Certainly the carbs should be treated as a pair and so when one is suspected both should be checked. The cylinders will be unable to perform equally unless both carbs are tuned equally and synchronised at idle and at various throttle openings.
As part of the checking process it is important to ensure both cylinders are capable of performing equally. A compression test has limited use and a cylinder efficiency test is better. Injecting compressed air into the cylinder would prove the effectiveness of the valve seats and piston rings. A small amount of leakage of the inlet valve seat would make little difference to a compression test but it would make a great deal of difference to the way the cylinder performs.
Another important check is the valve clearances and also the ignition timing if it is adjustable. Some engines with twin ignition systems need to have the timing set for each cylinder.
