That sound acceptable to me using that type of tester assuming it winds over near 250rpm test std. Anything reading around 90psi on a normal gauge should not cause plug fouling.
Have a look if you have a leaky secondary fuel injector on the front rotor, you can check this by taking off the top half manifold and simply priming the fuel pump. This is/can be a common cause too.
