:lol: You can vent that rubber tube from the motor out onto the ground that is dumping oil into your filter. You just have to plug the hole up where the hose went into the carb area so it doesn't suck in dirt..

Yeah those carbs are nothing but trouble.. It might be a lot easier to just get us a pic of your carb. If it's the correct carb for the motor theres a good chance there is no spring because the carb just uses a one speed jet that screws into the crab tight.. If it is running an older carb with fully adjustable settings it would have a spring.. But either way, just finding that screw for your carb should not be hard.. a LOT of them get replaced with better carbs and people have them laying around.

Go to "Race City Race Parts" on line. I ordered my replacment carb screws from them and had them in 3 days. Tip: Dont be cheap and order extras just in case, they're only two bucks a pop and come with the spring.

Tecumseh carb kit #31840 has the needle and oring you need. The spring/washer holds the oring tight for a good seal. Try a mower shop for parts, too.
