GT2000 String Trimmer Issue after replacing Primer Bulb, Lines etc

9 years ago

I have an older GT2000 echo string trimmer. It was getting messy leaking gas from the
rubber stopper thing that the gas line went thru into the gas tank. I bought a kit to replace the lines, rubber
thing, primer bulb and washer in the gas cap. I installed it. It seemed pretty
straight forward. After reassembly it would not start. At first I thought the
choke did not seem to go up as far..I am still not sure if that is an issue but
it looks right. Anyway, I removed the gas lines and sprayed some carb cleaner
in the inlets then popped the gas lines back on. It started right up, I used it
for a half hour or so. I did mess around with the little screws..it seemed to
run a little rough until I did so. A few
weeks later (I only use the every 3 weeks or so) I pull it out….won’t
start. I pop off the gas lines, spray
some carb cleaner…starts right up…works fine.
A few weeks later…this past Wed…won’t start. Again with the carb cleaner…again it works.

Any idea what the problem might be, I only use it
infrequently but the removal of the lines is getting old…and I’m almost out of
carb cleaner!

is the primer bulb filling with gas when pressed? by the parts diagram it shouldn't have a choke? if its a little plastic flap it should cover the inlet. when people are having fuel issues i usually recommend replacing the carb. also you can pull the air filter cover and shoot starter fluid in the carb that way.

Yes the bulb fills..and nothing leaks anymore. I can tell you there is an organge slider..I always slide it all the way to start then back it off as it warms up. It ran fine before the part swap - just leaked. It runs fine now...albeit only after shooting carb fluid in ...lol...

i've messed with a few little echo units (blowers, weed eaters) and the easiest, no stress solution is to order a new carb. if your weedeater is 1 of the gray echo's you got a lot out of the original carb. check online, you should be able pick 1 up for under 30.00.

hi, are you comfortable taking the off the carb? it consists of fuel lines, throttle cable and 2 screws. there are letters and #'s on 1 side and #'s on the back. looking up your model weedeater it calls for "walbro" c1u k52. i've had good luck with the knock offs.

funny you should mention taking off the card. I did so. I also noticed once I removed the two screws the choke suddenly moved more freely. It did not take me long to determine that when I put the filter back on and tightened it up, I must have over tightened it because the screw was now prohibiting the choke from opening all the way for stating...it was hitting the screw. Not sure why this never happened before in all the years I have had the Echo...I did buy 3rd party air cleaners last year...maybe they are somehow thinner and allow the bolt to tighten just enough more to block the choke. It seems to work now. I will try it again tomorrow jut to be sure. If I am wrong, then I'll buy the new carb. Thanks!!!

you've got to make sure you put the screws back in the same side they came off. 1 has a spacer/washer that allows the choke arm to move freely.

I never had the 2 bolts out before...it's the single bolt with wing that holds the air filter...tighten too much and the choke won't open...

glad to hear it. there's not much to the air filter, i don't think after market filters are going to be that much different if any. that little wing nut just holds the cover in place, no need to over tighten. happy weed whacking.
