[QUOTE="dieselfixer, post: 334428, member: 4887"] My brand new 9.9 Mercury 4 stroke was doing the same as your engine, I got rid of regular 10% ethanol gas and am now using 91 octaine no ethanol gas. The engine now starts on 1 maybe 2 pulls when cold and 1 pull every time when it is warmed up it has more power and runs a lot better. [/QUOTE]
