Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
How long does the engine run before it begins to lose power and die?
Does the engine have the ready start feature? No choke, no primer.
This engine has an automatic choke that is built into the air vane and carburetor assembly. If the automatic is not pulling off as it should then it would cause the engine to run low on power and die shortly after started. Do you notice any smoke coming from the exhaust when the engine is running?
Can you remove the air filter and try to run the machine and see what happens?
You could have a carburetor blockage but I want to rule out these other possibilities before we go to that. You could also have a governor spring that has come loose as well which would cause the problem. We want to look at a couple more things but before I would do much on the machine myself, I would consider the age and the fact that you do have a warranty on the machine and it can be repaired by an authorized service center at no cost to you. I will continue to assist you as long as you need to help determine what is wrong.
Do you mow around or under any small shrubs or trees?
I was trying to find out if it was possible that you may have run under something that could have pushed the governor spring mount bracket backwards which would explain the loss of power and dying when under slight load. You could have a governor spring that has come unhooked. So yes there are several things that it could be and we have to use a process of elimination to figure out what has happened. As I said prior though, if the machine was just purchased in March of this year it has at least a two year warranty on it through the manufacture therefore you don't have to fix it yourself. The manufacture, Toro and Briggs in this case would repair it at no cost to you if you take it in to an authorized service center. There are just too many possible things that it could be and since I don't have the machine right in front of me I have to depend on you to check the things as we go through the process.
