could be a number of things, a leak down test would be nice for a direction

 

Ok, I took the air hose and blew some air into the spark plug hole, and it was coming out the exhaust. I was messing with it a bit and after a minute or so it stopped letting air out the exhaust. I did a compression test on it again and the cyl that had zero now has 120 psi. I guess there could of been a chunk of carbon or something that fell down and wasent letting the valve seat all the way? Does that sound possible to you guys?

 

thats definitly good that you have compression back, its possible. what did you do from the time air was coming out the exhaust from the time you did the compression test, what changed? does the engine run?

 

It is possible. Something was keeping the valve from closing.

 

Once the air stopped coming out the exhaust, I put the plug back in and started it for a second, it ran good, so I did the compression test. I've let it warm up completly and i drove it around, turned it off, let it cool, then started it again. It's all working good so far

 

thats good, you must of had something hanging up in there
