TKS system ~ Rough idle

[alldodge]

Turning the key off and the motor continues to run is called dieseling, and that's hard on the motor. When this happens you need to turn the motor back on and then off again. Dieseling is caused by idle set to high (which it is), carbon built up in combustion chamber, incorrect timing, throttle cable not adjust correctly.

Stating your idle is not correct and fluctuates, check to see if you throttle cable is not dragging and is adjusted correctly. Remove the throttle cable off the carb, carb should be fully against idle stop screw. Start motor to see if it idles correctly (engine warm). Increase the idle a tad a couple times and see if it returns to idle. If this is all god, then the carb is not binding.

Now adjust the throttle cable so it just slides in the carb post. Now remove the cable again and turn the barrel one more turn further closed. You want a slight bit of tension pushing the carb closed when you shifter is at idle

HI Guys

does it apply this issue for mercruiser 3.0l 2009 TKS carburetor?
I checked the TKS module with ohm meter and I measured something there but did not check with voltage.
I m happy for you Alexvelarde , finally I see somebody fixing this annoying issue.
Unfortunately it s hard to find good mechanics where I leave so maybe you guys can help me. My boat was serviced by 2 different mechanics and one of them gave up , the other one said it s fixed and actually wasnt.
The symptom is : starts pretty good when cold (IDLING ROUGH BUT IDLING ) running like champ when in speed, after that very rough idle( and stall) . If I try to start it when warm I cannot ( if I use the throttle 1/2 it starts right away).
I checked the electric plugs , distribution etc , the fuel line , carb , jets and the gas.etc.Nothing.
Now guys I saw this TKS topic and I was thinking maybe here is the issue.
It s idling rough most of the time , sometimes for few minutes maybe ok but it s bad in general.\
any advise will be very appreciated

Thanks in advance
Cheers

Throw the TKS in the garbage! Replace it with tried and true electric choke.
