thank you so much for all this helpful information.

when my motor is at TDC the decompression shaft is on the right position (like the second picture you uploaded) same as the camshaft notch.

but the decompression pin (#3 on the first picture) looks like it is with the little slot on the edge of the pin is facing up, while in my motor the slot is facing down when at TDC,

assuming this picture (first one) is illustrating the cam and pin at TDC then my motor decompression pin is upside down.

on the second picture you uploaded i can't really see the where the slot on the pin is facing.




this is my motor decompression pin at TDC, if you can see, the little slot on the left edge of the pin is facing down, and in the sketch is facing up.




is it possible to pull out this pin without pulling the cam out ?
