Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** and am happy to assist with the problem you are having.
First, since you said it ran the day before, we can rule out a few things. We knew it was getting fuel and spark but one of those might have become an issue. The first thing I would like you to check is for spark by installing a spark tester inline and then cranking the engine. These are available at most auto supply stores. If you do have spark, then remove the spark plug and see if it is wet with fuel and then let me know what you have found and we can investigate this further.
OK, so we know it has those two items, we will concentrate on the fuel side of things. Is there a way you can take a fuel sample in a glass jar or beaker and see if there is water in the fuel?
Since you put fuel in it the other day, I want to rule out if water has now settled in the tank and into the carburetor bowl. If you can shut off the fuel and drain the carburetor bowl, that is also where we need to see if water is in there.
