    I am going though the distributor on my 1935 845. I read on one of the posts here. It said that there is a way of modifying the advance curve, to get a better running engine. What exactly is done, to get this ?


    There are small springs that control the two centrifugal flyweights under the plate that holds the points. Substituting weaker springs will provide more advance with rpm. If everything else is up to snuff the difference shouldn’t be too noticeable, a very slight increase in power and wouldn’t correct a miss, unless one of the springs is broken or missing.
