When the '-arburetor has two different adjustments adjust-ments for the different speed ranges, the obvious thins to do is to trv ad-J'tmeiit ad-J'tmeiit of the uppr range. In mak-adj'j?tnient3 mak-adj'j?tnient3 of the carburetor, the rfcdle should be moved just a fraction ot an inch either wav and the engine tried after ea.-h clianep. AH adjustments adjust-ments should be made while the engine ?5 hot. Misfiring paused bv ignition faults fairly ea-v to lo ate. because it usually in the same cylinder. To test a suspeeted cylinder for ignition mis-i'-r:ng, the spark plug is short circuited circuit-ed with a F'Twiriver or Finiilar in-T7umer.t. in-T7umer.t. Vh.-n the plug is shorted, with no difference being noticed in the operation of the engine, that cvlinder i1- tne g-jiUv one. It mav be that further fur-ther inspection will show the spark Z at fault: it mav be carbonized, rue points mav be too far apart or n-ay be burned, tlic insulation mav be 'racked. At anv rate, replacement of tne pkg 18 the remr-dv. jf tlie dug is foundi very oily at the bottom, this ":av oe rauing the mi-firing. The 01. mav have worke.l its wav past Uulty piston rings or there mav'sinioly too much oil in the crank.-ase. Locating Difficulties. . the spark plug is found to be all ' r;gnt. the wire should be tra.-d riht 1 bi-rk to the distributor and all insula-! t:on breaks should be repaired on the ! ay. Should the wire bo whole, the j trouble may he in the distributor; the i,trributor arm mar not be making' Proper contact with t he segment or ! tf r negment may be dirty.

If the )ut-I )ut-I tery terminals are loo-e or corro.ied the flow of current ma".' be so rest rifted trat missing will occur, and the engine en-gine may even stop flat. The valve sv-terr. i- frequently the seat of misfiring troubles. A sticking iniet valve wiii cau.-e backfiring and if the exhaust valve stick", the cvlin-rVi cvlin-rVi will not fire at all. the charge e--eaping by that outlet. Imprnperiv timed valves will let the fud leak awav and if the springy are weal; the valves will tiot clos? properly, with the inevitable r.vult. Finally, do not be too sure that your particular case of missing is not caused simply by incorrect use of the spark lever. Too early or too late a spark will caue misfiring of an exaggerated order. In some cars control of the advance ad-vance ia through a wire control, the tube of which may be out of adjustment adjust-ment and move with the wire, so that the lever indicates advance, when in reality the control is fully retarded. |
