psalms83:18 174 #3 Posted December 12, 2015 same for c-160 for a c175 right?? Share this post Link to post Share on other sites
pfrederi 17,771 #4 Posted December 12, 2015 C175 would use RBL15Y ( if you prefer, as I do, plugs that actually work use Autolite #25) .025 plug gap Points are set at .017 Share this post Link to post Share on other sites

I did check both my c160 and the b80 and they had h10c in both.i have been doing a lot of research and others like the autolite 216 for the k341. and autolite 458 for the k181.what do others think about this.

roadapples 6,983 #6 Posted December 14, 2015 (edited) H10C or 216 for the k341 is correct. Not sure about the k181. You don`t really want resister plugs. Points, 4715003-s Edited December 14, 2015 by roadapples Share this post Link to post Share on other sites
Mike'sHorseBarn 3,002 #7 Posted December 14, 2015 I use J-8C in all my k181"s and H10C in all my 10-14 hp kohler's. Not sure about the 16hp though. Share this post Link to post Share on other sites

Mike'sHorseBarn 3,002 #11 Posted August 1 Hmm I've never seen the different gaps for different ignition types before. I've always set my plug gaps at .025. Share this post Link to post Share on other sites

sqrlgtr 552 #13 Posted August 1 I'm running NGK B-6L in the k341 and NGK b-4 in the k181's but have had good luck out of the Autolites also. I started running the NGK's in old VW bugs and thought I would try them in the Kohlers and never looked back. I would prefer either of these over the Champion's, but everybody has their favorites. I got a hold of some bad Champions way back and that's what soured me on them but lots and I mean lots of people swear by them... .025 on the K181 and .035 on the K341 and .020 on the points but that may vary only your engine knows where it will run the best. .020 will get you close enough and may work great for you. 1 Share this post Link to post Share on other sites
