[QUOTE="greg brillus, post: 98739, member: 597"] The wires that come out of the mag and connect to the coils are set up in pairs, two brown and two blue ones. You only need to find the coil where the wires are in pairs and either blank the second wires that goes to the other coil, or simply cut them off, and remove the second coil (keep it as a spare) Then you just set up the ignition timing as per a single plug ignition. It will run fine, the twin plug set up is only beneficial to an all out racer using very high compression pistons where the tall dome masks the flame travelling from one side of the combustion chamber to the other. The 600 Norvin I have just finished runs one of Terry's top end kits with the squish band piston set up, I am using the left plug hole for the plug and in the right one I have one of those Enfield decompressors which works fabulously, it is so easy to use and starts very well, this with a 36 mm Mikuni carb and factory spec Mk 2 cam. All good.............:) [/QUOTE]
