QuestionI have a deere bc1600 with zama carb. It only runs in cold start position then in full throttle. It won't idle or start in normal throttle. I disassembled the carb. soaked and cleaned but had no improvement. Do you have any suggestions?
AnswerHello Joey:
>>Did you Check the Exhaust Port and Muffler?
>>If Either of these are Restricted with Carbon Deposits, then the Engine Either will Not Run or May Run at Idle but will Flood when you Try to Rev the Engine above Idle. The Following is a Basic Instruction File for Doing a Diagnostic on the Engine for this Problem. Any Input is Appreciated. **Remove the Muffler and Make Sure the Exhaust Port is Clear. If it is, then Try to Start the engine with the Muffler Off. If it Starts and Runs Properly, then Clean the Spark Arrestor Screen in the Muffler or Replace the Muffler if Required.
>>Have you Set the Carburetor Mixture Screws?
>>You can View a Breakdown/IPL of the Carburetor and Get Technical Information on Zama Carburetors at this Site Addy; http://www.zamacarb.com/tips.html and Select the Technical Guide.
>>Please, Do Not Hesitate, If you Hit a Snag, if I Missed Something or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.
Good Luck
