It's all very easy, buy a carb rebuild kit for starters and install most of it. when you come to the power valve diaphragm (it's easy to spot because it has a metal disk on one side and a thin metal rod on the other) you will note that the thin metal rod comes into contact with a ball bearing type valve when manifold vacuum falls below a certain level. Snip the rod off flush with side cutters and install the diaphragm as normal, now the valve cannot be actuated. At this point you may as well leave the other circuit working as the problems only arise here if the rubber is perished and enrichment does not occur at normal running temperature anyway. To remove the cam is a simple process on most webbers, undo the nut on the end of the shaft, slip the cam off and replace the nut. On the later XF's '90-93 utes the cam was crimped on so it's easier to adjust it's profile with a file than it is to re,ove it.XE Falcon said:Thank's edv8, sound's to me like a good reason for the sluggishness. Is it a simple process to disable the circuits? Also im all for economy but removing the cam from the throttle shaft doesn't sound like something i could manage, what would i have to do if you don't mind?
Thank's for your advice!
