Fouling plugs? Update 9/2/08

[THEFERMANATOR]

That 150 looper you have WILL foul plugs on 40:1 at low RPM's, not much you can do about it. The VRO ran them at 100:1-150:1 at idle to prevent plug fouling, but they would go to 50:1 at around 2000 RPM's and then to 40:1 above around 5000 RPM's. I would use a semi synthetic like PENNZOIL offers and mix it at 50:1. A regular dino oil at 50:1 will still foul plugs more frequently than a synthetic blend or a pure synthetic.
