Not. There are tons of us running metal rods with nylon ball connecters on the end, without interference. My bet is on the cap not being on all the way. If you don't push down hard on that sucker and feel a good solid snap it's not on all the way. Again, read the gas engine for noobies sticky and make sure your running your radio in range test mode to really make sure you have the issue fixed. Change one thing at a timeuntil you have eliminatedall the possibilities. Anybody remember the old days when your car radio would make ignition noise? It was a sure sign you had a leaky plug wire or cracked distributer cap.That went away when electronic ignitions became std on cars.

That metal pushrod to the carb acts like an antenna regardless of any type of connector you use. It passes through a strong electromagnetic field that exists around the engine, ignition module and any other component of the ignition system. In fact, it is a better antenna than the one in your receiver because it is much longer and the field strength around it may be higher. Dan.
