there are no caps on my mixture screws to limit how far you can screw them out ,i have tried to syncronise the carbs with vacum gauges but didn't work ,the workshop manual says that the pilot mixture screws have to be set before syncronising but as the screws come out from the bottom of the carbs and they're behind the inlet manifolds they are diffacult to get to ,gonna try using a cut down dumpy screw driver today ,but not very hopefull ,thanks for the reply
The pilot screws only control the supply of fuel to the idle air flow. Based on what you've said about the carb synch not working, I believe you have a vacuum leak (assuming it's not a bad synch gauge), most likely at the large O-rings at the bottom of the air intake elbows.
