Spray alittle wd-40 around manifold to head area around gasket to see if she may have a vacum leak not allowing her to get enough fuel to fire under idle, but maybe enough vacum under load to suck more fuel. just a thought.

Do you know which cylinder fires first...???
The "Trailing cylinder" will very often miss when only under a light load..
That same cylinder (Right) misses as much as it Hits, when idling..
It is not uncommon to need to change plugs, if the tractor idles a good deal of the time..
I do prefer Autolite #3116 in my '52 "B", 520 and 630's ..

Try some Auto-lite 3077s. They are hot plugs that may help your miss fire.Ron Mn.
