Cub Cadet 1862 spark plugs
 

Hello, newbie here from Norther Illinois. Hoping this is the proper way to start a new thread, anyways I'm working on a 1862 with an 18 horse Magnum that I picked up while cruising the countryside. Found on side of road with free sign. Has weak spark and noticed it had 2 different plugs. RS14YC and on other side Autolite 26. Both were gapped @ .045 Online manual says Spark plug #759-3334 and should be gapped at .025. I tried cross referencing the Cub part number and I've gotten 3 different plugs. Can somone point me to the right direction. Thanks

For what worth...

Welcome to OCC,
in out technical section you can down load the service manual FREE.
It should answer most of your questions.
(RV17YC @ .035)

After my reply I see the discrepancy you saw.
My info is from the Kohler service manual.
For what it's worth, experience says both gaps/plugs will work fine.:beer2:

I thought it took RC plugs.... but I was going off memory.

I gap mine to .035" and run it. +/-.005" won't make much difference.

If it has weak spark, it likely needs a new magneto. (Ignition "module" according to the parts book.)

Service bulletin #265

Glad you found that service bulletin and thanks for all replies. Now I can move forward on this. Now I need to be sure that incorrect plug that was on one side did any damage (RS14YC, threadreach is 6.3 mm longer than oem plug) Most likely will need ignition module (weak spark). I tried downloading the service manual in the technical section, there is none for the 1862.

You need the engine sevice manual. It's in the tech section. The chassis manual doesn't cover the engine.

The 1862 had a Kohler M-18 in it. In the Tech Library Section, is the M-18 Service Manual.

Please bear with me, where is the tech library section? You mean the Cub Cadet parts and service look up? Top of page? Thanks
