Can I add Sea Foam to an ATV that’s cutting out and back firing? [SOLVED]

Thanks for the question, Michael! Yes, you can use Sea Foam. If the problem is caused by fuel residues or varnish (which is often the case), Sea Foam can help.

Here’s an article on our site about fixing an ATV that’s running rough: https://seafoamworks.com/how-to-fix-a-quad-or-atv-that-is-running-rough/

Here’s what I’d do: add a whole can of Sea Foam Motor Treatment to a low tank of fuel and run your quad for a few minutes (10-15 if you can) to get it working through the fuel passageways. After that, shut it down and let it sit overnight to hot soak and clean. After you fire it up and run it again, you can add fresh fuel to the tank. The Sea Foam should clean up any fuel residues or deposits that are causing trouble, if they are the cause.
