That may be more dependent on how the fuel system is set up and whether you have gravity feed or a fuel pump. I fly in 95+ temps with the KR all summer long and have not had any problems with the auto fuel which is the only diet the KR gets. I have a fuel pump with pressure regulator set to 4 1/2 pounds and I have a cooling shroud on the gascolator with a fresh air blast tube. While I have had the KR up to 11,000 feet, I don't normally fly above 4500 feet so as always, your results may vary. Larry Flesner
