wooo hoo think ive nearly found out what was wrong i did as moonie said and on no 1 cyl the com was slightly low so i took the rocker off and the little thing that sits in the rocker was shatteres into 3 peices hence the low comp so i thought id look at the lifters out and have a look at the cam,well it well fooked on no 3 so bettween the two this has got to cause the slight missfire yea? i mean on 3 there wasnt even a lobe there hardly

so im on the look out for a std rst cam in good cond if u know anyone cheers
