I have previously read all of the MC16 FAQ/Search threads about the cold-solder joints of some CDI componant such as the "Do Not Despair" one and I will excavate into one-unit as a last-resort since its stuck-down in a dark/dank underground parking garage, at the moment.
I have been saving one groovy new 'multi-spark' CDI box spares from CSBK150ccGP[Bucket] that I can substitute as the connector syles are identical, so why not try it for spark, though the advance curve is un-known as yet.
I live in China and I get these semantical lingo-problems on a daily basis: ".... I can switch/swap the INPUT LEADS INto the EXISTING 2X CDIs and THIS ACTION CHANGES THE SOURCE OF TRIGGER PULSE, WHICH transferS the nice purple~blue spark FROM ONE CYLINDER TO THE OTHER....". Now then, the kind reply starts to confuse my early senility with a paradoxical conundrum: "....if you are "swapping" the cdi unit and the spark is following it then I'd say the cdi is goosed...."
Ok, let's see: I am Not "removing" the existing Old CDI Boxes and 'replacing' it with another NOS CDI to Swap-OUT... I am simply 'changing' the input sources [wires] to the same [left-and-right?] CDI Boxes with matching old Ign.Coils for each box, in-situ.
So, IF I "Trade" the Ignitor Input Wires going INTO either one of the CDI boxes [of which the one-wire solo/alone in the double-molex seems to be the respective ignition trigger pulser] and then that one [L-or-R CDI Box] will then make an Ok Spark to its respective ^top^or \bottom/cylinder.
This repeatitive experiment [done-in-the-dark!] indicates to my remaining naive brain-cell that BOTH of the CDI Boxes can make a nice blue-ish Sparks and run either the up-or-down cylinder, for a little bit.
Now, i want to feed 'good' signals to Both of the old CDI Boxes so that maybe the dang thang will actually run on TWO cylinders and i can blast out of the Temple of Gloom into the fresh sunshine and rescue me old 250NotSoRight to hoon-it back to its natural habitat, whew!, safe at the race-track here.
This poor-thing has been 'maintained' by chinese tractor mechanics and I am trying to return it to its natural condition of dottering glorage, but it still remains a crippled poster-child searching for its faithful pet "Sparky", sniff~sniff and so I have to reach-out via the E-beacon, beseeching the winged Super Heros at NSR-World HQ to use their fantastic mental powerz-of-deduction to help save a pitiful forgotten-relic as it crossed-over into the bamboo-boneyard of misty oblivion ... ????
