My homelite UT20002A won't stay running. I prime the pump and it will start and stay running for a few seconds, but then stops. The pump bulb is also dry at this point. I am suspecting a fuel flow issue somewhere, but don't know where to start. I am pretty handy, so i don't mind trying to fix it myself.

Re: home lite 20002a won't stay running
When you use the primer bulb does it pull fuel out of the tank and fill the carb and any extra returns to the tank ? I am sure this is the case since you can get it to start and then it runs out of fuel. It sounds like you may have a dirty filter in the tank or the diaphrams in the carb are stretched from age or dried out from sitting either way the first thing I would check / replace is the fuel filter and if this doesnot correct the problem i would then rebuild the carb. Good Luck i hope this helps you out

fuel issue, look for cracks or holes in the two lines from tank to prime bulb, check prime bulb, adjust/clean carburetor, may also need to check filter inside tank it is connected to the bigger of the two hoses. Tim
Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it run a few times like that and it will flush the gunk out of the jets, but most of the time you will need to rebuild the carburetor. If the mower is over a couple years old, then I also recommend that you buy and install a new carburetor repair kit, because the diaphragm will get hard and that will cause it to be hard to crank. When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position. That way when you go to put the jets back in, you know how many turns they were in/out. Please rate me, Thanks Good Luck, I hope this helped
Well if you are missing parts?...No. How could anyone from where we sit. But the fact that it starts with starting fluid is a great sign however. First off, Fresh gas/oil mix is A MUST! No getting around that. OK first, when you pull the throttle (Give 'er gas) does the little lever at the carburetor move back and forth at all? if yes, then what happens when you hit the primer bulb? Does it push/**** fuel from the tank? (My homelite spits fuel out to the ground when I prime the bulb, most spit it back to the fuel tank however) See if priming it moves fuel. You should see a trail of bubbles in the fuel tubing. You have to see if you are getting fuel at all first. Then does it maintain the prime? If not? Then the primer bulb will usually remain empty. A good prime should always show a half full or 100% full bulb at all times. Let me know what we got so far.
you either have one of two things wrong. my first guess is that you have a crack or hole in one of your fuel lines causing it to not get enough fuel. the reason it will run for a few seconds is that you pump a little fuel in when you prime it. my second guess is that you have a very plugged fuel filter or something obstructing the fuel lines. take a look at the lines all the way very closely for cracks, as this is very common in seasonal tools like these. let me know if this works. if not, i will help you get it fixed. thanks.
Check the muffler for obstructions. Remove the muffler and check the exhaust port sometimes they are near plugged. If so remove all the crud with the cylinder in up position to prevent getting carbon in cylinder. Trimm to adjust Turn both L and H set screws clockwise until they bottom the back each one out 1 and 1/4 turn. This should allow you to start the trimmer. Then rev to max rpm and adj. the H screw to max rpm. Then set the idle with the L screw with good idle without string head turning. Then when throttled it should do so without hesitation. Once this is set you may have to fine trim the H screw for max rpm again.
