Hello,
Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
The smoke depends on a few things such as, if it has been converted to pre mix, then it will always smoke more than it does/did when not pre mixing oil/fuel, if not then it depends on what color the smoke is, given the symptoms it is most likely excess fuel or incomplete combustion. See how it runs with fuel cap off and if it runs fine then you will need to check the vent valve and line if not and no change with fuel cap off then check if it has the gray fuel lines and if it does then you need to start there first. Replace all gray fuel lines with uscg or black rubber fuel hose, clean filter and or replace and then professionally clean and rebuild the carb also replacing the internal filter in it and the cleaning and rebuild of the fuel pump.
Also check compression.
Thank you!
- Joe
