Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, my name is ***** ***** I am going to assist you with this.
Your problem is still in the carburetor.
Sometimes, even when people think they are cleaning them, they are not doing it correctly, and sometimes a carb is just too far gone to be cleaned, and must be replaced.
Cleaning involves completely disassembling the carb, cleaning each individual piece, spraying/poking out every hole in the carb, spraying it again, and drying it.
If this does not work, then the carb must be replaced.
Without being able to see the screws, I really can't say.
Are they star shaped? If so, those are Torx screws, and require Torx bits to remove.
I understand you are in a hurry, but this is why you can't wait to the last minute to check things out.
