Thats the way they came fitted up on the manifold straight from another guys car, (Shandylegs) has already posted that they are mounted back to front,and I,ll probably burn my hands setting them up....
I bought the whole engine off the lad just for the top end and carbs,cam,vernier etc,
and judging by how black the pistons where I don,t think he even bothered setting them up..I don,t think he really had a clue,thats why I stripped the head and completly and rebuilt it ..

Thanks for pointing that out guys......I,ll swap them round...Iam going to get another weber carb manual ( like i did last time)..and tune and balance them,and once its complete and running it,ll be straight off to be put on the rolling road..
