Decided to take a look at the Victa Corsair again. Took the starter mechanism off and found that the o-ring that sits under the Starter housing assembly was broken and perished. I've taken off the cylinder head to examine the cylinder and it actually looks ok ie just a little bit of scoring. I can't see much of the piston but what I can see is a little bit of brown possibly burning on it. I had a go at trying to take off the crank pin just using a hammer and screwdriver but it did not budge. Suspect rings still but need to get a closer look at the piston.
