Small Engines (Lawn Mowers, etc.): kohler command 22hp, carburetor body, country clipper

Question
Help I have a country clipper mower i just bought 3 days ago it had been sitting for 2 yrs I got it to run and tired to mow with it and it would start running rough and I would have to run withe the chock on so I bought a new vac. fuel pump ,new voltage reg, new key switch thinking it would be one of the above parts I also replace all of the fuel lines new filter also and drained fuel tank two time  and blowed it out then i took off carb and cleaned out and didn't see anthing really bad. after all of this I tired to mow it ran really good  for about 4 to 6 min. then it started to lose power and try to die I would have to put the choke on just to keep it moving enough to get to the shop it seams that if you let it sit for a few min. and start it back up it will run fine for a few min. then start running bad all over. also I replaced the battery  too. p.s this is a 60 inch zero turn commerical duty mower

Answer
Hello Matt:

From your Description and If this Unit has Set for 2 Years and Not Been Started, then I Suggest you 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 Accidential Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. Send me the Model Numbers Off the Mower and Engine, Please. With these I can Locate the Proper Manual and Better Assist you. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
