Rebuild the carb.
Sounds lean to me too.
I would pull and clean plugs for a baseline, then get to adjusting the carb(s). Sounds like a classic case of lean.
At the carb(s), screw the mixture screw all the way in to seated counting turns carefully as you go. Back out to the recommendation (Usually 1 round or a round and a half) and fire it up. Better to be a quarter to a half turn out to the rich than to be on the lean side.
If it doesn't smooth out, inspect fuel lines and fuel filter (Strainer). Follow up with a serving of Seafoam. Best wishes!

Rebuild the carb.
Keep us posted on what you figure out.
Probably be the weekend when I get into it unless I get off early one day, thanks for all the input everyone.

I can be pretty dumb sometimes. I’ve been noticing this cough for a couple of weeks or so and thought I had to remove stuff in front of the carb to get to the adjust screws. So I got off a little early today, got a water tank set up, removed the cover and cranked it up. Knowing it had to warm up some, I raised the idle some and started looking things over as I started to loosen the breather screws. Wondering how much had to come off I looked at the front of the motor. Staring me in the face is the slow speed adjustment knob. I turned it a quarter turn to the rich and it never stuttered once in the 10 minutes or so it ran before impending rain ran me inside. Thanks for all the input, I’ll try to do better next time.
