Hello all!! In the course of trying to fire my problem child 494, a rotary valve timing question occurred to me.
With the air cleaner off of a carb, throttle wide open, rotating the primary clutch counterclockwise as viewed from the pto end of the crank, and looking through the carb throat with a flashlight, which direction should the piston be moving when the rotary valve is open for a particular cylinder? The little bit of 2-cycle theory I know thinks the piston should be travelling upward to create vacuum to draw the fuel-air mixture in from the carb. It is currently travelling downward. Am I all wet, or does my rotary valve have serious timing issues? Profuse thanks for any and all assistance, Kenneth Kirkland #18 MiDiv / Arkansas Region (77) 1991 KBS Mk.
