I would advice you to go with SAITO FG-40 as a superior replacement.
I have Saito FG-36 one and extremely happy with engine.
Saito FG-40 is in the same size and weight as 36, but 4cc more powerful.
Saito used 36 one as a base and then widen cylinder and piston in order to get 40cc.
I have many Saito engines and I can tell you they are very reliable marvel pieces of equipment.
OS just entered that 4-stroke GAS market last spring and look like they didn't test fist 4-stroke gasser well enough.
Saito 40cc is a bit heavier compare to 40cc OS, but this is the only disadvantage.
