The duckbill valve in the cap is NOT intended to keep the fuel tank from 'pressurizing'. It's a one-way valve to let air IN as fuel is drawn out while retaining fuel and pressure. There is almost always pressure in the tank, especially once the fuel warms up and vibrations 'shake it up'. As the other guys said, these saws will boil the fuel when they get hot. Clean the cylinder fins. Clean out the underside of the flywheel cover. BTW..............pressure in the tank will RAISE the boiling temp of the fuel. Lower pressure (like when you remove the cap) will lower the boiling temperature. That's why hot saws will suddenly boil the fuel when you remove the cap. Think of the radiator cap on your car....
I can only imagine the rush of cutting something that big. Holly crap. I've cut some big tulips out here on the east cost, and they got the knees to bobbin. You gotta cut the saw of and listen to it fall. WOW!

I saw a tree almost that big when I was in Evansville last week, right in town! No way would I attempt to cut that one down..
New dedicated saw workbench I have been working on.

How dare he show us something like this!
Figured out where the reed valves were and checked them out. Seem good. Same problem. Can get a couple pops out of it then nothing. Very wet in the cylinder. Could gas be leaking through into the cylinder from somewhere. As well I'm going to pull the flywheel and make sure the key way Hansent sheared. Could be a timing problem.
Still scratching my head.
Ok I soaked it in acetone and put a new carb kit in and it's still flooding like crazy. Looks to be a issue with the carb itself to me. Unless the lever is set wrong. Needle not seating? A port still plugged? Damage to the carb? After I put the kit in dry it fire and ran for a couple secs till it flooded again.
Any ideas?
If any of you have seen mine I hope you forgot what it looks like...
Bet he's even got heat and A.C. in his shop.

When I was waiting for parts to come for the Titans, I worked
on this saw. I got this saw a few weeks ago. It looked like a pig pen.
I was going to repaint the whole thing, but after cleaning it up it did not look to bad.
I just painted the the top cover and rear handle and put decals on it.
Metering lever height set wrong.................or possibly you have the metering chamber gasket and diaphragm order wrong. Gasket should go on first, followed by the diaphragm. Other possiblility is that the needle isn't seating right with the seat (either grit holding it open, or the seat is damaged). With the carb all assembled, put a piece of fuel line on the inlet barb and presurize it with your mouth (or with a low pressure pump and about 5 pounds of air). Should hold. Is your carb a Walbro or a Zama (can't remember if you stated..........and that saw could have either)...
