Thanks to all who have posted
no worries,but if you ever are struggling for bits the lizard guys have very many engines stripped for bits as these engines were common in small fishing skiffs.

when i sent the crank to paul in nz the postage was 17,and the conrod sent express was 11.

FYI

another thing that the lizard guys pointed out,about the YSM-E-B series of engines as the main cause of failure on these engines is loss of oil pressure from wear on the front cover of the oil pump by the rotor.

this can be rectified by refacing the cover and pump housing body mating surfaces untill the rotor is nice and snug in the housing again.

they also reccomended using a classic sae 30 mineral oil,and not a synthetic oil for lube

Thanks for the heads up re parts and oil pump issues.

The oil pump was the first part I overhauled .

I had the bottom surface milled flat again, the shaft hole drilled slightly oversize so it was round again, a new shaft turned up to match the new hole. The cover milled flat and the top of the case milled parallel to the bottom surface to get the rotor clearance spot on.

At least this aspect is ticketey boo.
