In this post I clearly see the carb. is new, but the parts on the electrical is confusing... Have you replace those or just some?

happyjak · 07-25-2010, 09:28 PM

all new electrical parts,coil ignition, pulsercoil ,volatge reg. ,ignitor ,solenoid, got the parts from ezgo.

Aye Carumba!!! Well that about covers all the ignition!! Let's try this... A new part does not always guarantee a good part, and we know we only have fire on one cylinder. We'll put the lean condition on the back burner til' we figure out the firing. Start with the plug wire itself. Remove the plug and insert in into the wire. Ground out the electrode on the plug and mash the accelerator ( with cart in neut. or on jacks ) and see if you see any fire. If not, remove the wire from the coil, trim the end, and inspect the inside to look for defects. If all is good reinstall the wire and check the plug end well and repeat the process of grounding out the plug.... I have never seen one side of the coil go bad, but I guess it is possible... Hope this helps ya...
