Oh yes agreed.
Definitely need to clear the Engine of any un-burnt fuel during the next start, possibly consider a manual start to run at max motoring before introducing the fuel?
On the 330, 744 and 777 you always need EGT below 100 c before introducing the fuel anyway. ( well my experience on RR and GE anyway ) this should suffice as the EGT would be quite warm after the first failed attempt and it would motor for a while anyway during the auto start.
