I bought a new carb for my 10 HP engine and now when it runs the exhaust gets red hot. The carb is an exact replacement for the original. How can I fix this engine so it doesn't flow red hot. It never did before I changed the carburetor.
Testimonial: "I already got that information off of the internet. The thing is how do I make that adjustment?? It only has one adjustment screw and it says it's for idle adjustment. It's a 10 HP Briggs and Stratton engine working a 5000 watt generator."

You might want to try this one but pricey thing, replace the carburetor! I have a 2008 Sears DTY 3000 25 HP two cylinder Briggs and Stratton Engine, I struggled for a year and half if it quitting when it gets hot. I replaced everything, Gas Cap, ignition module, fuel lines , filters , spark plugs, gas tank, exhaust / exhaust manifold and it all did not help. Due to the acidic (Alcohol added to the fuel) gas two the rubber inner control gaskets disintegrated causing "vapor lock" when the engine got warm/hot. Replace the Carb and then put additive into the fuel.
The only reason for a brush cutter to over heat is because the engine is running too lean, this may be because the fuel filter is blocked, or the fuel hose is leaking, or the carb is set to lean on the carb mixture screws,
Seems you have a blocked exhaust pipe, sure there is some exhaust coming out, but some chamber have small exhaust gas passage going through!
Check your engine temp and carb mixture too!
Hope that helps u out!
You got a couple of geniuses answering your questions. When he says it is getting red hot, he means that it is glowing red. Hot air passing through the muffler from a normal running machine does not make it get red hot, mowerman. And there are more reasons then the 2 you list mrfixit. The likely problem is your jets in the carb. It sounds like it is running to rich. Play with the little screw on the carb a bit. I think you would have to turn it in a bit. Wish you luck.
It won't be valve timing or clearance. The fuel/air mix would be the culprit. Clean the carburetor with special attention to the idle circuit. Remount the carb with new manifold gaskets. A manifold air leak will mess up the mixture. Also, get a new spark plug one heat range colder than stock. Hope this helps out!
The most likely cause is that the motor is running very lean. Make sure that all of the componets for the air intake system are connected and not leaking. This can happen if you have changed to one of the new high flow air cleaners like K&N. This causes the air/fuel mixture to have too much air and not enough fuel (lean). If you can adjust the carb then make it richer.,
