Lol you guys are AWESOME!! Thanks for all the info, the rental guy was pretty honest and said its been out 95 times....it deffinatly looks clean and it's only 30 minute drive. I have a compression tester so maybe I will go have a look. I really like that 362 though.....I can easily wrench on the saw I just don't want to end up having more $ into a used unit then a nice smelling new one. I raced motocross for 12 years most of them on a 2 stroke so I am well aware of the issues improper porting can cause so I will be avoiding the mod urge! Not to mention the cummins is getting a little crazy lol one thing always leads to another haha!
