Power valve seals

Hi can any one tell me if the power valve seals are the same on the mc21 as those fitted to the 150sp head i.e from the 300 kit.
I found the part number in the parts manual for a 250?

I didnt know the cylinder head on a 150sp had a power valve seal. Very Happy

Well when i removed the power valve there was a round seal on the shaft just behind the cable guide. Same position as this item
