that's information! Thanks, Rick. I had what I thought was a
glo-plug longevity problem in the old Jekyll, until I put a header
tank in it. The lean burp always seemed to be at the throttle-up into the
vertical "8" from the figure "9" in P03.</FONT></SPAN></DIV>

it might be fuel foaming causing a lean condition in the air? I had that
on my Elan early on Never identified the lean condition by sound, but
had some plugs blow seals etc and plugs lasted about as you described – a
2”x3” chunk of foam in the right place around the tank solved the problem.
