Yesterday I was syncing the carbs and every so often there's a little pop of air coming back through the sync port...maybe every 10 seconds or so, otherwise there's a vacuum there. The little pop is strong enough though, that it will blow the sync hose off the port after around 5 or 6 pops.
I also noticed when I was changing plugs that there looked like there was air blowing past the spark plug but it was barely finger tight so I figured it might be that.
Compression on the cylinder was 165, and held that for around 5 minutes before I removed the tester to check the other cylinders, and the other cylinders were in the 160 to 170 range.
I'm not sure if I'm losing antifreeze yet, as I haven't noticed the overflow tank losing antifreeze.
If the rain quits I can get a short video of it by hooking up the synchronizer and you can see when it happens as it pushes the rod down.
What are your guys thoughts? Thanks in advance for any help.
