    Fuel screw

    OK, I've spent 2hrs searching the forum. I thought there was a picture or a description of which screw is the fuel screw in a previous post. The turbo's fitted and in getting a new exhaust s now I want to "tweak" the fuel but don't want to accidently "tweak" the wrong screw...anyone help?

    PS. I think its under the bottom big cap at the rear of the injector pump (lockwired). Am I right?

    I just happen to know a bloke whose got the EMEI's for that particular engine, not far from you.

    I reckon you should get it all together get it settled with the stock fueling (make sure nothings leaking) then go see him...

    Why would he need technical information, to find whats in the pic above and turn the screw?, just needs a pyro and a big hill or heavy trailer

    Oh a boost gauge and leak of valve for boost adjustment would be nice too

    for all the talk and excitement expressed about the fueling screw, its actually a disappointment once it is located.

    as in the picture above its a threaded rod that is out side the pump, all it is a stop for a cam that is just a small bit of triangular 3mm plate the size of a 5 cent coin.

    The other two big screws that you asked about is max rpm and idle speeds

    Leaking...? It's got a few oil leaks, some are more like oil flows! Gaskets ordered, searching for better unions. Sounded cool driving to the exhaust shop but!
