I have a 46cc poulan convert. At full throttle it interferes with my radio. Would a throttle servo mounted in the front, 6" behind motor just inside the fire wall cause this? The receiver is new and it is FM. I do have a PCM to try in its place. I hate to mask the problem with PCM rather than find the problem and fix it. The engine does have a resister plug and standard ignition. Any thoughts or opinions?

Thanks
Shan
