I looked at my BT64Ei and noticed the plug wire is not shielded. I have been reading about rf interferance and I am concerned that it may be a problem.
Now I know that more people will take time to persecute than to praise so my next question is what percentage of Fuji engines have a problem with this

1) Where can I get a shield and metal cap
2)what percentage of Fuji engines have a problem with Rf interferance
3)The manual says use a 22-12 carbon prop at what rpm does it turn this prop

Fuji doesn't have such a plug lead. However, you may be able to get such a lead and cap from a small-engines repair shop. We don't have numbers of engines that may have had a bad EI unit with RF leakage. The manual states that a Bolly 22 x 12 Carbon prop was turned at 7,100 RPM during their testing.

thanks for the quick reply have you had any complaints about noise on 50mhz
