I need some help if anyone can assist.

I have a 1 year old Echo SRM-230 Weed Eater that has worked well the last year on residential tasks (my yard). 2 weeks ago the 230 (Ill call the weed eater this from now on) would start fine and idle but the second I engage the throttle the 230 dies. I am pretty handy so I will lay out what I did next:

1) Thought my fuel mixture was to rich since it idled with no problem so I remixed the fuel and filled the 230 up. Same result.

2) Pulled the carburetor off and cleaned with B-12 Chemtool. I made sure no gaskets came in contact with the B-12. Reassembled the carb and same result.

3) Pulled the carb again, drilled the plastic cap on the base of the carb to access the jet on the base of the carb. Clean the jet (not clogged that I could tell) and let everything but the grommets and gaskets soak in the B-12. Assembled and same result.

4) Bought the Echo filter, spark plug, and fuel filter kit from Home Depot. Pulled the fuel line and primer line. I flushed both line and no obstruction were present that I could tell when flushing the lines. I knew it wasn't the air filter (though dirty) because I cranks the 230 when I removed the air filter (I installed the new air filter). Spark plug look clean still (I cleaned and saved the used one and installed the new spark plug). The fuel filter was obviously stained from the fuel mixture but I tossed the old one and installed the new one. Probably should've saved the old one but I already tossed it out of frustration. Cranked the 230, started and idled no problem. Engage the throttle and dies.

5) Went back to Home Depot and bought TruFuel 50:1. Drained the tank of the new mix. Started the 230 to burn old fuel (I realize this is bad for the engine but I was frustrated and just wanted the old fuel gone). I put the Trufuel in and cranked the 230. No problem starting after priming but the second I engage the throttle it died again.

6) Pulled the carb again thinking there was a corrupt gasket when air was leaking in. Pulled re-cleaned and all gaskets are in perfect or near perfect condition. Re-assembled the carb. Start up no problem and idle. Engage the throttle and it dies.

I have exhausted my efforts. Anyone have any idea where I am going wrong?


*Just realized I posted in wrong area. Ill try and relocate

 

Adjusted the high speed jet yet?
Most require a special screw driver.
Could be one at least 5 different types of heads.

 

I have read about I high speed jet but the only screw connection I found I had to drill out the plastic cap to get to. I will take apart and photograph the carb. I may be missing where it is specifically located.
