OK, how about the same question but this time with a ringed-engine, OS .50SX? Is it just a crucial for this engine as it is for an non-ringed engine to get the connecting rod in the same direction?

And I needed to take this engine apart because the heavy varnish on it was unusual for a low-time engine. I run WildCat 15%. When I removed the head I noticed the varnish was also present under the head -- it seams this engine has been leaking from the top. Now that I recall, the head bolts and backplate bolts came off without the normal starting snap -- they must have been loose.
