Good luck and be patient, it is well worth the wait. Also another tip, when you're cooling down the motor between tanks make sure you put the piston at bottom dead center or BDC as the cylinder is tapered and gets smaller at the top vs. the bottom, this will give you higher compression and longer engine life from what I've heard. What I do is take out the glow plug and rotate the motor, watch the piston move, when it's all the way down at BDC I mark the flywheel with either a screwdriver or sharpy (which *will* wash off) that way it's easy to find BDC without taking the glow plug out again..
Interesting, mine came with a grove mark.
