2000 Chev Blazer Sticking - Fuel System

Question: Pedal sticks only on initial acceleration. Checked link, ok, Was told that this is because oc carbon build up on the carburator butterfly, which I verified and wiped with a cloth to remove some of the sticking, but not all. What is the best way to clean this crbon off the carburator? Thanks pjb

Technican: Hello, You can do this: You'll need a spray can of choke cleaner, a small acid core brush or equivalant, some rags and a cool temp light such as a flashlight or floresent drop light. In a well ventalated area, remove the air inlet duct as needed to access the throttle valve and bore. With the key 'OFF', prop the throttle wide open so you can get to the coking built up on the valve and throttle bore. Use your light to inspect where the valve and bore touch when the throttle is closed. Wear eye protectiuon and spray the identified area to wash loose the coking. Scrub the bore and valve as needed with your brush and wipe what you can reach with the rag to get the junk out of there. Spray the rag itself and wipe the valve and bore 'til you like what you see and its' as clean as possible. Close the throttle and operate by hand to check your work. Works smoothly without sticking?? You're done. Reassemble and prepare to start the engine. Clear the area of spectators as exhaust fumes will be heavy and smokey on start-up. Not a good idea for children to be around. Press the accelerator about 1/3rd down and crank the engine 'til it starts. It will be stubborn at first due to an overly rich air/fuel mixture. Once the engine clears this excess chemical out, you're road ready. The $150 at the dealer often includes flushing the fuel injectors too. You may find a fuel addative to put in your fuel tank to be adequate to keep things humming. Does it run good? Throttle smooth to come off idle? Done!!

Technican: Hello, Have you tried to clean the throttle bore with this method I've suggested? Please advise.
