Carburettor heat in Spits and Hurri

[SlipBall]

[QUOTE=Blackdog_kt;395419]I was thinking about this too. Running on warmer (meaning, rarified) air means less air volume for a given fuel volume. It's just like running on too rich a mixture = power loss.

Or does the system just heat the carb from the "outside", resulting in simply warming the "tube" and not the air in it?[/QUOTE]


Yes, that is true...basically like a radiator tube as found in your car, or home effect see #18/24 in dia...would be curious to know if there was a control lever for restricting flow

It would also ensure that any liquid fuel (from the accelerator pump) that hit the carburettor walls would vapourise quickly giving better throttle response.

Until I saw that diagram i didn't know that they had an accelerator pump. I didn't think they were that common in aero engines.
