So I have a 1976 Montgomery Ward Transaxle 8 that I have been working on. I have cleaned the head, replaced the crankcase breather, Rebuilt carb, Cleaned valve faces to shiny, replaced spark plug, and replaced the mufflerDSCF5540.JPG DSCF5543.JPG . When it runs at full throttle, it doesnt take long for the muffler to start glowing. I dont feel that this is normal and was wondering what might be the cause of it. I ran some seafoam in it in the beginning and was wondering if that might be the cause. I also run high octane gas in all my equipment and was wondering if that might cause that too? Also wondering if anyone has a battery cover that goes on this as mine is missing. as seen in last pic.DSCF5536.JPG

I can tell that I used to light my cigarettes off of our Gas powered farm tractors, and their mufflers glow red all the time when working them. Lawn/garden tractors burn up every year from combustibles catching fire in the engine area.

Sometimes a tractor that is running lean will run hotter. Maybe open up the main jet a quarter turn and see?

My BMW R65's exhaust pipes would glow red clear to the muffler as well.

These things do run hot. However, if the timing is advancd too far, it will heat up a muffler far faster than normal. I didn't see timing mentioned in your post, have you checked it? When I first got my JD140, I accidentally set the timing about 15 degrees too advanced, and I could have welded that muffler with itself!

Ditto on the timing.  I had a Tecumseh that was turning the muffler red.  Sounded like it was running good too, but lacked power.  Finally tracked it down to an ignition timing issue.

i actually did nothing to the "timing" as it fired off when I cranked it. I believe it might have a magnetron, but I dont know for sure. Should I check flywheel key, points and condenser, if so equipped!  I did put an E3 plug in it.But it glowed when it had the old plug too. there is just not much to check on a briggs when It comes to timing. Someone please explain

it has a mag, but has the smaller starter bolted to the side of the engine with an alternator under the flywheel

If it's mag-fired, then usually the only way for timing to be off is a sheared flywheel key. The gap between the flywheel and mag is part of it, but you usually can't screw that up too much and still have the engine fire.

I used to have one of those cheapo jd l140s and was mowing one night and and on both cylinders the pipe was glowing.  But as far as glowing pipes my kawi 450 with titanium header pipe hill glow read clear to the muffler

Try adjusting the high speed jet 1/4 turn richer and see if it changes anything. Too lean maybe?

Was it a repower? 140's have 1-cylinder Kohlers.
