Combustion/cylinder temp goes way up when leaned out = hot exhaust. It could very well be the ingition timing is off due to a buggered key, just seems unlikely being only a 5hp in generator service. The only way to really *jar* the output shaft and/or flywheel & distort the key would be a massive backfire. If it was running rich it would be puffing black smoke and running like p00p.

So.............how is running lean going to create excess heat in the exhaust?

Aircraft give you the ability to adjust the fuel trim (A/F Ratio) while in flight. Leaning things out will increase fuel economy, but increase the EGT (Exhaust Gas Temperatures). If not kept in check, the engine will begin to overheat and could possibly fail, which is not a good thing while flying.

I'm not here to tell you why, but I am here to tell you with ABSOLUTE CERTAINTY that running lean increases the temperature of your exhaust. I'm sure the 7 people in this thread that said to check the carb because of a possible lean condition aren't total insane.

It's the new normal. Many new small engines do this. My Honda 13HP pressure washer does it, my old Briggs 6.5HP pressure washer does it. Most new 4 stroke dirt bikes also get the pipe red hot.

That's true. A co-worker of mine reported his single cyl Vanguard powered gen's muffler glows red near the outlet, only noticeable in the dark when it's been running loaded for a long time.

Thanks for all the advice. I will tear into it this weekend. Iím treating this as a learning experience.
It needs normal maintenance so Iíll change the oil, air filter, and spark plug. It has old gas in it which Iíll drain and I will clean the carburetor and play with the mixture. I will also check the flywheel.
Boy this thing is loud. Iím also going to trying to get a bigger muffler for it.
It surprised me by starting and running. Usually when something like this happens, I cannot get the ##@ thing started.
