Some people need to stay away from motors and giving advise....
At least someone got it correct. Behind the carbs is the intake manifold and sometimes called the reed plate. If you remove the carbs you will see the reed valves or peddles. They should all be against the reed block, the part the reed rest on. If you see a large gap, the stand off to bad, if you see one missing, you got a problem.
Please... Loop charged combustion chamber use intake ports that move air/fuel around 3/4 of the cylinder thus using the incoming air/fuel to scavenge the combustion chamber, they still have reeds. The 2 types of motors that don't have reeds are a piston port, use in some dirt bikes and lawn equipment and rotary valve used by Rotax in Sea-Doo watercraft. The only one left is cross flow the uses the dome on the piston to help scavenge the combustion chamber.

Cross and loop scavenging methods are not the Ish-shoe here, my spelling is ! Mercman is got it write, that's were they are and that's how you get to em. Look to see if a screw is missing from the butterfly, If it is you can bet it's lodged in the reed. Like merc said, check the stops, the reed has to be flush. Check for hair line cracks with your flashlight. Don't think that's your problem, but now that we're this far you might as well check. I see you haven't got a service manual yet? Oh well, I guess it's worth the laugh, some of these answers? Directional and Flat tops pistons, for some,........ a mystery.

2 stroke motor's reeds are just behind the carburators. But most boat motors are loop charged meaning the piston does the job of the reeds and fuel oil and air loops around the crank piston gos down and uncovers the intake port and fuel air charge is forced into the combustion chamber. piston gos up , next charge is loaded into the crank case, spark, bang! piston gos down and uncovers the exhaust port exhausts and more down uncovers the intake again and it starts all over.

the reed valves are located behind the carburator mounting plate

Valves are located in the heads, which are on top of the engine Block.

the reed valves you are refering to is actually the head gasket.

I think usually the carburetor.
