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.
