    Thumbs up 4age carb how to?

    Ok, so i've been contemplating the use of carburetors on a future build and summing up think it's a good idea. carbs= no overly expensive management, good response with the right tuning, easier (don't quote this though) to tune than an ecu, and you still get to hear that sweet sweet induction noise without mucking around with ITB's. converting a 4age to carb sounds relatively straightforward and I'm sure a couple people have done it on here so please show a run through of how to convert to carb.
    oh, and i like pictures
    thanks.

    Not overly hard to do.
    What you'll need:
    A manifold. Redline make these ready to go to suit sidedraughts for Big and Smallports
    You'll need to thread the injector ports, and block them off
    You need a low pressure fuel pump,and regulator (around 4psi)
    Then you need to think about the ignition setup. Couple of options : A brand new distributor made to suit with centrifugal advance, or use the standard distributor with this

    and then playing around with setting up the linkages.
    I'll post up some pics, any more info you need?

    I haven't got any pics of it going together though unfortunatley.

    The manifold doesn't come with any mounting hardware, so I had to source studs.

    might also be worth looking into if your collecting up bits for a carb setup.

    What about carb choice?
    I worked it out a while back, I reckon ideally you'd have 43mm throttles (from memory). From a choice of either 40mm or 45mm dellortoes, which would be better? Better low end with 40's, better high end with 45's?
    I guess what I'm saying is, could you use 40mm dellortoes if you werent after high revs

    40 seem to be fine for use with standard cams, 45s for aftermarket cams. Depending on the jetting
