Small Engine Troubleshooting Problems? Ask a Mechanic Now.
HI, my name is ***** ***** I am going to be assisting you.
Can you provide the model and type or spec numbers from the engine?
I was looking for the engine information. The information that you have provided is from the frame.
From the information that you have provided it looks like you have a single cylinder Briggs engine can you confirm this?
You had not been having any problems with the power prior to running through or under this bush is that correct?
The first thing that comes to mind is if it possibly caught the throttle cable and stretched it out or caused it to slip in the adjustment clamp at the engine, this would cause a loss of rpm or power.
Can you make certain that you have the spark plug boot or wire pushed firmly onto the plug, if this is not making good contact it would cause a problem.
If neither one of those are a problem the only other thing that I can think of is a valve problem but not sure what running under the bush would have to do with the valves.
Did the engine run okay for a little while after you replaced the spark plug?
Yes it could be of help.
It would cause the starter to turn slow but would not affect the running of the engine.
If the engine is cranking slow you could have a valve problem, this would also explain the engine running slow or no power.
I would check the valve clearances.
You could also have a carburetor leaking or over fueling which would also cause both problems. You can easily take a look at that, if the engine has been sitting for a while remove the air filter and look into the throat of the carburetor if you have fuel puddle there then your carburetor is leaking, you will need to clean and rebuild the carburetor. If you see no fuel there then that is not going to be your problem. At that point I would go back on focus on the valve clearances.
Let me know what you find.
