[Farmall] gasoline/spark plugs

[CAMEROL78 at aol.com]

I use Champion d18y or autolite 45's and they seem to work well. You might  
want to check your air cleaner or also see if your choke is not partially  
closed. Black plugs are a sign of a rich condition. i've also found if you work  
the engine hard they clean the plugs better. Loafing the engine doesn't build  
enough heat in the cylinder to burn the fuel very well and can cause fouling.  
hope this helps
