You can't see in the pictures, but 3 of the JV's have less than 1/8" of threads from the adjuster sticking out where the 2nd from the front is a good 3/16". That is the oil covered plug apparently. That jet valve was all the way out because of the position of the cam and not touching the adjuster at all.

Might be able to see the difference better in this one:



I'm not necessarily against removing them, but it would be less work if I can just adjust them and go I am hoping.

I'll probably throw a new cap on with new plugs and go from there, the orange wires you see are actually replacements from the last ignition issue I had.

Anyone have the JV specs handy? Maybe just adjust that one to what the others are and try that first?
