2510 sleeve replacement

[ajo]

I"m in the process of rebuilding a 2510 gas engine. purchaced a rebuild kit . the are no instructions for the placement of the o-rings on the sleeves. the kit includes 2 flat rings and 1 round. it is and early block with no grooves and the sleeves have only 2 grooves. the upper looks like it is for the round ring with the lower for one of the flat rings but where does the other go? thanks

I believe the colors of the orings go on opposite of john deere if it is an aftermarket kit. It would be a good idea to check with the tech support of the manufacturer of the sleeves.
