QuestionCub Cadet 1650 Tractor w/ K341 18hp Engine
My Cub Cadet starts and idles fine, but quits for no known reason, usually
when increased and maintained. Has worked fine over the past 5 or 6 years,
and for long periods, then suddenly quit a few days ago, and has not worked
properly since. I removed and cleaned out the gas tank (quite a bit of debris
in it), removed the carb and cleaned as well as I could, removed the jets and
cleaned, readjusted the carb, put in new spark plug, reset and adjusted
everything and it seemed to fix the problem temporarily. I started to use it
yesterday, and it just quit again. It will restart but only idle or run with small
throttle increase. Am unable to adjust points, as frame is in the way to
remove the cover. Don't know what to do. Any suggestions? Jim
Answer Hello Jim:
Did you Soak the Carburetor Overnight in Carburetor Cleaner and then Blow out the Passages with Compressed Air? If No, then Reclean the Carburetor. Here are the Instructions for Setting the Air Mixture Screws. **The High Air Mixture Screw is In the Carburetor Bowl in the Center of the Nut or Some Carburetors have Both the Low and High Side by Side on the Top Side of the Carburetor. The Screw Closest to the Engine Is Usually the High Air Mixture Screw on this Type Carburetor.The Low Air Mixture is the One at Top on the Side and Goes Into the Carburetor. Some have the Idle Air Mixture Screw Going Vertically Into the Top of the Carburetor. The Idle Screw is the One that Moves the Throttle Plate. The Following is the Directions for Setting these Screws. **If the Carburetor was Soaked Overnight in Carburetor Cleaning Solution and the Passages Blown Out with Compressed Air and a New Kit Installed, then we can Set the Air Mixture Screws. Turn Both Air Mixture Screws In Until Seated. **DO NOT JAM SNUG ONLY** Turn Both Screws Out 1 1/2 Turns. Set the Throttle to Full Open and Start the Engine. Override the Throttle by Pushing the Governor Arm by Hand and Turn the High Air Mixture Screw(bottom of the bowl) In Until the Engine is Revving Properly. Now Slow Engine to Idle. Set the Low Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Now Set the Idle if Required.** Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.
Good Luck
