Got a reply in the IH area but I would like a little more eyes looking. On a international cub from 1977 what plugs are best. I remember seeing about two or three months ago a whole boat load of opinions. The older books say 8C or D-16. It had RD-15Y plugs in her. I also think that some nut put car wires on it cause I have never seen orange to the side plug wires on a tractor. I will check if carbon when the rain stops. I know Champions have had many headaches and use autolites in my truck. When I pulled the RD-15Y plugs they just had the normal gray deposits with the #3 plug had just a little soot on it. Poured a little ATF in all four cylinders last night. This morning I just gave a little tug on the fan and SHE TURNS!!!!! Yaaa she isn't stuck after sitting in a storage shed for 5 years. Gas stinks to hi Heavens but I am working on that. Only big problem is the left brake. The cross shaft is VERY stiff. I put oil on it and started doing the wiggle thing and just hope I don't need to pull the cross shaft!. What do you folks think? Thanks Jeffcat
