My sister picked up a generator last year on a garage sale for $150. It's a Generac 6500EXL. Electric start. It has a L5-30 110v plug and a 220v plug of some sort. I need to find out and pick up a plug for it.
I am planning on getting it running tomorrow. The battery is most likely shot. The oil has a definite gas smell because the previous owners didn't bother to shut off the gas. I am going to get it running and then check the float needle valve to see if its leaking. I can always shut the gas off and let the engine run out of gas. I will get the air filter cleaned out before firing it up. What kind of engine does this have on it? I am really not sure. It looks like a nice genny covered with dirt. |

I can't even guess on the engine brand, but you'll be albe to find it somewhere.
The carb probably will need a kit, but it won't hurt futzng with it to try and get it fired up. Somewhere on that engine are numbers that will give the parts store the info you need. Gnerac's website may have the info you need as well. When you get it running, I'd put about an hour on it and dump the oil again, especially if it does not have a oil filter on it. That plug is probably a 30amp contractor style 220v. If you can get it running and it turns out okay, $150 is a screaming deal on it. |

I think this is a copy of your owners manual... http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000034567.pdf thanks. I already downloaded it and the engine manual as well. I was surprised at how easy they were to find. Still can't find the engine brand. |

it is a generac brand motor. now, im not sure if they make them in house or have someone else make them but the couple i have dealt with have all been generac branded with no signs of another makers mark. I really looked it over and I could find nothing. Wonder how good they are? |

I really looked it over and I could find nothing. Wonder how good they are? Generac made their own "OHVI" (overhead valve industrial) motors for quite a while before Briggs & Stratton purchased the company. They're also referred to as the "Nagano" engines, since they were at one time manufactured in Nagano, Japan. They were made in several displacements, all built around a pretty robust design. The entire engine uses pressurized lubrication, supplied by a georotor oil pump - arguably superior to the splash lubrication typically found in small generator engines. An automotive-style spin-on oil filter was also present, allowing oil change intervals to be safely extended to several hundred hours (although not sanctioned by the manufacturer). The 8 dollar "Generac" oil filter can be cross-referenced to a Fram PH4967, which is also available for several bucks in generic form (Auto Zone "STP" brand, Wal-Mart "SuperTech" brand, etc.) I have a 4000EXL with the 7.8 HP version of the same OHVI design - If you need any additional info about them, let me know. |

Thanks Skibane. I had found the cross reference for the oil filter, but I am pretty sure you nailed it on the motor as well. I am picking up some oil and a filter later today. Its nice to know its a decent engine. I doubt this thing has been run longer than it takes to break it in if that. My sister got a great buy. |

I've heard of off-the-grid'ers using EXL generators to charge their battery banks on a near-daily basis for years on end - many thousands of hours of operation on 'em. OTOH, mine snapped a rocker arm at around 150 hours - a 15 dollar repair. Apparently, build quality can be hit-or-miss.
Jack's Small Engines has a pretty good inventory of parts for both the engine and alternator head. |

I got the genny running today. It took about 10 pulls to get it going, but then it raced really hard. Almost like at full throttle. Then I shut it down and restarted it and it fired up only running smooth on half choke. It took a while for the old gas to run through the carburetor until it finally started to run with the choke off. It ran very rough.
I tried plugging in a work light and it would not work, so no electric. What is flashing the field and is that something that I should try? How? |
|
If the engine speed is way off, the voltage regulator may be disabling any AC output. So, you might try to get it running smoothly first.
I had to flash the field once on my 4000EXL, so it's not unheard of with these models. Instructions on how to do it here. |
