Hi Daz, took the bottom brass nut of two units, skooshed copiuos amounts of WD 40 into where the fuel enters and down the pins, bingo, one pin pulled out no problem. Not tried the better unit but hopeful this can be achieved without taking them apart. Having rebuild one at least I know what I'm dealing with so might be lucky. Got new ABS belts and rive shafts in, hubs and brake disc & calipers on.... have to take half of it to bits tomorrow to get the soddin anti roll bar on,lol. Boy it's fun. Photos manyana.
