Time for New Carb ?

Donsyl · Jul 23, 2011

Hey GTSRider i have a 1811 cub and it has a spring loaded screw near top of carb and when i pulled it out and sprayed carb cleaner in there it started running better. I didnt take that out the first few times that i cleaned the carb i dont know why but anyways it seemed to help a lot. I have mowed twice now with no troubles. good luck Don

Will keep you posted.

Ok...latest update on my haunted. possessed 3000 series Cub Cadet.
After 4 months of needing choke to run 1/3rd way up.... today started
her, and engine ran perfect for 2 solid hrs. of mowing with no choke needed !
Bad news.... it now idles oddly, and visably smokes at idle....
What would be causing this engine to smoke at idle.... and it will run on...
this after I just put in new Kohler fuel shut off solenoid....
if I had the $.... I'd buy something new... but the power steering , and lift is a nice feature.

might be as simple as adjusting the carb. there is both a high speed and idle jets generally on the carb. owner's manual should show proper adjustment procedures.

GTSRider Just went thru the same deal on my precious 3225. My dealer told me the problem was not the fuel shut-off but the 2 o rings#16 on the #17slow jet on the CC parts. That did stop having the choke at 1/3 closed but It still runs rough,pops a little but after opening the throttle and blade engaged it runs fine. I really have my doubts that contiued running having to choke it if its good for the engine. By the way i just read that Kholer is going EFI on new engines now!!!

Hey...thanks for the response...I KNOW you hit on my problem..because ,
I recently was having problems trying to replace them and damaged one.
Can you elaborate on #16-17 please ?
Where can I get these ?

For anyone else with this problem....the O-ring # are 24-153-02-S.
These are the 2 O-rings on the idle jet for the Kehein carb on the
Kohler V-twin. The list for under $3 for the 2....expensive... but when you need them... you need them.

If that is a Kohler 20, maybe this will help.

Pay attention to the low speed jet setting.

I believe the high speed jet is fixed.
