Smelled Gas Leaks
Inspected/removed fuel lines and found signs of leak. Removed and inspected carburetor and found that seals and gaskets were toast. Replaced said seals with ones from the kit that fit and replaced fuel lines.

Would be nice to have a fuel line kit with the big fuel line (tank to carb) and the little one (carb to engine) together with all the necessary clamps.

The Spring-choke Return was not the right part.
The repair did not happen. The item number PS9294414 was the wrong
part. When I looked up the model number of 126-T02-0625-B1 engine after I tried to install it. The PartSelect answer was that they no longer had parts for 126-T02-0625-B1 engine any more. Do I need to send the
Spring-Choke Return and get my refund back. If so how do I do it.
