Hi CyberJack,

Wish I could proceed, but since swapping over the crankshafts the engine has lost all of its compression. With the previous crank there was a lot of resistance. I don't know what I have done wrong, I may have accidentally switched the tappets and now the valve clearances are incorrect? It is too easy to crank and I need to put fuel into the spark plug hole for it to start. Would an air leak in the sump gasket or oil seals also cause a loss of compression? I am also so wondering if the journal offset is a different dimension and if I need to change over the connecting rod too.
