Hello,there... Ive been searching high and low for any info on how to wire up a 250cc manual shift atv engine that I've dropped into a Chinese off road go cart. Hope you guys don't shun me for my ride not being a scooter. Anywho, I've got the engine in and everythings all connected, battery, throttle, clutch, shifter, everything... I just haven't been able to get the damn thing to start. Actually, that's not accurate, I did get it started one morning before work but I'd only been loosely connecting wires in different sequences according to diagrams with similar setup, hoping I wouldn't fry anything, but when it started up all the electrical components were resting on the rear tire, they vibrated off, everything disconnected and I haven't been able to reproduce the same sequence again. It's pissing me off. I've got 2 pigtails from my engine like the one discussed in this exchange - 3 yellows from the stator grouped into 3 prong plug and another plug with 1 green and 1 blue. Bought the engine new, a 167fmm, and dude at the shop said itd take an AC cdi, but after lengthy research I've concluded he was wrong based on the wiring coming outta the engine. I gots no freakin red/black wire anywhere, just the ones mentioned. I've got all components, in fact I've got 2 sets of everything... Dc cdi, solenoid, rectifier, and coil. Only the rectifiers are of different types, one a 4 wire and the other a 5 wire. I've tried several times now using different diagrams for dc systems, the best coming from a site called Lambertsbikes.co.uk, pretty good drawings and info, but I'm still not getting a spark. Not sure why, haven't then a voltage meter to anything yet. If someone could help me to get this thing wired up right and started, I'd greatly appreciate it.

3 yellow are 3 phase charge windings to rectifier/regulator. Your 4 pin R/R is most likely for a single phase stator. Single phase setups run headlight and tail light on AC to reduce load on R/R. I went with a 7 pin R/R since there are multiple websites showing how to wire one up. ( no such luck with the 5 pin....) The green wire on engine is stator ground ( trigger coil ground and ac cdi charge coil ground if cdi charge coil present.) The blue wire on engine is the trigger coil.( goes to cdi to trigger spark at sparkplug ) Not present red w/black stripe wire is high voltage charge coil for AC cdi. ( your stator can only be used with a DC cdi. A DC cdi includes a dc-dc inverter to generate the high voltage for the cdi. ) To test DC cdi: connect 12v, switched 12v to 12v, grounds, ignition coil with sparkplug to cdi. ( see picture fo pins.) Don't forget ground for ignition coil and plug. Do not connect blue wire fom engine, insulate the blue wire terminal. Using a jumper, alternate connecting trigger pin on cdi to +12v and ground. You should get spark at sparkplug. If Spark, remove jumper, connect blue wire to cdi, add gas and start engine. ( might help to connect carb enrichener to switched 12v to prevent mixture being rather rich after warm up )
