Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
Does this machine have a twin cylinder engine? My first thought is that you are only running on one cylinder which would explain the power loss.
Being a two or twin cylinder my suspicion would be that you are only running on one cylinder.
The first step that I would take is to remove one of the spark plug wires from the plug and try to start the engine. If it starts then we know that the opposite cylinder is running. Then replace that plug wire and remove the other one. If it still starts then we know that both cylinders are functioning and should not be a problem. However if it fails to start with either of the plug wires removed then we would move on to focusing on the cylinder that did not start. Or the cylinder that would not start with plug wire attached.
Is this a Briggs, Kohler, Kawasaki branded engine?
Let me know what you find.
So the next thing that I would look at is spark to the left cylinder. Are you getting spark to the plug?
Everything that you want to do from here would involve the left cylinder since you now know that it is not working.
Maybe as simple as a fouled spark plug. If you have a spare plug you might try changing it. If not maybe swap the two plugs.
I would move to a compression check on the left cylinder to make certain that it at least has compression.
It "blowing out" is at least a good thing. It would be nice to know exactly what kind of compression the cylinder has. If you want you can move on to removing the valve cover from the left cylinder and check push rods and rocker arms.
Two bolts in valve cover can be removed then you should be able to pop the valve cover off and check the push rods and rocker arms. I would be looking for bent push rods or broken/loose rocker arms.
Yes, you can come back here and continue our conversation at any time. I will not be available until around 7:30 tomorrow evening however.
