I'm in New Mexico, USA and have the same/similar Walker-jet 200 (Fly version, vs Siminoni version)... but Viktor made the pre-2006 engine (electric start) ignitions using a 4-connector "regulator" (the small aluminium 'box' with the heat sink fins) which is also an AC to DC rectiifier... used to recharge the batteries. It is my understanding that the engine stator that WJ-CZ uses are all 4-wire, but one wire is not used (it IS connected to the Engine's Neutronix twist-lock connector (Plug - male) on the engine outside, but NOT connected on one of the Neutronic socket/recepticle's (female) internal-side terminals (NC). You have the identical symptoms that I have: " weak-spark voltage" and hence... I bought a new stator, having tried a new CDI coil, boot and regulator. I also had switched out the throtle switches, but to do that properly, you apparently must FULLY rewire all 3 switches, in order to maintain a full circuit path (or not short the red/blue primary contacts on the CDI coil... which would account for your original "No-Spark" condition. It is also possible that just making that throttle rewiring, 'might' damage one of the 4 coild on the stator. FYI - the engine's stator should develop approx 250-280 VAC, at full RPMs; which is passed to the CDI coil and then boosted to approx. 10k VAC for the spark. I'm currently re-connecting my ORIGINAL stator, per factory spec and will see if the spark is truely weak, now that I've reconnected the throttle switches back to their ORIGINAL factory configuration. IF that still produces a 'weak-spark', then there is only 2 parts left: the CDI coil (the coil wire screws on to the boot and does become burned (arced) out at the boot/plug cap connector. WJ-CZ sell new boots for a rediculous price, but still... cheaper than not flying. The other part is the regulator/rectifier.. and they DO go bad. I will post asap0: if/when I resolve my own "weak-spark" condition and let you know what part(s) resolved the issue. Regards, queqqq
