Open Question

I have a Northstar (13,000 watt) generator with a 20hp. Honda 630 motor. In order for the motor to run smoothly, the choke has to be pulled half way out. It does not matter if the motor is running und

I purchased this generator at an auction. It does not have a warranty. It does not look like it was ever ran. It had no oil in it, no gas and the spark plug was new. No hours on the hour meter.

SOURCE: cranks fast but wont start

Hi, You did a good job of diagnosing your problem. Gas in bowl and dry plugs, starts with fluid, But, to quote you, "won't go through carb" . If you feel confident, you should disassemble and clean the carb, as that is going to be the problem. As a tip, if the genset is going to sit make sure to turn off the fuel flow to the engine and run till the engine dies. They do not like to sit any length of time with fuel in the carb. Good Luck, this should Fixya!

SOURCE: There is absolutely no voltage output. What

My generator has a switch to turn on the output, you must turn it "ON" to get power.

SOURCE: low output from NorthStar 5500PPG

There are a few scenarios that can cause this.

1) The extension cord that you are using is too long / too light of a guage. Try a heavier extension cord, or plug directly into the generator.

2) The alternator has lost its "residual magnetism" and may need to be reflashed. Consult Northstar for instructions and details.

3) The voltage regulator (actually a simple capacitor) may be "weak"

4) The diode for field winding may be bad.

You can get a copy of your manual here, page 40 has diagram and part numbers.

How to start the generator


Hi Joe, I had asked for a little clarification and have not received any information. I will answer this question based on the generator is in good working order and it is a recoil start. Open the petcock, (this is the fuel valve) and give it about a minute to fill the fuel bowl on the carburetor. If your generator has an engine an on/off kill switch, set to on. If the generator has an auto idle switch set it to off. If the engine has a throttle lever located under the carburetor, push it all the way down (full throttle). Pull the choke knob out completely, there is a detent on the choke for half choke, pull it past this for full choke. pull the recoil starter rapidly. As soon as the engine starts running push the choke knob to half choke, this will allow the engine to run smooth while it's warming up. Depending on the climate that you are in, warm up time will vary. After a minute or two in cold climates start pushing the choke knob in, if it starts to run poorly pull it back out too the half position and let it warm up some more. When you can posh the choke in without the engine faltering it is ready to go. In warmer climates you might be able to start the engine without the choke or in the halfway position. Robin Subaru makes some of the finest small engines available. I would choose a Robin over a Honda every time. I hope this gets your generator going, and once again this is based on the generator being in good working order. Good luck, Michael Burke.

How loud is the NorthStar 13KW trifuel generator ? thank you


Probably around 76to 78db if I were to guess . Its not alway best to be adding extra mufflers to these engines that were designed with the one they have . Adding mufflers change back pressures and temps on exhaust and effect the performance. Very nice generators. Hope this helps.....

Honda 5500 Generator


If you have checked the stator, rotor and brushes and they appear alright then it is probably a voltage regulator. The honda dealer can run a test and confirm the problem at very little expense. It cost me 25 dollars Canadian to preform the test and it was well worth the money because you cannot return electrical parts and they can be very expensive. Have a great day!
