No Spark!! Ugh!?

[Hunter65]

My Honda 110cc 3 wheeler engine that im putting in my kart has no spark. I have tried 2 plugs one new and one older but still no spark. What else would cause me to not have a spark?

If you already have it mounted on your kart, I would recheck your wiring to make sure you have 12v where it to everything. after that maybe the ignition module if it has one and the coil and stator.

Do you have a wiring diagram of the 3 wheeler that would make hings a lot easier.

Maybe someone else here can tell you how to check each component.

Here's a thread from another forum listing serveral possible solutions: http://www.dfwstangs.net/forums/printthread.php?t=350864

Ok well read that and it didnt help too much. I was just out there and the thing that the spark plug wire comes out of (i think its called ignition coil or somethin) Has sparks coming out of it when one of the bolts coming out of it is grounded but thats it.

One of the guys in that thread suggested to make sure the coil was grounded. If I'm understanding you corectly it sounds like your coil isn't grounded for some reason and you just need to figure out why or supply a new ground source. I'm guessing it might have something to do with rust/corrosion between the coils mating surfaces and/or loose mounting bolts. If the coil is rubber mounted, it may have an external ground wire thats just lost its connection at some point.
