Someone just posted a video on Kijiji asking why the exhaust on his snowblower gets red hot & blows flames.  Any ideas? The problem shows up in the last few seconds of the video

Definitely getting gas in there somehow. Seems to run okay though.  I'd check the carb first.

Looks like the Carb was bouncing around, the mounting bolts are loose?

Might be shear pin / key or carb is out of adjustment. JM2CW.                                                                                        Roger

Go to youtube and search diesel generator first and last start. The guy seems to think there's a problem with it. I would post the link, but I haven't tried doing that yet.

On Youtube Videos all you have to do is post the URL and it will post your video :) (EG..in place of a comment just post https://www. youtube. com/watch?v=gwNfhEUqfuY without the spaces of course)

Muffler is held on by one bolt, air is being sucked in and burning the extra fuel from a not properly tuned carb that also looked a bit loose to me too.

I had the exact same thing happen to mine!! It fixed it self when it turned red hot and blew out the mouse nest in it. That muffler may have been defective internally that is why the engine wouldn't run smooth and was throwing flames. If he would have taken it off he would have seen the Genny run smoothly and handle a load.

On the original question, I would say the carb had to be turned up so much to compensate for the air sucking in that there is significant unburied fuel in the muffler. I wouldnt be surprised if he has the choke on.
Add to that the one bolt mounting method and the fact that it probably needs a ring and valve job from having the break in oil in there still... Well, you know...

It seems to run OK, missing 1 bolt in the muffler, exhaust leaks out there that's why it gets red with flames.

Looks like he shuts it off by closing the choke.

Lots of fuel, hot muffler, maybe some air getting the missing bolt hole = flames.
