Its far cheaper and stress free to take the diagnostic approach with K-Jet than just replace bits.
Thanks for the help mate. I rwplaced most parts because the xar was stood for 5 years before i bought it and it was abit of prevention to what could go wrong but i think most of my problems were from the fuel metering unit affecting the mixture.
Will the fuel pressure give me the answer I need?
Also what is the best way to test fuel pressure? I have never done that before
