When I bought my 149 I knew it had a fair sized oil leak (wet, not caked on dirt). I haven't run it much so it hasn't been a high priority to fix. Checking it out it looks like most if not all the leak is coming from around the governor shaft. It has some play front to back and not much up and down so I figure the bushing is worn. The problem is I think I know something on this. I think the cause of most leaks is mostly pressure in the crankcase finding it's way out. I don't see a breather tube on this engine but, I have seen looking online that, there is a reed valve that can let pressure build up in the crankcase. I haven't checked the compression so I'm not sure I don't have blow by. It doesn't smoke at all for what that's worth.
So what do the better heads than mine say? What do I do first?

Thanks
