BlackSeven Posted January 8, 2017 Share Posted January 8, 2017 Keith assuming you have a stock Blacktop and the 5 progression hole Webers I can help you out with some tried and tested jetting; I will pm you when I've had chance to look.

keith.rose1 Posted January 8, 2017 Author Share Posted January 8, 2017 Thanks RobYes it is a blacktop, with 45 DCOE. However they have 3 progression holes, assuming those are the ones under the blanking plug by the pump jets and idle screw. Middle size of the 3 is 1.0mm dia, so I assume they are 80, 100, 120 Keith Link to comment Share on other sites More sharing options...
Matthew Willoughby Posted January 8, 2017 Share Posted January 8, 2017 I would take it to the rolling road at Northampton Motorsport. They are Weber dealers and specialists in tuning them. Link to comment Share on other sites More sharing options...
BlackSeven Posted January 8, 2017 Share Posted January 8, 2017 Keith, I think the only way that you will get the progression phase anything like acceptable with 3 hole 45's will be by using massively rich idle jets /air bleeds to mask the problem of too few progression holes.Before you spend good money on a rolling road set up I'd look carefully at the cost of swapping your 3 hole 45's for the zetec specific 5 hole 45's; I got a pair of the 5 hole ones brand new for around £650 and you should be able to get over half of that back on Ebay for your existing carbs. I will also share my 5 hole jetting wth you which took a good few hours on the RR to perfect and works surprisingly well. Rob Link to comment Share on other sites More sharing options...
