Echo SRM230 cant get head off - Echo Rapid Loader, Trimmer Head

remove your spark plug and try to pull over. if it still won't turn over then you will have to decarbon your head or you have vapor lock so then with plug removed pull recoil and if fuel sprays out of plug hole keep pulling over until there is no more spray from hole. clean plug off. reinstall and try starting

no but parts tree dot com does...

Check the spark arrester in the muffler out let is no blocked with carbon, remove the muffler and check the exhaust port itself is not carboned up.

Please see page 14 of the following manual for detailed instructions (including tools to use) in order to accomplish this procedure. You see, you have to lock up the gear drive so you can get the head back on the threaded end of the driveshaft.

set air gap to 0.010" to 0.012" should be good

cheers

If the engine has locked up, it is usually due to either overheating, or lack of lubrication. The SRM series of trimmers requires a 40:1 fuel mix. If you were not using 3.5 ounces of 2 cycle oil per gallon of fuel, then most likely the engine locked up due to a lack of lubrication. To determine the cause, remove the muffler from the engine and visually inspect the cylinder. If there is scoring and scratches on the muffler side, then it has overheated. If the scoring is on the carb side, then it is a lack of lubrication. Overheating is usually caused by a lean condition. That means too much air, and not enough fuel in the cylinder. A lean condition is frequently caused by the carb being out of adjustment. Most manufacturers recommend to rebuild/overhaul the carb every 50 hours for low level units and every 125 hours for mid-level units and every 300 hours for commercial units. The SRM230 would be considered a mid-level unit. See the emissions label on your unit to confirm. Echo is a very good quality manufacturer. In my shop, I perform maintenance on many Echo units. I typically recommend a tune up to my customers every other year. I hope this has been helpful.

Check out the manual (available under the technical documents section of the Echo webpage, or at http://www.echo-usa.com/documentation.asp?Model=SRM-210&lang=E )and it will tell you how to change it.

line up the hole on the collar that the trimmer head is installed against with the arrow or notch on the gear housing, insert a punch or the brass colored pin that most Echo pieces of equipment come included with, this will lock the head. now turn the head clock wise, IT IS LEFT HAND THREADED! so righty loosey lefty tightey. now install the rapid loader with the included washers and10mm gold colored lefthand thread nut

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.

try uninstalling sound drivers and reinstalling them (or newer)
