Where is the fuel leaking out at the carb, or the lines coming out of the tank.If it's the carb.,there is some debris between the needle and the seat,carb needs to be taken apart and clean,if the fuel lines in the tank replace the lines.Also check the spark arrester screen in the muffler,may be clog.Hope this helps.

Funny! I just went thru the same thing with my Echo trimmer. Posted a long scenario over on a different forum that I cannot post here about it. Best part of it was, I forgot about the ON/OFF switch over the winter. Started first pull after I re-discovered that!

Try priming the carb with a few drops of gasoline. It should start momentarily. If it does then you aren't getting gas through the carb for some reason. Try a different spark plug too. Just because you see spark doesn't mean the plug fires under compression. The muffler outlet could have a mud daubber nest in it. (very common)

What happened Brad?

still cant get it started...put a new plug..............tried too put gas in carb...nothing...cleaned needle and seat area...........no nest......screen is clear enough and it seems to have decent compression................??

I ran in the house and wrote a long dialogue about the incident! It was so funny, I just had to tell ALL my friends about my ineptness. BOTH of them laughed at my absentmindedness. One even suggested that I install idiot lights, just to make sure it never happened again.

That being said, once I got the little beast up and running, I trimmed my lawn. It worked just like it was supposed to.

any tips?? i finally got started the trimmer...but only at full throttle and choke open.........when i let go she stalls.....thx

Do you see bubbles in the fuel lines when running? If so, cracked fuel line. If not, just take apart the carb, clean it up a bit, and put back together. Might have some oil residue clogging things up a bit in there.

Let us know...

brad....no bubbles in line....just paid $28 bucks for a cleaning....same prob....only runs at full throttle , choke open...could it be needle and seat ?....diaphrams ? (i replaced the diaphrams last year) ....wierd! and frustrating

could it be a bad crankcase gasket leaking

Good point. Check all connections/nuts/bolts, make sure you don't have a loose cylinder or carb. Bottom line, not getting enough fuel. How about a clogged muffler? That would not let exhaust out, in turn no fuel/air mixture in?

i will check..

Check to make sure the exhaust port is clear. Remove the muffler and take a look. If you cant see the piston there is the problem. Pull the spark plug. Then gently cycle the engine with the pull starter to rotate the piston to bottom dead center. Use a popsicle stick, so that you dont gouge the piston, rings or cylinder and scrape out the charcoal. Blow the remainder of the dust out when your done with compressed air.

Best wishes,

Don't forget to check the spark arrestor screen (if it has one) inside the muffler. Mine kept clogging up every year so I just removed it and no problems for the past 3 years.

bob...the port is clean...as a matter a fact the piston is clean as a whisle for its age..........

Hey,
I am having a similar issue with my GTR-200 Curved Shaft Trimmer only it idles fine and stalls when I increase Throttle. I have taken the following corrective actions:
1. Replaced Spark Plug, Fuel Filter(and lines)as well as the air filter
2. Had a shop replace the entire Carburator module
3. Cleaned the exhaust screen

I have had no problems for 4 years and the trimmer is effectively useless right now with the stalling. Any ideas?
