question about driving a car too lean.?
I recently had my 73 on the Dyno Duster (this is a rebuilt engine might add). Also I had the air / fuel ratio from a wide band on the strip. Unfortunately, the primary carb jets are running very lean. Figure only goes as high as 18:1, but from the looks of the base of the curve, the car is running at about 20:1, in normal driving conditions. And when the jets high school to boot, the car runs at about 14.5. So that's close enough to perfect for me. I have been driving the car this way for several months as a daily driver or even have noticed that running lean, and recently did a compression test and leakage test, and all that is holding very well. So from my point of view, the car must be safe to drive, so that for the new jets. But only for some answers, is a car even though manageable is real lean, while under light load? Or there are still threats to the engine?
winter driving should be well on cargo short distances slight, but in the hot summer day a car that runs real lean could overheat (the thinnest that runs the hotter it runs. but if you do that support you should be fine until you get your jets.
