If your TTR-50 only runs with the choke on, it likely indicates a fuel delivery issue, such as a clogged fuel filter, dirty carburetor, or a blockage in the fuel line. The choke enriches the fuel mixture, compensating for insufficient fuel reaching the engine. This condition could also point to an air leak or a problem with the carburetor's adjustment. It's advisable to clean the carburetor and check the fuel system to resolve the issue.
Your Briggs and Stratton 5.5hp only runs with the choke on because it needs a tune up.

You might check your primer bulb. Mine was cracked and the only way it would run was with the choke on about half way. I changed the primer bulb -- problem solved. Hope this helps.
You have a plugged piolet jet. The carbs need to be gone through
Standard is full choke first, then half-choke for a couple of minutes, then run.
Obviously a weak mixture, as using the choke makes the mixture richer. Quite possibly there's an air leak between the carburettor and manifold
yes you can choke on feathers but only sometimes
MY lawn mower will start to sputter if I run the choke on after the motor is warmed up. It's getting fed too much fuel. Ease off on the choke and it will run better, usually.
there should be a dip stick on the bottom of your filler plug.
Until the engine will run without the choke being pulled.
If it runs with the choke on, Then it will not do any good to adjust them. It is running lean/ not getting fuel. The carburetors have dirt in the fuel jets and that is why it won't run when choke is off. When choke is on that richins the fuel up and it try's to run. Need to clean the carbs out.
