Small Engines (Lawn Mowers, etc.): Homelite UT08111A leaf blower (Backpacker) SURGING, carburetor body, backpack leaf blower

Question
My backpack leaf blower surges after about 3 mins of use
I have tried to make adj. with no luck.
I have check carb mounting screws and all tight
what I have found out and there seems to be alot of bubbles comming up in the fuel tank.
sometimes I can take blower off my back and hold it sideways and will blow good for a while.the other way to make it better is if I pinch off the return line going to the fuel tank it will run good.
I have read other post but im asking mabe someone has had this happen

thanks in advance Robbie


Answer
Hello Robbie:

From your Description, it Sounds like the Carburetor Needs to be Soaked and Rebuilt. Is the Exhaust Port and Muffler Clear of Carbon? If Yes, then I Suggest you Replace the In Tank Filter.  Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I Use Gunk). I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning. You Only have to Remove the Bowl, Float Pin, Float (if Applicable)  and Needle Valve and Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed. Then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts. Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. I Require the OEM (Walbro, Zama, ect) and the Model Numbers Off the Carburetor. With these I can Locate a Breakdown of the Carburetor and Better Assist you. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
