did you have the flywheel skimmed bfore fitting the 6 paddle?
chances are it will get better with use, but with a paddle it really needs smooth faces on both the cover and flywheel to work nicely.
i think msd have pf09 (4x4) tps in stock....
ps, bont be fooled by the colour either, there are both red and black 2d and 4x4 ones about, its the part number that maters,
PF09 4x4
PF01 2wd.
