TJ5208 1,824 #127 Posted January 30, 2022 (edited) Might take the blade off the 520-8 tomorrow just want to get some pictures without the blade on there it's not too hard to take off and put back on and then I can just go out and ride around without having to worry about that hitting anything Edited January 30, 2022 by TJ Salyers 1 Share this post Link to post Share on other sites

lynnmor 7,307 #131 Posted February 1, 2022 Get NGK # TR4/3754 or Champion # RS17YX/909 spark plugs. The NGK are better, Champion no longer produces a quality product. Hopefully the heads aren't ruined from the wrong plugs being installed. I think you need to back up and go over this engine properly and skip the joy riding till it is done. For example, I haven't heard that you did a valve adjustment. We stand ready to help if you want to do it right. 2 Share this post Link to post Share on other sites

Would I need to do a valve adjustment because the tractor was only used to plow snow sorry just trying to make sense of what the valve adjustments do I've been trying to study up on this engine. 1 Share this post Link to post Share on other sites
TJ5208 1,824 #133 Posted February 1, 2022 (edited) As Dan @Achto and my dad says if it ain't broke don't fix it because you might do more damage than good. Edited February 1, 2022 by TJ Salyers 1 1 Share this post Link to post Share on other sites

Valve adjustment and decarbon of the heads is regularly scheduled maintenance of an Onan P series engine. Doesn't matter what it was used for. 2 Share this post Link to post Share on other sites
TJ5208 1,824 #137 Posted February 1, 2022 (edited) Im not saying I'm not listening. But I can't do it. I don't have the equipment to. Edited February 1, 2022 by TJ Salyers 1 Share this post Link to post Share on other sites
Handy Don 12,235 #138 Posted February 1, 2022 5 minutes ago, TJ Salyers said: Im not saying I'm not listening. But I can't do it. Two years ago I re-did a P218. I'd never worked on a twin before and was very intimidated by the (to me) complexity. With encouragement from this group, I went at it slowly and carefully, step-by-step, and it came out quite well. Yes, I did bring some applicable mechanical skills and tools to the party from other work I'd done, I had a sheltered place where I could leave the "work in progress", I enjoy researching problems to find solutions, and I had the time to learn before doing. Plus, I was game to give it a go. I have friends expert in other areas, though, who don't know a carb from a differential and simply don't care to, so I fully recognize that for your own reasons you aren't going into this machine. All of that said, I encourage you to start looking now, before you have the pressure of an urgent need, for a shop that you're willing to trust to do the necessary preventative maintenance at a price you find fair. Good luck! 3 1 Share this post Link to post Share on other sites

kpinnc 12,083 #140 Posted February 2, 2022 (edited) And if you don't want to decarbon the heads, use some seafoam in the fuel. Or a healthy dose. Always. Of course I use it in everything that runs on gasoline anyway... Edited February 2, 2022 by kpinnc 2 Share this post Link to post Share on other sites

kpinnc 12,083 #142 Posted February 2, 2022 TJ, take a look at this link. These manuals are written so pretty much anyone can get in there and perform scheduled maintenance, or even up to full-on rebuilds. If you hit a snag, post up your question. Most anyone here can help you. https://www.wheelhorseforum.com/files/category/14-onan-service-manuals/ 2 Share this post Link to post Share on other sites

TJ… I’m not by any means telling you what you should do… it’s your machine. B U T… a valve adjustment is not that hard. I did it to my P220 Onan, and I am not a small engine mechanic by a long shot. Before you tear into it, watch some videos on YouTube, check here for videos and pics with instructions, and as @lynnmor has said “We are here to help.” There is also an Onan P series engine shop manual on here that you could download also. I downloaded it to my phone, emailed it to myself, and then had it printed so I could have a paperback manual… I read things better out of a book than I do off of a phone screen. Yeah, you may miss out on some seat time while you order Genuine Onan parts such as intake and exhaust gaskets, valve cover gaskets, and other items needed to reassemble, but you will get more out of the engine if you try to maintain it best you can.
