Briggs engine wont pull fuel

6 hp i/c engine mulching mower.If the gasket between the air box and the carb is damaged will the carb not pull fuel from the bowl?I have cleaned the carb 3 times and checked the float operation.I have a new gasket but was curious if it will help.

Davo, does that Briggs have a bowl and float carb, or is it a diaphram type? I know that both will run without the air cleaner installed, so I don't think the gasket is an issue. The bowl type is gravity fed for the fuel, diaphram type uses intake vacuum pulses from the carb throat to move a small diaphram fuel pump inside the carb to supply the metering jet. If the diaphram has a small hole, or if it has set up for some time and become stiff, it won't pump right. Engine won't run.

Thank you for your reply.I found that the gasket affects the primer bulb circuit of the carb, also throttle cable slipped so it would not adjust to fast properly.Runs good now I was helping out a neighbor.Thanks again,Davo
