When idling are both carbs (for lack of better knowledge) being used?
If I pull the upper plug it stops running, if I pull the lower it still idles (when upper is plugged in).
I am not a mechanic so no idea.
Another guy said both are needed to idle and it may be electrical problem? *Said maybe the coil? I do not have a trailer and am far from anywhere so am trying to repair at the dock. Thank you.

Every once in a while (several running hours apart) the motor will slow down, speed up, slow down, speed up then cut off when running at full or high throttle? restarts ok after that.
But recently it just stopped while idling in gear.
Easy to restart but would not idle even in neutral. Would run at higher speeds.

I did all the usual fuel related checks: new gas, fittings, checked filter, replaced plugs, primer bulb, seafoam, etc

thanks for looking

p.s. I have another thread I am trying to cancel but when I use edit there is no delete button?
