Well Scott, making the spark jump from the wire to the plug makes the spark a little hotter inside the cylinder and don't make it faster. There are about 3 different plugs atleast that will fit into the F-20. The only difference is one plug is hotter than the the next and the next is a little hotter. I used to know what number of champion plugs these were but I know the W-18 is one of them. The gap that noname gave of .025" I would say is right. Don't have the manual to look it up in but that is what I set my plugs at in my F-20 and I get along fine. See if all your plugs are the same and set the gap at .025" in all of them and try to remember which plugs weren't firing and put them in the other 2 cylinders when you put them back in. Fire the F-20 up and if the problem moves over to the other cylinders than you need to replace the plugs. If the F-20 still has the same problem on the same 2 cylinders than you have got a different problem than the plugs. Keep us posted on your progress with problem.
