If this is a solid state ignition ( black box mounted right next to the fly wheel)check for rust on fly wheel and coil/ignition.Sand with light grit sand paper if nessesary. Make sure to reistall with the same gap between the two parts.note the gap at this point could also be wrong.Also check to see if the clip inside the boot where the spark plug conects is not bent and that it is conecting properly. If this is a points ignition system then its basicaly the same steps.Clean contact pionts check plug boot for good contact. Or could be bad coil.Be sure you are using a plug with the propor heat range.
SOURCE: How can I remove Echo 230 SRM trimmer head?
Remove the top off the string housing and remove the nut in the center.
Replace the top, as if you have finished loading string, Lock it in place as you normally do and the turn the entire housing pulling up at the same time. Spring and the white mechanism will pop out and then all you have to do is lift the string housing base off the trimmer head. Note it will take you a few tries but once it comes off you will see how easy it is to remove. I was amazed. Got my info from a sales person at Home Depot.
SOURCE: What is the correct ratio for fuel mix for a ECHO
A 50:1 ratio with 89 Octane fuel can be used in all ECHO 2-stroke
equipment, provided the oil is ISO-L-EGD and JASO M345 FC/FD
certified. ISO-L-EGD and JASO M345 FC/FD oil must be used
with a mid-grade (89 octane) or premium gasoline in all 1997 and newer engines.
A
50:1 Ratio = 1 US Gal. 89 Octane + 2.6 fl. oz. ECHO POWER BLEND OIL
Echo Power Blend Universal 2-Stroke Oil can be used in all of our
2-cycle air-cooled equipment ever made. You may also use this oil in any other
brand of 2-cycle air cooled equipment, but it should always be mixed at the
50:1 ratio whether or not it was a 32:1 or 16:1 etc. machine. This oil is the
highest quality 2-cycle oil on the market today. There is no need to have
more than 1 tank of fuel for your 2-cycle equipment any more.
Use only fresh gasoline with a
minimum octane rating of 89 through 93 (mid-grade to premium) at all times. The
gasoline suppliers blend mid-grade and premium gasoline with greater amounts of
detergents and anti-oxidizing additives to keep the engines clean. Lack of
these detergents and additives in a 2-stroke engine will cause a heavy build-up
of varnish and gum deposits on the piston surface and ring grooves. Regular
unleaded 87 octane or lower gasoline may not contain enough of the detergent
additives that are needed in a 2-stroke engine to keep varnish, gum, and tar
deposits from forming. Use of 87 octane fuel may shorten the life of the
engine.
ALL TWO-STROKE OILS ARE NOT EQUAL!
ECHO POWER BLEND OIL, is manufactured exclusively for ECHO, Inc. and
meets the (ISO) International Standards Organizations highest performance rating of ISO-L-EGD for Air
Cooled 2 Stroke oils and is JASO
M345 FC/FD REGISTERED. Years of research and testing have resulted in an oil that is fully compatible with
fuels containing 10% ethanol and can be used in all air - cooled, outdoor power
equipment 2-Stroke engines at 50:1 ratio. ISO-L-EGD and JASO M345 FC/FD rated
oils must be used with a mid-grade (89 octane) or premium
gasoline in all 1997 and newer engines. Always look for the JASO M345 FC/FD square
logo and registration number to ensure you are using the highest quality
2-stroke oil for your ECHO product.
ECHO POWER
BLEND OIL is made for high revving, (7,000 RPM and up) air-cooled
2-stroke engines that are E.P.A. and C.A.R.B. emissions certified. Make sure
the oil has a EGD and FC/FD certification. Oils that meet ISO, EGA/EGB/EGC
and JASO FA and FB are of lesser quality, designed for applications such as
water-cooled boat engines, low RPM lawnmower engines, or snowmobile engines and
should not be used in ECHO Engines. Prior to 1997, oils were not manufactured
to these higher standards. Some or most of the oils were simply 30 or 40 weight
4-stroke engine oil with minimum amounts of additives. ECHO POWER BLEND OIL is the highest
quality 2-Stroke oil available and will provide maximum protection
against engine wear and carbon buildup.

It is ridiculous, there are a bunch of bolts, and then a multi-fit brochure showing a grid of nonsense.
There are instructions on the inside of the package, however that is how to string the line.
