Carb fuel inlet seat

[JeremyK5]

Which would you use?

I'm in the middle of rebuilding my carb, and the replacement seat for the float needle is different from the old one. I'm wondering if there's any advantage to having the slots in the sides.

I'd use the one with slots.

My feeling is that the fuel coming in is going to much more easily fill a float bowl trying to empty. Less resistance to flow if it doens't have to overcome that little bit of additional height.

IIRC Doug Roe's book covers this, and said that the solid one flows better. I don't see how that is correct.

yep, allows fuel into bowl a hair more quicker after its past the seat, thats all

pretty basic

really is up to you,

personally i dont care which i run, they all work fine, worry about soemthing more important like clogged jets, and dirt, cleanliness is godliness in carbs and engines and shops,

usually i dont change the seat for a new one unless the needle was very badly worn

good luck
