Actually, it's not an X, so it'd just be for practice.
This engine was given to me many years ago and today I decided to see if it'd run.
It runs but blows a lot of fuel.
I disassembled it and see there's no crankcase/cyl base gasket.
Doesn't seem right, but what do I know?
Should there be a gasket?
Never mind - I found Warring's review which states that it does have a gasket.
Time to break out the circle cutter.
