Setting the mixture is so easy on these things, if the fuel diaphragm isn't
performing
properly, you may be able to get more life out of the unit until you get the
parts.
Generally if you want your unit running properly (keyword) you're still going
to have
to do it when you get the parts anyway. (shrug)
Adjustment is usually moving the screw 1/8 of a turn until the engine idles
smooth at
either end of the rpm range. (some use just the idle setting.) It is in the
manual. If they
didn't want us messing with it, they would have sealed it, and even then, the
cap can
usually be removed.

Mixture adjustment doesn't go bad all by itself.
I don't suggest twiddling the adjusters. Find the real problem.

Correct about the diaphram. If you have to go into the carb to check for
clogged jets, check that too.

Plugs don't usually foul when the engine is running warm and WFO.
When they do foul, the engine won't start. So that's not it.
