Spark plug replacement on Craftsman Lawn Tractor

Someone kindly sent me to the spark plug replacement site to check out a replacement for a TorchF6RTC plug.

The suggested replacement seemed to be Champ. RN11YC.

I ordered that from Kohler (thru Home Depot) and they sent me Champ. RC12YC.

Will that work?

Thanks,

JD

Yes it should work not a problem.

The RN11YC crosses onto an NGK BPR5ES which is the about the same plug as the champion RC12YC.

Here's a site to cross Spark plug cross reference

The Touch F6RTC crosses to the NGK-BPR6ES according to the site

According to the site the NGK BPR5ES crosses to a champ RN12YC4

According to this site there is no cross to a champion.

Oh, Boy...two replies...two opinions.

Maybe I should ask if the RC12 would do any damage to the mower?

The rc12 will not foul out if you run a little rich

(( racing is the only sport that you need two balls ))

As far as damage to the mower I couldn't really say but seeing how the F6RTC doesn't cross to a champion according to the site I personally wouldn't be using it in my engine. I mean why would you take a chance when you can go to some place like Auto Zone and get the NGK- BPR6ES which is the direct replacement and have the correct plug, personally IMO a better plug than a Champion.

What engine is fitted so that you can get the right plug fitted?

If the spark plug came in the engine from the factory wouldn't you think the F6RTC would be the right plug?

Iv never heard of this plug or seen it used in any engine manufacturer.

I only go by what manufacturer recommends.
Iv never understood this thing of NGK are better than Champions but Champions better than Denso
etc etc.

Briggs use champion, Honda Denso or NGK, Kohler use Champions, Kawasaki use NGK and Tecumseh use Champion and NGK.

Imo a plugs a plug just different heat range and lengths etc.

If its a Kohler engine as the op bought from Kohler the RC12YC will be the correct plug.

The tv show hot rod tv did a test all they changed in the engine was the plugs out of 10 plugs the only one that had a HP gain was acdelco

Did same test with oil and every oil had deferent HP

Torch is I believe a Sears thing. I think you'll find they use them in the Craftsmen Model engines from Briggs and Stratton. That's the reason I picked the site I gave him, it's the Sears Site. According to them the only cross for that particular plug are the ones I gave earlier.

If I were him I'd make a trip to the nearest Auto Zone and buy the NGK, He'll have the right plug for the motor and he won't have any problems.

Use an RC12YC and you will have no problem. Kohler has been running that plug for years. This is not the first time I've seen Sears switch out plugs which make no sense to the mechanic or customer.

The R12yc is what's in my Kohler, now, but it's not the same as the one that came originally. It seems that no matter what engine I change original plugs in, I find out that that particular plug has been superceded by a new one. I've gotten to where I buy them in quantity so that I don't have to stare at the shelves of plugs like a complete idiot.
