My craftsman 123cc snowblower starts and then shuts down. Can Sea Foam help? [SOLVED]

Thanks for the question, Charles.

What you’re describing is very common with small engines that have been sitting. In most cases, this happens because fuel gum and varnish formed in the carburetor while the fuel sat. That residue restricts fuel flow and causes engine problems.

If fuel varnish is the issue, Sea Foam can help clean it up. The best way to do that is to use a high concentration of Sea Foam Motor Treatment (or High Mileage) so it can clean the gum and varnish quickly and effectively. Here’s what I’d do:

• Drain the fuel

• Add a high concentration of Sea Foam and fresh gas (up to about a 2:1 ratio of gas to Sea Foam)

• Run the engine as long as you can to pull the treated fuel into the carburetor. If it won’t stay running, prime it or pull the starter rope several times to help draw the treated fuel into the system

• Shut it off and let it sit overnight

• Start it up the next day and let it run for a while

Once it’s running normally again, you can switch to adding 2 ounces of Sea Foam per gallon of fuel to keep the fuel system clean and help prevent this from happening again.
