Status: offline 		oh ok I see it now...likely the one on the right is a newer version....it is not uncommon to find little tweaks like that in model lines...it is done to shave more weight.

So is the head on the right or the left the newest version of the 3.3?

Status: offline 		^^^It depends on how you care for the engine. Some have blown bearings at 2gallons,I have my first 3.3 and it's at 8gallons and the rear bearing is starting to wear down,I'm gonna replace them when I get the cash.

Status: offline 		Yeah left is new head, right is old.

They replaced the cheap chinese made bearings with some nicer german made ones so they should roll better and last longer. Particularly the OWB.
