Re: Evinrude carb gasket with wire mesh opening

Dang. Here I sit, having a senior moment, can’t think of the whyfor. But I have heard motors lean sneeze about a million times. So have most others on this forum. Most of us have also been spit in the face as it blows back through the carburetor. It is the cough, or snort, or sneeze that occurs at idle speeds when the incoming fuel charge has too much air in ratio to the amount of fuel.

Ah, it’s starting to come back now. At the bottom of the stroke, piston uncovers exhaust and intake ports, there is still fire in the cylinder, which ignites the fuel coming in through the intake ports from the crankcase. I think I got that right. Somebody help me out of this if that isn’t right.

EDIT: A correct fuel/air mix doesn’t ignite as it enters the intake ports, because it is not a combustible mixture until compressed. Or something like that.
