question... if the reasoning behind a cloud test is to get the fuel to be on a moleculor level or check to see if its mixed at the moleculor level. than you would also be checking different types of fuel & pre mix ratios, correct?

So, if you are worried about the oil settling on a premix of 24:1 to 32:1 with good premium race fuel shouldnt that effect your given compression ratio at a certain elevation also?

Or would you first determine the type of riding & elevation. Figure compression ratio, than perform the "jar" test to decide what fuel and at what premix to run..

or is all this just for running avgas and premium fuel mixed. i remember someone saying if the race fuel is mixed on the moleculor level than a % of pump gas should be added.
