Etq tg3000 portable generator is leaking gas from carburetor into air filter. Any suggestions

SOURCE: Generator with Briggs & Stratton,no gas is getting in carburetor

The needle valve may be stuck which would not let gas into the carb. I don;t think rebuild kits are too expensive. Pull the carb and take it to a lawnmower repair shop and they should have the parts. Before that though pull the bowl and make sure it has gas in it. If no then remove the fuel line and make sure gas flows from it. If no then could be the fuel shutoff valve is not operating properly or junk in the gas tank is obstructing the line.

First thing to check is to see if the generator is actually turning--couplers sometimes fail. You need some electrical skills and a voltmeter to trace down problems in the generator beyond checking the health of the two brushes that supply current (< 115 volts DC) into the rotor field circuit. You can find wiring and schematic drawings on the Troy-Built web site, just look for the 030248 model. Another person that I worked with had a similar unit with the same problem. It looked like the voltage regulator board was the problem, but haven't heard back if he had fixed it.

There will be a normal odor as the engine cranks until enough gas is in the intake for starting. Gas generators do not have an ignition 'on-off' switch, they use a fuel solenoid to turn on and off the gas to start and kill the engine. If you are uneasy, your local gas company should be able to check engine compartment for leaks. Here in my home town, the gas company will inspect any equipment for gas leaks and/or carbon monoxide levels free of charge.

Testimonial: "Tks for the feedback on this problem, it is very informative. The faint gas odor persists when idle. Would this suggest a defective solenoid."

Hello Pete,

Is fuel actually leaking from the bottom of the bowl, or is leaking out the air filter and running down to the bowl?

If the former, then your bowl bolt's gasket has likely deteriorated. This would allow fuel to run down the bolt itself. Note that some carburetors will have a fuel shutoff solenoid (to the engine, not to the carburetor) that holds the bowl on, rather than a bolt. There will still be a gasket though. Turn fuel off before trying to service.

If fuel is running out from inside the carburetor (through air cleaner, etc), then you have a float / needle that is stuck. This is quite common after a small engine has been in storage and fuel was left in the carburetor. The residue causes the float to stick to the bottom. Turn the fuel off, undo the bolt that holds the bowl on, and carefully remove the carburetor bowl. Use a can of carburetor and choke cleaner to spray out the "gunk" in the bowl, spray off the float, and then reassemble. If it still leaks, then your needle seat will need to be replaced as well.
