Running on 1 cynlinder

If I replace one spark plug on a twin, I replace both. You did check that the cooling fins were not plugged?

I did replace both spark plugs but one of the spark plugs i bought the procelin was broken and i haven't had the chance to get a new one, The engine is really clean, i've had the cover off it and the fans are almost clean enough to eat off of.

One cylinder running leaner than the other.
Popping at idle could also be from it as well.

There is no carb adjustments so how i would go about, fixing if one is leaner then the other?
