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?
thx
bob
