[RFI] Gas generator ignition noise

[Missouri Guy, N0TT]

Hi Gents,

Field Day is just around the corner and my 1967 vintage Sears
generator is causing ignition noise on all the ham bands.  The 
ignition coil recently had to be replaced and the only replacement 
was one with a wire lead instead of a resistive lead impregnated with
carbon.  
The spark plug is the resistive type.

I was thinking of using some hi-u ferrite beads over the ignition wire
to reduce/eliminate the noise, especially on the lowbands.  Has
anyone tried that?  And did it suppress the noise for you?
