Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.

Juan, after you replaced your carburetor, did you change your engine oil?

Expert:  Donald replied 3 months ago.

The smoke you are still seeing, is likely causes left over oil that remained inside your muffler, from before you replaced your carburetor. That oil will eventually burn from your muffler. Change your engine oil, and allow your engine to run long enough to burn the oil from your muffler. Afterwards, I believe your engine will be okay.

my question was about the mark on the cylinder itself and it has not been answered, and I have already cleaned the muffler of oil. WHAT ABOUT THE MARK ON THE CYLINDER HEAD??????????
Expert:  Donald replied 3 months ago.

Thank you for clarifying. Is your engine Briggs & Stratton? Do you have the model numbers for your engine? I will pull up your engine and check for the mark on your cylinder.
