That engine is only about a 1/2" taller then the Honda, or clones.
Landshark55 that engine has a bad flywheel, and crank. The newer Champions have thicker flywheels, and stronger cranks like the Honda.
I just don't like the shaft mounted rocker setup the new Champions have. It's the only clone to have them. The only bad parts about all the clones are the weaker rods, and rings.
Some clones have factory stronger push rods, and rockers. Stronger then the real Hondas. (If you buy the correct one)
