Answer
Hello Jose:

Send me the Model Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Does the Carburetor have Air Mixture Screws? They May be Out of Adjustment. You are Saying Throttle. Do you Mean the Choke Out it Runs, but when the Choke is Pushed in it Quits? If Yes, then Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I use Gunk). Then Blow Out the Passages with Compressed Air. Install a New Kit if Required. I Know this will be the 2nd Cleaning, but it May take 3 or 4 Cleanings. This is Not Unusuall for Carburetor Cleaning. Hope this Helps. I am Here if You Require More Assistance. Let Me Know What Happens, Please. Thanks.

Good Luck
