Hi everyone,
I often work on both ATVs and larger construction equipment, and I’m always on the hunt for solid OEM manuals—service, repair, and parts. The usual searches give a lot of random PDFs or unofficial scans that aren’t very trustworthy.
What online sources do you all use when you need a factory manual quickly? Are there sites you’ve found that consistently provide genuine OEM content for ATVs or heavy machinery?
I recently came across Heavy Equipment Manual, which claims to provide verified OEM service and parts manuals (covering brands like Caterpillar, Komatsu, Kubota, etc.). Has anyone here tried it, or do you have other go-to resources you’d recommend?
I’m interested in options that are:
· Fast to download
· Cover both heavy equipment and ATV models
· Clear on licensing and safety
Thanks for sharing your experiences and any recommendations!

If anyone is having issues with the Mikuni VM24SS carb, I thought I would post what issues I had and how I resolved them.
Acquired a 93 Bayou 220 that had sat for over 4 years.
The carb was extremely corroded and pitted and full of leftover fuel.
Cleaned carb and bowl and was able to get the engine to start.
Within 30 seconds exhaust would heat up and start to glow red hot.
Removed carb and recleaned everything, including a second overnight soak.
Needless to say, after removing the carb for the 5th time and my frustration to the limit I
realized that my attention had been to the carb body and not to the bowl.
There is a small brass rod on the bottom of the carb that goes down into the float bowl but is seperated from the main section. I had cleaned that area very well....I had thought.
***The corrosion had sealed off the channel that runs from the main bowl section to the small tube section on the side of the float bowl. No amount of carb cleaner was going to get it to budge. So i took a small nail and started to scrape away the corrosion and was eventually able to dislodge enought of the corrosion that carb cleaner would flow through that channel. ***
I thoroughly cleaned each side of the channel in the float bowl and reinstalled the carb and now the issue of it running lean is gone.
On a second note the fuel mixture screw was a nightmare to remove as the threads had been corroded and wouldnt let the screw come out. I used a little cutting oil and worked the mixture screw in and out until I was able to push past the corroded threads and completely remove the needle. After a couple passes with a tap to clean the threads it is like new again.
Hope this helps if you are having a lean running machine.

Hello, would something like this work for cleaning jets in a MIKUNI BST40-251 carburetor? If not, suggestions would be appreciated I'm wanting to put an OEM rebuild kit in the original carb and put it back on my 2005 500 Scrambler 4x4 Thanks! 🙂 Tool Shop® Standard Tip Cleaner at Menards®

My 2018 Polaris Sportsman engine operation feels jumpy when I ride. It happens when I am trying to keep constant speed and throttle is fixed position. ATV will misfire and feel jumpy. Not smooth..
Idle is good more or less. Will always crank up on first attempt.
I am thinking to start using carbon cleaner.
Any different between the Polaris carbon clean and Seafoam?
