hello mate
best thing to do is get you self two haynes manuals
1, ford capri or any car thats got a pinto fitted if you haven't already got one.
2, weber carburetter haynes manual.
the ford one should show you how to remove and replace the old carb and manifold, but just substitute the new carbs instead of refitting the old one.
and the weber manual will show you how to overhaul and tune the DCOEs.
hope this helps
RegardS nick.
