Hi, does anyone know where I can get some ? A 1-1,5mm copper disc may work as well, I guess. My problem is that the valves are so big that one electrode shows slight wear on the outer side. Spark plugs like Brisk or Golden Lodge with a different electrode design may be a solution, too. Will have to look into that also. G. |

I think you could use indexing washers. Here they can be had through catalog speed shops like jeg's and summit from companies such as morosso and accel http://www.summitracing.com/parts/ALM-1002M/ Even an automotive speed shop or performance auto parts store might carry them. |

now where the hell do they sell go cart parts here in Germany ?   But I`ll check scooter parts shops. There`re many scooter tuning shops here.Thanks for the pointers. I`ve seen that also NGK sells different sets but why buy a 30 piece set for over €20 when I only need two  G. |

you need the whole set because everytime you change your plugs, you need to put the correct shim in for that plug. I have not used them, but the concept is that you want to position the electrode arm in a specific orientation relative to the head for optimal ignition and flame front travel. The start thread of a spark plug is not oriented to the electrode arm. At least, thats my understanding of spark plug spacers. Cheers, |

also with the head on it is a matter of trial and error to determine which shim to position the plug in the proper direction. Some engines run best with the electrode gap pointed at the intake, some away from the intake still others somewhere in between. This is one instance where a dyno is the best way to figure out the proper orientation |
