OK Ben, it has arrived. Interestingly the ABITAR came with no muffler and Conley came with a straight pipe and a muffler that bolts directly to the head. The top of the piston is clean and dry and the glow plug threads have not been violated. I gotta think about whether I want to run it or not, nah, of course I'll run it, if you don't run it it's just a bunch of parts that look like an engine.
