Some engines have defects, don't expect any O.S. engine to be better in terms of reliability as the Nova, as O.S. engines have problems as well.
I have a OS Speed 21XZ-B (new) in another Mugen, and still not starting. We all know that there is no perfect engine, all brands have their problems.
I think I'll buy a Bonito XLB, so I can use the same set of pipe and manifold.
