SOURCE: I have a 25 gal compressor and it will not build

You got a good life time with this. The compressor has seals or "rings" which wear out over time. Replace them and your compressor will love you. It won't hurt to check all the lubrication points. This procedure is easy for even a novice but may require a special tool. Go to your local small engine repair shop and ask. They will be glad to help you.

Probably the check valve has failed. It apparently is where the pipe goes into the tank from the compressor.

SOURCE: compressor won't build psi above 30,is this

Or maybe someone has played with the Regulator and adjusted it to this????

Try readjusting the regulator first and if that doesn't work, get a new regulator.

Hello I have a 20 gallon kobalt model 033204. I just replase pressure switch but does same thing. When I tur on the compressor jus build 50 psi and shuts off.

This usually occurs when the motors internal thermal / amp breaker opens due to overload or weak breaker. Use an amp gauge to test for too much amp draw. If amp draw is normal, then problem could be the in-tank check valve leaking pressure back to the pump overloading the system, or weak capacitor or weak breaker. Bypass the breaker temporarily if the amp draw is normal to test system. Good luck

Craftman lawn tractor

the newer fuel has been giving problems to the rubber seal for the needle and seat in the carb so what happens is the carb over fills with gas and then flows into the intake and crankcase then when in the cylinder it hydrolocks not letting the engine turn over change the needle and seat in the carb change the oil add a shut off valve on the fuel line and shut it off when not in use and if storing for more than a few days run the carb out of gas by shutting the shut off valve and let it run out of gas in the carb this will reduce it happening again

My compressor will not go over 20 psi i have a craftsman 921 4 gal 125 psi compressor and it will not build past 20 psi i do not know how to get to the pistons and stuff what do i do?

The problem with compressors not building pressure is usually a bad pressure switch or bad regulator. Does the motor shut off at 20psi or does it continue running and not build pressure? If the motor continues to run with no increase in pressure, the you should go over the machine looking for air leaks from your regulator back all the way to the motor. Any air leak while the compressor is running can cause the pressure to "peak" way before the intended shutoff that it is regulated to.

It will not build pressure in the tank.

There is a pressure relief valve somewhere around the motor. Make sure it is closed. If the relief valve isnt leaking air while the compressor is running you probably have a loose hose on the line going from the compressor to the guages or the overpressure valve. Something under the motor/compressor cover.

Car stalls when oil pressure drops...20 minutes to restart

No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!

Alero will crank awhile before it finally starts w/ more details

May have small fuel leak or fuel pump sending unit leak down. Or fuel pump psi low.

After 30 minutes try this turn key on. do not try to start wait 10 seconds turn key off then on again 10 seconds then try & start if it starts right away fuel system is losing PSI either back through the fuel pump or a leak in line. If you can find no leaks would suggest replace fuel pump & assembly.
Another possible but rare fuel injectors may be leaking fuel over time & dropping PSI needed for start up.
