Mounting an engine inverted.
I will be mounting a Saito .91 4C to the GP UCD in the near future. The instructions call for mounting the engine inverted. This would be my first experience mounting an engine inverted. Are there any problems I could expect mounting the engine this way, vs. sideways or upright? Would the engine have more tendancy to "load up" while inverted? Can a new engine be "run in" while inverted? Any advice would be appreciated. Thanks!!
