If you have a notched float it’s likely junk. They don’t last and will eventually absorb fuel. There is a better option but I won’t get into that.

Notched to fit around jet extensions? You know, I think it is. I think mine is brass, however. I'll have to pull the fuel bowl to if there is a problem with my float.

I've been running Holley's black nitrophyl notched floats for 25 years and never had 1 go bad.

Chris

I have rarely ever seen a bad nitrophyl float in many years of racing for those using gas, alky is a different story though.

If you have a fuel logged float, your float level will be higher than your original setting and in order to bring the float level back down to the proper level you will have little float drop which could cause that bowl's fuel level to get too low on a run and lean the motor out.

On methenol I’ve had them get heavy due to absorbtion. Float level will get high is first sign. Weigh them and it’s a dead give away. Just what I have experienced.

Same here, just had one do this a couple weeks ago. I replaced both and kept the old ones as spares. Been told you can let them dry out and reuse them later.

Got away from the brass floats. Kept crushing them in cold weather.

I've never had a problem with floats, but every spring my alcohol carb gets new metering block and bowl gaskets, and 2 new Quickfuel nitrophyl floats.

I carry spare needle and seat assemblies, but I've never changed them in 10+ seasons with this carb. I have changed the o-rings once.

Thank you everyone for all the thoughtful responses.
I have new needle and seat assemblies in-hand, have new O-rings on order, and will remove my bowls this weekend to see how my floats are.
Thx again,
Troy
