Hi,

I am experiencing some rough running at high RPM when the car is hot, it is 
felt mostly through the clutch pedal. I am trying to locate the cause.

How often do people replace the fuel filter? maybe I am experiencing fuel
starvation at high rpm's.

Has anyone tried the ultra or NGK wires? do you notice any difference? 
and at what rev' range? what made you decide to replace them in the first
place?

I also advanced my timing to 14 deg. Maybe this is too much with my BBR, 
perhaps I'll back off to 10 to see what happen.

I am also getting this metallic squeak that I can't seem to get rid
of. I lubricated the hood latches (front and rear), door hinges and latches
to no avail. Does anyone have other ideas?

thanks and have a good W/E. Don't forget the Fall Vintage Festival at
Lime Rock.

- Steve.
