That eleminates the fuel.
Remember "Sportin' Life in

It could well be you made the problem worse by going to the 20% nitro. Depending on the age of your FA-150 you might have one of the "High Compression" versions, they can be really critical on nitro percentage. Try using some fuel with zero nitro, or at most 5% and see what happens.
Also, reset your valve clearance to 0.0015" at most - that helps too. And yes, that is one and one half thousandths inch, not fifteen.
