Poulan Gas Hedge Trimmer Replacement Parts For Model GHT220 (Type 5)

Hi Denis, Thank you for your question. The carburetor needs to be set. Here are general instructions for a 2-stroke carburetor. There will be 2 idle screws. One will be idle mix and the other will be high speed. Turn both screws in to shut off the fuel then back off 2 turns, next start engine, it may not run great, but should start at these settings. Start the motor, and let it run for a few minutes to warm it up. You may have to fiddle with the throttle a bit to keep it running. Slowly turn in the low-speed jet, until it starts to die, then back it out another 1/4 to 1/2 turn. Next, hold the throttle wide open, and slowly turn in the high speed, until it really starts to smooth out and rev high, and start screaming, then back this out until it starts to run rough or slow down, and then turn it back to the midway point between these two positions. Keep playing with the low-speed needle until you get rapid immediate response from the throttle and good idle with the idle adjustment. Then play with the high-speed needle, but always back it out from the setting about 1/4 turn or so, from where it runs the smoothest. This setting of backing it out will allow more fuel when under a load and keep your 2-cycle motor from running too lean. Put a load on it and just tweak the settings just a hair at a time. If you are in the ballpark it will not take much adjustment to make a difference. If you have any questions, please let us know. We are open 7 days a week. We look forward to hearing from you!
