What I did today was leave behind all of life's excitements and demands, and return to the workshop. A much inspected and hopefully thoroughly cleaned crankcase, and new larger dia oil pump. Larger dia jet plugs due to various experiences removing old and unimpressive jets, then testing. Much oil circulated, so that's what the jets look like squirting merrily in the crankcase! Pressure reading high, but 18psi is significantly better than 2psi, also revs from drill probably more than off the end of the camshaft. No evidence of cracks anywhere in the crankcase. So now let's put the thing back together and proceed. Is the easy way to slot the gear onto the key in the drive by offering up the pump drive shaft from below?
