not catching, i have to to pump the accelerator and eventually hold it down and it raws into life, other than that everything is fine it runs well. can anyone offer any advice.

You need to start with some investigation.

When it fails to start, whip a plug out and smell it.

If it smells of fuel, then its more likely to be an ignition problem, if its dry it could be a fuel problem.

Cheers
