Will not start, need some advice.

Went out to barn Saturday to get lawn tractor going and though I should also start up the 1953 NAA. She started fine, but when I turned on the lights, the engine cut right off. Now will not start at all. Engine turns over, but will not catch. Advice on what to check, please.

Thanks in advance.

The weaksister ignition switch internal contacts gitt gunked up over time and when you turned yer headlites on this time you OVERLOADED yer ignition switch and lost yer sparkies.

Now you have 2-problems, NO sparkies (bad switch, $15, cheap) and FLOODED sparkies from crankin'. Do I haffta tell you to replace yer BAD weaksister ignition switch???

REPLACE yer FLOODED sparkies with new DRY clean AutoLite 437's gapp = 0.025". Don't throw yer flooded sparkies away, dry them one-atta-time in HOT running engine and sav'em for the NEXT time you have starting problems..... ..Dell, yer self-appointed sparkie-meister

Those ignition switches were made for the 3-4 amps of current to power the primary sid eof the ignition coil.. not the 6a per lamp plus the ignition ( 15-16a ).

I like to power my lamps from the same post that feeds power tot he ignition switch ( this is the charge/load side of the ammeter basically )

start there.. use a vom or a test lamp and chase the votls.. see where you have them.. and where you loose them.

as a test.. jumper from battery hot to input/primary side of ignition coil and try to start her.. if she starts.. you know the problem is in the primary circuit between the battery and the coil.
