I'm going to put a radial engine mount for a Moki 1.8 on a Sig Cap231ex. However, this plane requires some right thrust. I plan to put some washers under the left to increase the right thrust. Is this a problem? I have heard that radial mounts need the circular part to touch in every spot for stability. By putting in the right thrust....this won't be possible. Any ideas or comments?

Thanks for the help.
