Gas ez go motor identification

[atysi10]

how do I tell the difference between the 290 engine and the 350? I can't find a stamp on the motor?? I also don't have anything on the cart to tell me the year, the cart was converted to a ball picker and I think they removed the plate.

there should be an air shroud on carburetor side of engine with EH29C or EH35C. Other than that the only way i know is the 295 has a 64mm cylinder bore and the 350 has a 67mm.
