converted ignition to electronic in stock dist.now using r44 plugs and wondering if i need hotter plug.noticed some fouling on two that i pulled.any help is appreciated jc

 

First, what is fouling the plug?
Carbon build up, running rich.
If it's oily, you may have bigger probs.
How many plugs are fouling, and which ones?
The more carbon, leans me toward rich mix.
Check fuel/air mix.
If no change, after tune up, then yes, go to a hotter plug. IMO!
