SOURCE: How do I adjust needle valves on a 25cc Homelite

Set the lowend & highend needles to about 1 3/4 to 2 turns each. Choke the carb or prime it, until the carb is wet. Fire up the engine and let it warm up. Let's set the topend first since it's the easier of the two. Go to full throttle. Adjust the topend needle for peak RPM. Leave it wide open for about a minute to see if it changes any. Should the engine go lean, open the lowend needle slightly, if this dosen't work... you will have to adjust the needle valve inside the carb.( I will explain this later) If the topend runs OK, then slowly pull the throttle down until the engine begins to "four cycle" hold the throttle there. Adjust the lowend needle until the "four cycling" barely stops. Now lower the throttle more until it "four cycles" again, and adjust the lowend again. Keep doing this until you reach full idle. Now, from full idle begin to throttle up until the engine starts to bog or hesitate. Open up the lowend needle just enough to eliminate the bog or hesitation.

SOURCE: PRIMER BULB WONT PRIME

I would recheck the carburetor to make sure you put the diaphragms next to the carburetor and not the gaskets.
Please if it is not priming you may have the fuel lines hooked up wrong. Also check the fuel cap to make sure the vent assembly is there. If the tank is not venting, the tank will get a vacuum in it not allowing fuel to flow.

Good Day.

The bulb repair kit can be purchased a home depot or lowes, or whatever is close to your home. These can be replaced fairly easy. It is usually prongs on the backside that hold the bulb in. After pressing these the bulb will come out of the housing and disconnect the tubing from the bulb. It a good idea to replace tubing when doing this, the tubing is rotted or dried out and eventually cracks. Keep in mind where the tubing goes. One will feed from the gas tank and the other will feed the carb.
