gone back to the drawing board took it all to peices again,found what i think could be some of the problems
undid the four hoses of the breather box on top of the plenum took it of the plenum tried to blow down all four tubes the two of the big ones where fine but one of the small one was completely blocked, i have cleaned all the pipes and channels with carb cleaner loads for crap came out, all clean now could this small blockage be part of the problem?

Thanks , it was poor before i found the vac res pipe fitting was broke as i said before i thought i'd fixed it how will i know if thats the problem and if the multi rams are working ,would that account for the total loss of power it is driving like a old slow tractor.
