what is this peice called?, it goes in the notch in the inside circle of the engine sprocket and keeps it from sliding and slipping on the engine, below is a picture of what im talking about
thank you so much, you guys are a big help, i was needing another woodruff key because i lost the one on mine after changing the old wore out engine sprocket
Be warned that the Chinese kit engines use different sizes and shapes of keys
and that they are not interchangeable

Sprocket shaft diameters may be different too

What is it with you guys that post the same question on both forums? :D
