Your motor was design to run on 87 octane at fuel/oil of 50:1.
If the spark plugs were in good shape prior to the Seafoam decarbing, then they will be fine after the decarbing. Naturally they will be junked up, but just clean/soak the junked up ends in a small tin can of gas. Just stir the tip (in the gas) like you would if you were briskly stirring a mug of hot chocolate. When the junk is off, then rinse the plug with water and lightly sand plugs ends with sand paper to clean them off well. Re-rinse with water and dry the plug very well. Good as new! (come on, they are just spark plugs :LOL2: )
If the plugs have been in for a long time, then get a new set of plugs, they are probably $6 or $7 at most for a pair.
