Thanks, I wasn't aware that MVVS did not sell these as a diesel variant, although the diesel carb certainly looks well made, and the diesel head is outwardly identical to the glow version. However, I would still like to obtain a copy of the original manual for this engine, especially considering the operation of the older style glow version carb. I most likely will be operating this engine as a glow unit, although I'm what you might call "diesel curious".
