Thanks Norm for that info, I might have to go find him and pick his brain, In the mean time i have found the number of the Engine, so was able to decipher them
So i now know my Engine was built in May 1970 Ive also been able to identify the Carby, and parts should i need them, Im about to go try to make a gasket for fuel bowl
which should solve most of my problems i hope

cheers
