Rich or Lean

[440ex2001]

Does your mixture get richer or leaner when its warm out? Today it was 72 and my 440 never ran better. I figure my jetting s off.

Warm equals less air, because warm air expands. That equals a potential rich condition.

Cold are is more dangerous. It is more compressed. That equals a more lean condition.

if you jetted it when it was cold out then it will be running richer now that i is warmer out.
