Air Maze Air Filter on Zenith Carb Question
’ve used the Air Maze filter for almost 30 years - recently replaced the ‘screen’ filter element for a real paper air filter. The rebuilt engine was installed in March, carb rebuilt a couple of months ago - engine runs very well. I can turn the GAV off and the engine begins to stumble, so I believe at 1/4 turn of the GAV out, the engine is getting a pretty reasonable mix of gas/air.
However, I changed spark plugs a couple days ago - swapped some Motorcraft pugs from Bratton’s (since March) for a set of Champion 3Xs and noticed that the Motorcraft plugs had quite a bit of carbon on them, I wondered if the air filter was making the fuel mix too rich. I;ve read about this, and wonder if I need to do something to the Zenith carb to compensate for the air filter. thoughts ?? thanks - Jim |
