2n Starting Problem

Besides wornout ignition points, the most likely cause of weak sparkies is..... yer weaksister IGNITION SWITCH, replace it too. ($12, cheap) ..... ..Dell, yer self-appointed sparkie-meister

Yes, most NAPA ignition switches are stronger than the OEM 2-wire weaksister ignition switch with built-in wires ...but... you haffta make yer own wires to use enny NAPA keyed ignition switch and know which 2-posts to use outta 3-or-4-or-more. For most shadetree mechanics, this is a trivial exercise in good electricity practices.

Me? I replaced my OEM ignition switch 3-times in one summer of brushhoggin' before I gotts gripe'd and bought a marine grade waterproof 25-amp toggle switch and wired it myself. Keys? who needs'em eh?..... ...Dell the capable electrician

Some carburetors have a spring-loaded vacuum-relief 'trap-door' as a part of the choke butterfly valve assembly which, if stuck open or missing the spring pressure, might defeat the choke's operation and cause hard starting of a cold engine.

I"ve done the same test lo these thirty years or more by holding the spark wire approx. 1/4 inch from block, but this method is impracticable if the wires have boots; and the 3/16" plug method gives much more consistent readings and is easily repeatable, so I"ve adopted it myself.

If you fail the spark test, and are having trouble finding the bad part, don"t forget the ignition switch. They are apparently very problematic and many on this board were ready to start rending their garments until Dell convinced them to TRY substituting a new switch, at which point the spark became noticeably better.
