Will rich carb make engine run hotter?

If my carb is running really rich, will that make my engine run hotter?

Re: Will rich carb make engine run hotter?

I dont think that would be one of the zillion harmful things from a carb running too rich.

I always thought it was too lean that made it hot.

my memory may be hanging me out on that one though.

I guess if ti was running so badly from teh rich condition it could generate more heat than when running correctly.
I had always thought that the oxygen burned hotter than air, and there for leaner=hotter.

We will find out soon, when someone who knows for sure chimes in

Ozark is correct, running rich actually lowers the temp in the combustion chamber and therefore lowers the temp of the engine as a whole.

Re: Will rich carb make engine run hotter?

The rich condition you speak of will definitely result is lower temp combustion. Here is where the problem begins though. Do you run a cat. converter? If you do, the rich condition may be plugging it up resulting in a loss of power and increased back pressure which could increase heat in the headers/head. I've seen some seriously plugged converters from running rich/buring oil. It ain't purty.
