This is the progress so far
Not very good photos sorry.
and this is the offending engine.
I had my suspicions about the engine so last year i bought a short block from Chris in Honiton it had been re bored and I had the crank reground.
at this stage now the unleaded hed will come off the other engin as will the flywheel with it's pre-engaged starter. I will get that done after i sort out the changes with the DVLA
