Less fuel on start will allow them to start easily. I worked for one operator where the owner didn't even know how little fuel they needed on start, he'd sit there be priming it for well over 5 seconds and flood it 99% of the time. Engine driven fuel pumps on the 540s are rubbish, there's plenty of reports on them failing and I've personally had them fail on numerous occasions, make sure you know your emergency procedures in relation to boost pumps. It will save your life.
