My Homelite Trimmer (approx 8 yrs old) will not accelerate. It starts fairly easily and idles well. When the throttle is opened however it splutters and dies. Sometimes (rarely)I have been able to rev it but even then it is gutless. I have replaced the fuel filter and fuel lines. I have also blown compressed air through the "LOW and HIGH" jets. I have set the "High" adjustment screw at 1 and 1/4 turns from bottom. All diaphragms and gaskets appear to be in good condition. Any input would be appreciated.
Thanks P.G
