  Poor acceleration in your ICS Saw can stem from several issues. A dirty or clogged air filter can restrict airflow, so clean or replace it. Similarly, a clogged fuel filter can impede fuel flow, requiring replacement. An incorrect carburetor tune can also cause poor acceleration. Additionally, a plugged fuel tank breather or a blocked pulse tube can disrupt the fuel system, so repair or replace the fuel tank breather and replace the pulse tube.
