On the atom edger where are the positions of the fuel lines. Bought one with none on them. Any help will be great. Thanks

If you're referring to the grommet where the fuel lines enter the fuel tank, just go into any mower shop and ask for a Ryobi tank grommet. It is effectively a generic item and is interchangeable with almost all 2 line grommets.
Alternatively, as an Atom dealer, I could order the genuine part in for you.

Make and model of the tool will aid people in answering your question.

Your local hardware store and ebay has a great supply as well.

You can find replacement fuel filters at a nearby hardware store. Once you have one, fish out the line from inside the tank and fit new filter onto line and place it all back into the tank. You will probably have to back out the tube a little after re-installation.

Possibly a fueling issue, stale fuel, wrong fuel/air mix

#1: Atom arc rod is very good and expensive rod comparatively speaking. 8018 is similar to 7018. It is an all position rod but instead of 70,000 pound tensile strength , it has 80,000 pound tensile strength.7018 is commonly used in repairs or steel construction 8018 is used in appilcations where the need for a higher strength or stronger weld is called for . Usually when welding higher grade steel than A.-36 It can be used in place of 7018. 5/32 calls for 150+ amps. 1/8 is a more common size.Remember Atom arc is top of line but finding someone who will pay the difference or needs this rod may be hard to find.

Gunner, you may want to;
inspect the lines for pinches or cracks,
clean or replace the fuel filter
replace the carburetor fuel pump diphragms/gaskets, and inlet needle
remove any adjustment needle for cleaning with a spray carb cleaner

Hi ken If your machine has 2 holes in the tank it must have a primer first of all you you must fish out the pick up filter from the tank feed your new fuel line into one hole and out the filler hole connect the filter & put it back in that line goes to the bottom of the carby the next one from the top of the carby to the primer then from the primer back to the tank.

if it runs on choke only and it sat up for two or three months the carb diaphragm may be brittle and not pumping fuel. install a carb diaphragm and gasket kit or try opening the high speed jet a 1/4 turn

Have you removed the carb. and tried to clean it? If not, get the numbers off the carb. and pick up a repair kit for it. Dismantle it, clean all orifices, remove the low and high speed needles (may only have one and count number of turns each one is at by screwing in until lightly seated then remove ) and clean passages with carb. cleaner. Reassemble, install, adjust initially with original settings and start. Adjust from here. Little carbs. are very "touchy" when adjusting.
