I have a 18 4200 poulan chainsaw i have a new carb also new fuel lines it has a new coil there is plenty of spark but checking the spark plug after trying to start it show no fuel on the plug where to go next thanks for your help

Hi, i would start by making sure the fuel is on if that is an option on your saw. Then makes sure there is nothing obstructing the flow of fuel from the tank to the carb. You can check the lines by draining the tank the blow thru the tank with an airhose and make sure air is coming from the delivery line that hooks to the carb. if all checks out there, then you my hve a gasket on backwards inside the crb or your fuel flow screw needs adjusted. You can check to see if the carb has gas by gently loosining the drain bolt on the bottom. Another option is removeing the air filter and dumping a small amount of gas directly into the carb and see if it starts then. If it does then yo have a problem with fuel delivery from the tank to the carb into the cylinder head. Hope this helps.
