Thanks Grumpy I did some checking on the engine and I am now pretty sure the rings are stuffed.
On a separate note since we were talking about loose rod bolts I thought I�d add a couple of pictures. It is very interesting to note the bolt connecting the rob was loose, supports Joe�s comments.
The engine had plenty of oil when it came into my possession. I was pretty sure it was stuffed and the photos supported my findings.
I have completely rebuilt a number of two strokes however I haven�t split a case on the briggs engines before so I�d appreciate some of your comments around each of the parts and key things to consider about repairing the engine. I have watched a few videos and it doesn�t seem that complicated but I have no doubt there are some special things I should consider like usual.
At worst out of this exercise I have a perfectly straight crankshaft that might come in handy for a future project.
Oh and I haven�t got the piston out of the bore yet.

Funny point - I have never snapped a boss - they must be made of rubbish
