SOURCE: engine starts finem, but will not reach fill RPM.

Check the fuel lines for cracks/breaks. If they are o.k., then:

You will need to disassemble the carburetor and spray with carb.cleaner. Make sure the small screen is free of debris.(Should be able to see daylight through it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance, just let me know.

Smoke generally means you have too much oil to fuel ratio in your mix. Mix per manufacturer 50/1 exactly and try again.

Have a ECHO gas trimmer SRM 2100 wont start. coulld it be the fly wheel


If it doesn't turn over when you pull the rope it could be in the starter assembly or the flywheel where the starter pawls engage it. If it turns over then you need to check for fuel, spark, air and compression.

ECHO SRM 2100 GRASS TRIMMER HAS NO POWER


For all others with String trimmers, blowers and other 2 stroke style engines...
If no power on high, tends to bog, won't run once choke off, check these:
  • Fuel Filter - It's IN the Gas tank; Just replace it
  • Spark Arrestor at Muffler, it's a screen that tends to clog up and causes very restricted exhaust flow
  • Spark Plug - again just replace it
  • Carburetor, clean or install rebuild kit
  • And adjust sorta hidden High/Low carburetor adjustment screws
Take a look here...

And here:

ECHO SRM 2100 GRASS TRIMMER HAS NO POWER


Carburetor is probably gummed up inside. There are very fine needle-thin holes in the spray nozzel through which gas has to flow. if they are gummed up, you will have an engine that starts, but has no power. try to take the brass nozzel out of the bottom of the carburetor, it unscrews & may be kinda tight. but take it out & clean the smallest holes with a thin piece of wire. should work great after that.
