:confused2: Problems with lawn tractor fuel bowl acutator. Believed to be an electrical problem. For some time know I have had a off and on problem with the fuel bowl not filling with gas. Sometimes I could wiggle the red wire going to the bowl acutator to solve the problem. This must be a short in the wiring somewhere. I have un-taped the wiring back to the main harness and not found a short. I did note two red wires, with what appeared to be in-line fuse links, going into one red wire terminating at the acutator. I added a jumper wire before the two red wires ending just before the wire going into the acutator. Seems like the engine still wants to stall but a little choke resolves the issue. Could my "jumper wire" cause any problem and does anyone else have a better suggestion for a better fix?

Thanks gspald (new forum member) ****PLEASE HELP**** :confused2:

Contrary to what a lot of people think, The actuator as you call it is actually called an afterfire solenoid, and has absolutely nothing to do with filling the fuel bowl.. It's single purpose it to help prevent the bang after shutting off the key. On Kohler should be done at half to full throttle. The carb filling problem is either a fuel pump problem, and restriction in the fuel tank, fuel line, or something of that nature.


You can remove the solenoid, and clip the plunger off, replace the solenoid, or you possibly have a bad connection that is causing an intermittent problem.

Re: Cub Cadet 2166 with 16 hp Kohler engine / dies after start-up

:confused2: Still having problems with Cub 2166. Engine starts cold with choke but dies right after start. Have checked fuel system without locating any problem. Fuel pump working fine. Fuel lines all way from tank to carb inlet are clear. Begining to question Ignition Switch. Believe I have seen similar problems posted with bad Ignition Switches as the culprit. (May have even replaced mine several years ago. Old age, just can't remember for sure.) If indeed this could be my problem can anyone tell me how I could use a "jumper wire" to verify before buying a new switch?

Need model number

Re: Cub Cadet 2166 with 16 hp Kohler engine / DIES AFTER START

Mower is a 2166 model. I believe it is a 2002 or 03 model. The engine is a Kohler Command OHV 16hp, 426cc's, Model CH16S, Spec number 45509, Serial number 3209211461. I have checked fuel flow from tank to carburetor without any problem. Fuel pump works fine.

Mower will start briefly with full choke then die as soon as ignition switch is released. Problem is not with choke. Suspect ignition switch. Before replaceing switch can I jump between two wires on ignition switch without any harm. Wiring is as follows:


Yellow----> _ _ <---- Blue
Red------> _ _ <--- Red/white
Orange/Blk---> _


Green (ground) ---> ( _ )

I have chart that shows Red and Red/White wires should be RUN position. I plan to jump these two wires together.

Wow, I see a bunch of posts on the same mower, and they are all over the place!!! Stop starting new threads, and maybe we all can get together and help you.

Your engine has a funky ignition system, you might look there first.

Coil

Does your coil look like this?

I will get back with you on COIL. Will need to disassemble to reach coil.

Your 2166 Kohler has a SAM module on. It also has a diode in the harness. If you hold your key to start will your engine stay running??
I remember this because I lost 80% of my hearing in my left ear with this #&%! tractor. Not your problem, but it was a starting issue.

Response to your question:
Ignition Module (coil assembly) 12-584-14 02052 100600-2REV-30261 ASSEMBLED IN MEXICO
Digital Speed Advance Module 12-584-12 RE UC 62657

I have noted lots of surface rust on Ignition Module and Flywheel/Stator assembly. I plan to clean up the rust on these pieces and hope making a clean surface will allow the required amount of current. If this does not solve my no start condition would you tell me what checks I can do with my multimeter to test these two componants Note: I have tested ignition switch by borrowing another one identical to mine. Still no start.

Deerlane, You may have diagnosed my problem. I have noticed engine seems to continue running while switch is held in start position. Have been afraid to hold any length of time do to fear of damaging starter. Please give me more info. Sorry about your hearing loss! :confused2:

I had a similar problem with both my 2135 and 2165. Solution was to replace the OEM starter switch with a Cole-Hersee industrial quality switch.

:thumbsup: Thank you ALL for your help in finding a solution to my mowers sickness. The final repair was a bad electrical connection. Cannot believe two little wires and one bad connection could cause so much grief. :smile:

For future reference, to discriminate between a fuel problem or electrical problem try this. Most of these engines have a wire connection beside the engine that connects the magneto wire to all the safety shut down wires and switch kill wire. By disconnecting that wire, if the engine runs normal the problem isn't fuel related. Also if it now runs the problem isn't the mag / coil.

Glad to hear you found your problem.
