There’s a good chance that Sea Foam can help depending on what’s causing the problem. Sea Foam in fuel does a great job cleaning up gum and varnish in a fuel system. Gum and varnish is a very common cause of engine trouble like you’re describing in small engines. So, if the problem is caused buy a dirty fuel system, Sea Foam in the gas will probably help.
Assuming you’re talking about a small engine, here’s what I’d do:
Add a high dosage of Sea Foam to a low amount of fuel. For small engine equipment (like chainsaws, weed wackers, anything with a small tank), use a 1:2 ratio of Sea Foam to fuel. In something like a 4-wheeler or larger mower, add at least 8 ounces of Sea Foam to a low amount of fresh fuel in the gas tank – try to be around 3 or 4 parts gasoline to 1 part Sea Foam.
Start the engine and let it idle for 8-10 minutes to allow the Sea Foam mixture to flow through the carburetor circuits, then shut off the engine. [If an engine does not run or won’t idle, remove spark plugs and crank or rope pull the engine several times to draw the concentration through the carburetor circuits.]
Let the engine sit to soak for several hours. Overnight is great, or soak up to three days if you have the time.
Run the engine after the soak period. Once the engine has idled for at least 5 minutes, add more fresh gasoline and let it idle for another 5 minutes. Then operate as normal – more engine compression and heat will increase the rate of cleaning.
If you’re talking about a vehicle, it’s also worth a shot, though it very likely could be caused by something else. Wait until you have a very low tank of fuel (1/8 tank or less), add an entire can of Sea Foam High Mileage, and drive it until almost empty before refueling with fresh fuel. That will do a great job cleaning and help the problem if it’s caused by a dirty fuel system.

Thanks for the question, Ann.
