42515X92A (2000) Murray Lawn Tractor - Overview

Hi Mary, Thank you for your question. If your riding mower has smoke coming from it, there are some parts that you will need to check to see which one is causing the issue. If the smoke is white, you will need to check the piston ring and the breather. If the smoke is black, check the carburetor and the air filter. These parts may just need to be cleaned, if they show signs of damage or wear, you will need to replace them. We hope this helps! Good luck with the repair!
