Glowing red muffler..

apparently the 15 hp Kohler doesn't like to saw 15x21x16' cants down to the deck without pausing to off bear...it was getting dark and I just wanted to finish the log...sawed it right down to the deck..or at least 10" of it....muffler was glowing...guess maybe it's running a bit lean...I'll pull the plug in the daylight and check it..sure would like on of those big Cats.. ;D

Zopi, Were you sawing those nice pine logs you scored on or were you sawing something harder.

I think you'll find that pretty normal in the small engine world. We have Hondas, Briggs/Strattons and Kohlers that all will do the same thing when operated at capacity. My favorite is the Briggs on the Forest Fire Truck in Town. That whole muffler glows red after dark, no lights necessary.

You will notice that a lot on small engines when running them nocturnally. ;) We used to blow leaves in the dark sometimes trying to finish up a job and not have to come back. It was amazing how the mufflers would glow, and the amount of sparks coming out of the engines. Amazing that we never set any leaf piles on fire.

It's amazing the sparks coming off of the bandmill blade on an opening cut at dusk too ;)

hmm...y'know, thinking about it, the mill is the only thing i have that gets run at full throttle at all..maybe that's why i never noticed it..

Yeah, and sawing dry cypress is a monumental task for blade and engine alike. Believe it or not, dry cypress sapwood is hard to saw.

8) 8) sparks fly upward leaves are on ground :D :D

Heey Guys just read your discussion On why you Mufflers glow red hot as you wouldve read the name My name is sam and I work for vermeer Australia we have the same problem over hear with contracters trying to cut or grind a stump for example That is bigger than what the horse power the Engine iis putting out From my experience I have a lucas Mill and I had a 15 hp kohler and Had to upgrade to the Kohler comannd 30 hp This is just from my experience I found when the muffler got to hot the engine would overheat and was really hard too start again.

thanks guys

We've got two portable 500gpm pumps on our fire trucks here in town, they have 6-cyl compact Nissan gas engines, and when they get running hard, even in daylight, they get bright cherry red.

Most engines will glow when under stress. I wear a blue T-shirt most of the time, but you would never know it, because, when I'm thinking real hard, it turns red. :-\

logwalker · March 15, 2008, 12:52:43 AM

Tom, that is funny...I thought it was when you told a little fib it would begin to glow. I am glad you straightened me out on the misconception. :D :D

Dave Shepard · March 15, 2008, 01:00:07 AM

My Super M used to glow pretty good when I shoveled the oats in the hammermill, it did a good job, but about 60 horse shy of keeping up with what the hammermill could take. That's what the 1256 is for. ;)
