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?

Have you tried just pumping the primer periodically once it starts to keep it
running a few minutes? Sometimes the fresh fuel flow will clear the clog.
