Do you maybe have regular gas in it? Both Canadian and US regular gas now have ethanol in them and if the generator has sat for 2 weeks or longer then the gas is bad.Remove the gas tank and look inside. You will probably see an off-color blob floating around in the bottom. That is our wonderful environment friendly ethanol doing what it does best. Drain the tank and refill with premium. Restart the engine and do what you need to keep it running for about 5 minutes. If it has the plunger primer for cold start, use it every time the engine starts to die, 2-3 pumps each time. If not dribble a little gas into the breather to keep it going. After about 5 minutes it should start running on it's own. If not you will likely have to remove the carb and get the rubber seals replaced. Ethanol and rubber don't mix well.

After this keep premium gas in all your small engines. It doesn't separate. If you want to keep using regular gas then there are additives in the after market that will help keep it from separating. Hope this helps.

Diesel engine runs then stops then runs stops every few minutes


Mate I use to drive a freightliner and it cut out on me one day, I eventually got it started but cut out again after about 5 minutes, I rang a mechanic to come out and he found a heat sensor wire came off the radiator and that caused the motor to cut out... Hope I haven't wasted your time.......

I have replaced my fuel pump, filter, throttle position sensor, and relay on my 1992 jimmy. it runs but everytime it hits idle speed it cuts off. what could that be


It should have an idle air control valve which lets air into the intake to control the idle speed. The valve could be faulty, or dirty, or the throttle body could be dirty. The computer opens and closes the valve to regulate idle speed.

Drivers side window goes down 6" and stops. how do i remove the door panel to get access to the window mechanism to see what's stopping it?


The circuit breaker that is built in to the power window motor is weak and keeps cutting out.
When the window stops after a couple minutes it will move a bit again. That would be a faulty power window motor. You have to remove the complete window regulator system to change the motor.
There are 2 screws in the armrest by the door handle and plastic clips all around the door panel.
There is a hidden screw in behind the light at the back of the door panel if it has one.

It sounds like your alternator might be starting to go bad and the Battery Light is coming on because it is not charging the battery correctly. Have your Alternator checked with a volt meter, it should be reading 13 to 14 volts if working correctly. If not, replace your alternator.
