The odds of all the cylinders having the the same low compression are really slim and it may just be a problem with the gauge or test technique. Normally, as the engine wears, you'd expect the range between cylinders to increase.
Did you open the throttle for the test? A closed throttle would likely make all the cylinders read low, especially on a two stroke where you are counting on the air rushing in to spread the oil/fuel mix around and lube the rings.
I would spend the time and money to get it running then see how it works. If the compression is really low, it may be due to stuck rings and it might improve after you flog it a bit under load.
