Finally finished working on my fourwheeler today, now im not getting Compression, and all the air is coming out of the carburetor. Could this be the valve not sealing correctly or anyone have any ideas?

Sounds like your intake valve is opening on the compression stroke?

What kind of work were ya doing?

There are two times when an engine is at TDC are you getting air blown out the carb EVERY time the piston hits TDC or every other time?

Pull your valve covers and see if you have a valve stuck open on either stroke or maybe you didn’t adjust valves correctly.
