The reason the muffler is glowing red is because the exhaust temperature is off the chart.
This (highly likely) means that the ignition timing is out, or the fuel mixture is too lean. One possibility on small engines that run a flywheel magneto is that the keyway/key may have damaged itself or sheared off, allowing the timing to go out. Or, the carburetor is gummed up, not allowing full flow of fuel.
What does this mean? Well aside from the engine going outside of it's safe operating temperature (wearing out components faster), it can also lead to detonation, which is where the fuel is igniting before the end of the compression stroke. This can result in breaking the connecting rod and destroying the engine.

It's probably a good idea to get it checked.
