I can't get gas to come throw the caborator. Is there something i can adjust? I have a murray ultra 17 hr. with an enduro xl/c tecumseh.i can't see any thing on it to adjust.if i hold my hand over it then it will get some gas and run but not good.

Sounds like your Carburetor is clogged. Some times you can take a spray Carburetor cleaner & spray it in & that might clean the jets... if not you'll have to disassemble it soak & clean.

Remove The Float Bowl, Using The Tube On A Can Of Carb Cleaner, Spay Up Into The Jets, Spray All Around The Float, Clean The Bowl, Change The Fuel In Your Tank, Clean Out Tank With Carb Cleaner, Capture Carb Cleaner In Container To Properly Dispose Of Old Fuel, Replace Fuel Filter , And Add Fresh Fuel. Try Again.
If You Still Have A Problem. Carry Carb To Shop Or Clean Really Well Yourself.
If This Still Doesn't Do It, Purchase A Carb.
And Not Being Mean , But Next Time I Wouldn't Buy A Tecumseh. They Are Notorious For Carb Problems.
