I bought a piston which was listed as a genuine OEM Lawn Boy F engine piston. The seller claimed the first 2 sold were genuine Lawn Boy and the rest were OEM spec aftermarket. I bought the 2nd one sold so I should have a OEM piston but I don't know how to tell for sure. Pics of an original piston are hard to find to compare it to.
Seems all the pics I have seen show a dimple in the middle of the top of the piston and the one I bought doesn't have that. I will post pics if anyone can tell me.
Hmmmm, yes, my Lawn-Boy Mechanic's Handbook shows the dimple, but the pics aren't great. Does the box it came in have the O.M.C. logo on it? If yes, I'd say it's O.E.M.

Inside the piston says USA and it also says BTM where the wrist pin goes. The top of the piston has a slight dome and the middle is flat, no dimple. Not sure if they changed the part number at some point or if there were more than one piston for the F engines?

The box it came in doesnt have anything on it. It just has a sticker with the numbers... 924923.

I am going to say this about picture number one. The area that looks like someone has put something in it to hide something tells me it is a fake. I have put lots of pistons in and that recessed area never looks like that. They where car pistons.
