NGK has had a problem this year with a few batches of plugs.

I was talking with a guy at the last store I purchased plugs at. Told him my story about the three plugs I've found bad. He told me to bring them back and they'll give me new ones.

At that store they set up a make shift spark tester with a coil and a power source checking the plugs before selling them.

I guess NGK will take the Bad plugs back but will not call back all plugs during that production. Only returned plugs.

So here is what happened. I started lookin over the wiring, and had found and replaced some bare wires. No help. Last week I found a rectifier on Ebay and ordered it $29.99 to my door, (it was a used item). Plugged that in this morning and kicked it over and she took off like it was a race. Both cylinders fire, good throttle response, but now on to the next problem.......
