The carbs are jetted different left to right due to the airflow in the airbox
not being uniform. dont mix this up with the pressure , just that the intake to
the air box is on one side so the volume through the carbs is not exactly symetrical.
Are you running an intercooler? What can happen is that at very low intake temps
the fuel does not atomise correctly . In your case just check the fuel pressure
is rising ( regulator is ok ) then observe the egt.
Oh check the threeway solonoid valve which richens the mixture up at high power
settings. You should hear it click on the ground if somone opens the throttle
up , engine not running of course. This is situated on the airbox on all but
the early engines.

that indicates to me that fuel injection would be a lot better ;-)

Kev,
I was running an intercooler but took it out today to check this...problem is still
there. I have not checked the solenoid valve and will do so. My EGTs all
read normal at all throttle settings except full but this is hard to determine
as the rpm is fluctuating so much at full throttle. I did try to pull the
choke to see if a boost of fuel would help the problem and it doesn't. Based
on my Bing tuning manual, this is a method to determine if the engine is running
rich.
At this point, I am at a complete loss as to the root of the problem and it is
very frustrating. I am half tempted to pull it off and put an IO-240 on regardless
of the weight penalty...
