Satoh S650G

[Clonephoon]

I have a 1970 ish S650G that is only running on two cylinders when the plug wires are plug in completely. And runs on all four when two of the wires are just sitting on the end of the plug.

This leads me to believe I have the wrong spark plugs in the tractor. Currently I have NKG B8ES plugs with new wires, cap and rotor.

Are these the correct plugs? Or does anyone have a preferred plug.

Well since I got my B2910 Kubota the old Satoh 650G has been sitting.....

When it was last running it had "NKG BR7ES".

You could have a couple of defective plugs, or plug wires.

Good luck finding the problem. I really did like the old Satoh until Kubota arrived.

The correct plug is Champion N4C or equivalent. Call 800-609-5110 for tune up parts for your S650G. I stock everything you need at local auto store prices.
