Default Onan 2.5 LK

I apologise if I am wrong for starting out in the wrong place. I just picked up a 2.5 k Onan generator for 25 bucks at an auction. I know next to nothing about generators. It is not running and I would greatly appreciate if anyone could help me with information on it. The model number is 1R/L0545J and the serial number is 0573649394. I just thought it would be fun to bring her back to running shape.

I am a dunce, if y'all need to email me anything I can be contacted at harleyfan88@hotmail.com

All the manuals you need will be here for free:


Look here for manuals:

http://www.twinslan.net/~n0nas/manuals/onan/

Once you open link then hit control and F, then up at the top left will be a search box, type in 2.5LK and hit search and the model will be highlighted.

I believe all the LK sets were 1800 rpm.

$25! You got a deal, as long as it turns over and is mostly complete, nice job!! As stated above, manuals are free and downloadable. Advice and help on here is also a huge knowledge bank. Most of the folks on here have forgoten more then I will ever know.
I too have an LK that is just about next on the list to get repaired and back to its old self. From what I have read and found out they are a nice unit.
Post some pics of it. Go down to manage attachments and pic the file you want to load, then hit the download and when they finish loading, hit the close window and then post. Hope I remembered all the steps, Oh well, congrats on the green beast and welcome!

I have been trying to find the answer to this question several different ways and I feel like I have been chasing my tail. I broke the main needle jet while I was trying to straighten it out. Does anyone know what the Walbro part number is so I can get it from them or am I going to have to go directly to Onan?
