Cap,

I know why the insulator block is there but I guess I didn't make myself clear. Here's the point. Because of the angle of the opening in the block and the intake passages, one can't see into the cylinder or crankcase. I meant I'd remove the carb and block to satisfy my curiousity if the engine was mine.

I've been building and modifying engines for most of my adult life, so I'm not afraid of a little disassembly.
