OK is the math you had in mind? It looks like I should have quoted an earlier post. Post 30 "The differance between 50:1 and 32:1 is much less than a 30 degree swing in temperature."There is very little differance fuel to air ratio wise going from 50:1 to 32:1. Do the math and figure it out for yourself.
So when guys talk about their saw blowing up from an oil ratio change I call BS.
And this is another reason Autotune and Mtronic are of benefit to most guys.
But, we are sold a temperature compensated gallon of gasoline. The fuel will be more compact at lower temp, even the bore of the jet itself will be smaller at lower temperature, how about the viscosity of the mix of fuel and oil, even the viscosity of the air. Is there any possibility any flow is turbulent vs laminar that would put one in multiple semesters of calculus.
