somebody jump in & correct me if I am wrong......
since the pull starter is on the opposite side of the out-put shaft, this is a full crank engine. (2 crankshaft bearings....a good thing!)
On most little engines, behind the pull starter is the flywheel, which also acts as a cooling fan/blower. (This is why we need to keep as much engine shroud intact, as possible. )
I think /hope this is the case.
