Re: emglo compressor starts but stalls quickly after
Its not getting fuel. There is a low oil shut off switch as well that go bad. most just bypass this unit. its connected to the on off switch as a 3rd leg. try that
if not check your fuel delivery. either the fuel line pet **** is closed/ clogged or a stuck needle in the carb is causing no fuel

if it now try's to start an just trips the breaker , then emglo's have a motor start capacitor that's in a small housing on top of the motor , heat from motor over time can make this go weak and not provide enough "start !!" to get it moving, replacements for these are avail and are not expensive
Where is it leaking from? If the unloader hisses for a few seconds when the compressor shuts off, it is working fine. If it hisses all the time when the compressor is stopped, it is still fine, but your in-tank check valve is toast. If it hisses when the compressor is running, you need a new switch.
I have a gas engine powered DeWalt compressor. I don't know about yours, but is there an unloader that you have to switch when you are starting?
Next, did you inform DeWalt, this unit is almost new(ly rebuilt) and they should take some responsibility for it.
You know, it could be that the motor has a starting problem, (bad capacitor, bad start winding system).
I have an Emglo compressor with a 8 HP Honda motor. The motor has a low oil level shut-off switch in the crankcase. My switch failed intermittently and the motor would run sometimes and not others. There is a wire going directly into the motor crankcase. On my unit, the switch is normally open and when there is enough oil in the motor, it closes to allow the engine to run. If you can't start the motor, unplug the wire that goes into the engine from the connector. Then stick a wire into that connector and hold it to metal on the engine & try to start the motor. If that switch is the culprit, it should now start.
Be advised that running the motor without the switch in the circuit would allow the motor to be run with no oil in it.
Emglo airmate compressors are set from the factory to shut off at around 125psi. There is an adjustment (remove cover to pressure switch) that will controll the cut-off pressure but it is not recommended changing the factory setting. There is also a safety valve installed that will open at about 160psi. It is a small brass device with a pull ring. When things go wrong with the pressure switch (rectangular box with power cord coming out of one side) the safety will pop open. There is a pressure regulator with round knob on panel that will lower the pressure to the tool, however this regulator does not control the pressure switch. Let you compressor run untill it shuts off and verify pressure to be about 125, if it is then all as well. Good Luck
