OLD_SLOW and in the WAY

heres a few pics of the insides. in the cylinder picture notice the small angle at the transfer port . this was put in to give clearance for the 26mm wide exhaust port this is to stop short circuiting .... or the gas escaping out the exhaust port instead of going in the cylinder.
This engine comes with a kill switch but i grafted my tach wire to the spade connection.
I ran this engine with a 27 and the old style 25cc cylinder last year. and proved to be very reliable and powerful.

enjoy
