Car dropped 250 RPM and is now stuttering

I'd still check the alt and battery. Takes 2 min

I used a multi meter to check the voltage at the battery. Everything is at spex.
12.8 resting
14.10 running
13.8 with a load

Anything else I should do to test the alternator?

One of my buddies suggested to check the fuel pressure so I slapped on a gauge. 7 psi steady.

I guess it's on to taking off the carb and opening it up looking for blockages.
