How to fix ?
Most of the time, this is caused by debris in the mower deck that is blocking the discharge. Simply cleaning out the mower deck can often correct this issue and prevent the smoke from reoccurring. If it doesn’t, the problem may be with your blades. Consider replacing them or having a mechanic take a look and attempt to fix the issue.The other fuel-related problem could be the fuel control lever on the engine itself. If it’s jammed closed, it will keep the fuel from getting to the engine even if the fuel filter is clean. First, determine why it is jammed. If it still moves, consider spraying down the moving parts with lubricating oil to get it moving again.
