ebinmaine 72,740 #2 Posted January 23, 2019 If the muffler is red it's likely too lean Share this post Link to post Share on other sites
Larry Chamberlain 22 #3 Posted January 23, 2019 Now what screw do I adjust this with or should I just take it to a small engine guy and have him do it Share this post Link to post Share on other sites
ebinmaine 72,740 #4 Posted January 23, 2019 You can do it yourself if you take a look at the Kohler manual or search here on the site for the directions. I think I'd start with Both screws about 1.5 turns out but I don't know for sure on your engine. Share this post Link to post Share on other sites

Howie 899 #6 Posted January 23, 2019 Initial settings on that carb is, 2 1/2 turns out on idle screw and 2 turns out on the high speed screw. High speed screw on top of carb, idle screw on side at an angle. Check point setting also. 3 Share this post Link to post Share on other sites

953 nut 60,086 #8 Posted January 23, 2019 @Mikey the Monkey has provided the proper information on carb settings. If your engine has a battery ignition system with points they may also need attention, the points setting will also set your ignition timing. If tuning the carb does not clear the problem up let us know and we will fill you in on the points procedure. 2 Share this post Link to post Share on other sites

pacer 3,177 #12 Posted January 23, 2019 Should also be pointed out that its not that unusual at higher rpms for the exhaust pipe to glow red at/near the outlet --- and occasionally to spit sparks out. Would imagine you guys using your snow plows/throwers at night running at high throttle can attest to that. 1 Share this post Link to post Share on other sites
rjg854 12,216 #13 Posted January 23, 2019 Funny that you mention that, I just happened to notice my stack glowing red this morning before sunrise. Share this post Link to post Share on other sites
Larry Chamberlain 22 #14 Posted January 24, 2019 I believe I cleared it up did the 2 1/2 to 2 and seems to be running pretty good it has a very dim glow in the exhaust once in a while will see a blue burst in the pepper can runs very smooth no missing at all Share this post Link to post Share on other sites
