Reply To: Correct level of fuel in carb bowl for 1924 2hp BNL Johnson

[George Emmanuel]

I’m going to display my level of ignorance and make a guess as to the answer…….Isn’t the fuel level in the float bowl supposed to be close to the top of the nozzle/emulsion tube in the throat of the carb such that fuel can be pulled out on the intake stroke?  If it weren’t then you probably couldn’t get the motor to start. Once it is running, the constant suction continues to pull fuel until the float bowl is depleted.

That being said, the level is somewhat critical. There are some carbs with the pump primer where the float bowl feeds the primer chamber, and I’ve experienced issues where the fuel bowl level has to be high enough for fuel to enter that passageway elsewise you can pump all day w/out starting. My SportFour is an example as it does not have a choke, –only a primer.

Am I correct?
