yes its always a fantastic feeling hearing that motor tick over for the first time.
My experience had Jeff Taylor in histerics, as the motor blew a heap of smoke (due to worn guides and left sitting for 7 months), with him saying "ah... its a pig!!".
Kind of a bitter-sweet memory for me and very humbling experience.

BTW, the engine didnt turn out to be a pig the thing soars to 8500rpm with no problem. Next time out I may push to 9000rpm but I may run out of track!!!
