cold fuel
Hi,
Interesting.
However, while its true that cold fuel and, more importantly, cold air is denser and therefore more mass of charge for a given volume gets into the cylinder, thereby producing more power, its surprising just cold fuel made the difference in the revs you mentioned.
I suspect its more likely that the denser fuel made the mixture a little richer, which might explain the extra power, as it might have been a little too lean, which, of course, could have been achieved by richening the mixture in the normal way.
Nevertheless . . . Interesting!
