[Farmall] "H" running a little rough

[Mike Sloane]

Like all (non-electronic) ignition systems, the usual suspect is 
moisture that condenses inside the distributor, and outside on the 
Bakelite cap. What happens is that the moisture provides an electrical 
path either to ground or between the towers. Those old ignition systems 
just don't have enough power to overcome the leakage paths. Very often, 
cleaning the inside and outside of the cap thoroughly with a clean dry 
rag (or spraying with "moisture repellent") will solve the problem.
