REASON THE CAUSE.

In dealing with engine troubles one should always try to figure out the possible cause of a trouble before starting to adjust something that does not need adjusting. An adjustment should never be changed-without a knowledge of why the change is made, the effect it should have, and how to restore the mechanism to its original adjustment. When the possible cause of the trouble cannot be imagined, then begin with a careful examination of all the features of the engine that are apt to give rise to trouble. If nothing out of order is found, then begin by testing out the varied features, beginning with the easiest and most accessible, and thoroughly complete each test before starting on another possible cause. For example, if your ignition system is suspected, the easiest thing to test would be the spark plugs. First find the faulty plug, then proceed from the spark plugs to the wiring connecting the plug and ignition distributor; then examine the battery connections, the switch connections and, last of all, the adjustments of either the coil or the magneto. Do not examine a spark plug and .then leave it and try a few carburettor adjustments and later come back for another spell of tinkering with the ignition, etc. If you suspect the ignition system, go through it from the beginning to the end in a systematic manner before proceeding with the carburettor. And when you have started on the carburation system, stay with it until you have made sure of the operation of every feature of it between the engine cylinder and the fuel supply.
