hi
I have a Tecumseh TVS90 lawn mower. It starts fine but now shuts
off
immediately.

I took the gas tank off and cleaned it out - wasn't much debris in
it
and the screen was clear.
Tried to check the bulb for a pinhole leak by covering it with duct
tape - did not make a difference.

I can't get to the rest of the gas line b/c the air cleaner mount
screws (which blocks access to the gas line) are stripped.

Any thoughts?

Most likely a gummed up carburetor. Gum Out or some such product may
help, but most likely it'll take removing the carb for a cleaning.
