Got some new NGK plugs and need the gap for them. What do you think of NGK? If another is recomended, do you know plug maker, number and gap?
Thanks much!!!

I won't use anything else but NKG. I have never had one fail. The correct gap for those engines is usually part of the spark plug number, eg BP8HS-15. The '-15' means a gap of 1.5mm (60 thou to us oldies).

Thanks Much Chris! Thanks for the re-enforcement that NGK are good. The factory plugs were in it when I got the motor used, and they were NGK.
