1. engine will not start by normal cranking:
possible cause -remedy
(a)dirty or corroded distributor points. -clean or renew and adjust points
(b)carburettor flooding -check needle valve and float, clean out fuel system
(c)moisture on high tension wire and/or inside distributer cap. -dry out high tension wires and cap
(d)dirt or water in carburettor or fuel system. -clean out carburettor and fuel system
(e)incorrectly set spark plug gaps. -reset spark plug gaps to specification
Verify spark is strong enough to jump in the cylinder. Rare failures will produce a spark when the plug is grounded outside the engine, but won't jump under higher cylinder pressures.
(f)faulty coil or capicitor. -test and renew faulty components.
(g)faulty high or low tension wires. -test and renew faulty wires.
(h)fuel vapor lock. -check source of vapor lock and insulate against heat.
(i)faulty fuel pump. -test and overhaul fuel pump.
(j)incorrectly set ignition timing. -check and retime ignition.
(k)broken or short-cicuited low tension lead to distributer points. -test and renew lead.
