timing a cat 22

Can anyone tell me the firing order of a cat 22? The serial #2f5868sp. Are there timing marks on the crank pulley or the flywheel behind the inspection plate? It has spark and compression and fuel😕there is a wico mag on it and a set screw is missing on the collar would that be enough to throw it out of time?🙄

thanks Doug
