Loss of power and missing -8n no timing marks

Thanks

Yes, there is an external timing sliding adjust screw that was important in the days of 1940's 70-octaine gasoline, but with todays modern-87 octaine gasoline in yer 6.0:1 compression flathead engine, it is of NO importance.

You complain..... ."Extreme loss of power and missing"..... .well there is a lotta causes for that and the least of which is ignition timing.

You can't really check your ignition coil with common electronic test meters. But you can test the sparkies quality with enny old sparkie by gently bending the side electrode for a BIG 3/16" gap. Clamp the metal shell to a convient grounding brackett that you can see and connect enny sparkie wire to top of calibrated sparkie tester. Now turn yer ignition switch on and crank yer engine (good engines may start with just 3-sparkies) and WATCH yer calibrated sparkie tester. Do the sparkies jump the gap with "blue-snott" authority? or are they a wimpy yellowish-orangish excuse. ...or... NO SPARKIES at all?

It wouldn't surprize me that yer weak-sister ignition switch has gunked-up internal contacts that cause weak sparkies and missing. You doubt? BY-PASS yer ignition switch with a test-lead with alligator clippies. Or byte the bullett and replace yer ignition switch. $10 (cheap)..... ...respectfully, Dell, yer self-appointed sparkie-meister

Following the procedure, and setting your timing is a good thing to do, however, I doubt it will help any with the problem you are having.
