    No other markings. Thought they only went A-D. Came with an A piston second hand. image.jpg

    Dunno mate I'd say one I'd the early 7 port ones as has bigger PV's with drain hoses. Not sure when they went from 5 to 7 port?

    so spare 125/144 cylinder? Not your 165? Didn't know there was an F either.

    Okay, here you go, husky used to size cylinders A-B, C-D, & E-F, these would be equal to today use of A, B, & C. In other words your old "F" cylinder is equal to a "C" today. That is why I asked the year of the cylinder. In reality you can use any piston in any cylinder as you saw with an A piston in the motor.

    Ahh rancher you are the man! Appreciate ya passing on the info mate. I was actually thinking something along those lines(probably read it here before!). Thanks mate. The A piston it came with feels a little sloppy in the bore? Might just be me though.

    Old ring that came with it was 0.5mm about 10-15mm below top of bore(pushed in square with piston). Was thinking 125 should be around 0.3-0.4mm?
