WC Sticky valves ????

We just started our WC for the first time in years. As it starts it seems to fire OK but then just contunues on one cylinder.
Has very little power and when we try to run the speed of the engine up it snorts and backfires.
It seems to me like we've got some valves that aren't closing. ?????
Can these be freed up without pulling the head and doing a valve job???
Would spraying with liquid wrench from the top spring area help this????
 
Remove the valve cover and watch it while running. You might have a broken spring or two. You can see what kind of lubrication the valves are getting. You should see oil running down each valve stem. "You can observe a lot by watching." Yogi Berra.
 
Sometimes! If you haven't yet you need to check the push rods to see if they are bent. A stuck valve can and will bend a push rod.

If a or some valves stuck and someone has decided to do this below it would be hard to get lube down in the guide without removing the spring.

One like that can have many problems. Before I ever start one like that I put ATF in all the cylinders nd let it sit at least a few hours. That cleans up rust and loosen the rings. Does not do much for the valves but will if enough of it get into the oil. I would do 2 things at this point. #1 put some ATF in the cylinders, can not hurt a thing but may help a lot. #2 pull the valve cover and make sure you do not have sticking valves and or bent push rods etc.
