650 mighty demon fuel bowls

This might be a stupid question but its bugging me. Are the fuels bowls suppose to keep fuel in them at all times or if the car sits for a couple days do they empty back into the fuel line because the lack of fuel pressure.

Re: 650 mighty demon fuel bowls

The fuel bowls should retain fuel when the engine is off and sitting for
long periods of time.

The fuel inlet located high up on the bowl and even if a little fuel went
back into the supply lines, there should still be some below the site level
plug.

Check the fuel bowl gaskets, or intake manifold plenum area for fuel pooling. You might have a leak.

Re: 650 mighty demon fuel bowls

Could it be possible that the power valve is blown ?

Well i just got home and checked the carb. The fuel inlet is right in the middle of the sight glass. The fuel is right under the sight glass so if i rock the car a little bit you can see it slush around. So im guessing that the fuel is emtying back in to the fuel inlet since the bottom of it lines right up with the bottom of the sight glass.

Re: 650 mighty demon fuel bowls

That's pretty much where the level should be.

The bowl will never be 100% full because the float will rise and close the
needle/seat valve.

From what I can tell your fuel settings are correct.
