Hi all,
I'm having problems setting up the twin SU HIF6 carbs on my Rover P6 V8 engine. The car drives fine when cold on choke but when warmed up it's reluctant to pull above 3000 rpm. Pulling out the choke again at this point and the car runs fine suggesting its running too weak? However no matter what I do with the carb mixture screws (turning them clockwise to run richer) it makes no difference. I have checked the jets in both carbs and they do raise and lower when the mixture screws are turned. The fuel pump is electric, ECCO model 1.5 litres/minute, 3 - 4 psi which appears to be correct for the carbs. Any suggestions on what the problem may be would be greatly appreciated as its driving me nuts at the moment!
Cheers, Rob
