ANSWER: Hello Bob:
Spray Carburetor Cleaners are a Waste of Money on Small Engine Carburetors. Unlike Auto Engines that are Used Daily, a Mower is Used Weekly or Bi-Monthly. The Varnish is Harder to Remove. It has had the Time to Harden in Layers. Here is the Only Way to Really Clean the Carburetor. 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 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. You can View a Breakdown/IPL of the Mower/Engine at this Site Addy, http://hayward.arinet.com/scripts/EmpartISAPI.dll?MF&app=ASP&lang=EN&TF=Mainfram and Select the Catalog American Honda. 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. Thanks.
Good Luck

QUESTION: John:
Tried as you suggested ,disassembled carburetor,soaked overnite in gunk carb cleaner,blew out and reassembled,same trouble as before.Engine starts right up but continually surges with choke open,when choke 3/4 closed seems to idle fine. Engine does seem to smooth out somewhat when a load (log splitting) is applied: however, it resumes surging when load removed. I will say I'm getting real good at removing and reinstalling carb:)What would you recommend next,replacing the carb. perhaps? I found one listed for $28.95 on a link from your web site,this one being listed as for a GCV160 engine.Mine is a type N5AF with a manual choke/fixed throttle,hopefully this would be the correct carb.Any suggestions would be appreciated as its getting mighty cold in this part of the country and I've got a lot of wood to split.
Thanks
Bob
AnswerHi Bob:
If you are Sure there are No Leaking Intake Gaskets, then you May have to Resoak the Carburetor or Replace the Carburetor. I have Soaked Many Carburetors More than Once Just to get them Clean. It is Not Unusal to Soak a Carburetor as Many as 3 Times Before it is Properly Cleaned. There are 4 Carburetors Listed for this Engine. 1- 16100-ZM0-803, (BB62B D) (Honda Code 6212849). Use up to Engine SN 2225727. 2- 16100-ZM0-804, BB62B E) (Honda Code 7862345). Use up to Engine SN 2225727. 3- 16100-Z0L-811, (BB62H A) (Honda Code 7555147). Use from Engine SN 2225728 to 3036309. 4- 16100-Z0L-812, (BB62H B) (Honda Code 7866072). Use from Engine SN 3036310.
