Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. I will need to ask you some troubleshooting questions as we go. Have you tried a new spark plug?
Okay. When you had your muffler off, did you check to see if your piston, or cylinder was scored?
Thanks for this information. Do you have a compression tester?
Did your gas leak into your cylinder?
I understand. Are you near your saw?
For troubleshooting purposes, I would like for you to do two things. First, check to see if your spark plug is wet. If it is not, spray a small burst of carburetor cleaner, directly into your carburetor. Let's see what happens.
Keep in mind that an engine need three components, in order to start up and perform to your satisfaction. An engine need Fuel, Spark, and Compression. You have already confirmed that you are getting fuel, and spark.
This is why I asked about a compression tester.
Have you completely resolved the flooding issue?
Yes I will be here. Thanks!
Thank you for checking for me. Your compression is too low. Your compression needs to be a minimum of 90 psi., although I prefer 100 psi. or above.
You will need to determine what is causing your drop in compression. You could have stuck rings, or a leaking gasket. Also, check the four screws that secures your cylinder to your crankcase. Check to see if they are tight.
Your piston and cylinder looks good, when looking through your exhaust ports. Check also from your intake/carburetor side. I will be here until 10:00 pm central time tonight. I will be back online at 5:30 pm central time tomorrow.
You are very welcome! Just check everything closely, I believe you will discover where our problem lies.
Yes, I am back with you. How are you today? I have been waiting to find out what your investigation revealed. We can continue from here. Thanks!
Good morning! Thank you for checking your engine. Yes, your compression need to at least 90 psi or above. 40-60 psi, is too low, for your engine to start up.
