Show Carburetor Not Always to Blame for Bad Motor When tlie motor does not perform perfectly, when it hits on all cylinders only after reaching a certain speed and Jerks badly when the throttle is opened after running slowly on high gear, the owner generally blames the carburetion. He figures that he has a poor mixture due to the fact that after fifty or one hundred yards the motor picks up and hits on all cylinders. Troubles of this kind are mostly due to poor Insulation in tlie spark plugs. Ordinary porcelains are porous and allow al-low so much current to leak that only a weak spark is delivered. After throttling down, the mixture is not perfect and the spark is so weak that it will not ignite gas properly. It is a very common occurrence for automobile automo-bile owners to buy a new carburetor to eliminate trouble of this sort. Tbe first thing an owner should do before going to other expense is to ascertain whether or not his spark plugs are all ri'ht. |
