I'm spitting oil out of my muffler. Same exact mix I use on my echo blower with zero issues on any other equipment but my PAS225. But the 225 has been spitting oil since day one. Even first year I was using canned mix 50:1.
It does work the screen get all carboned up, and then the trimmer starts to bog ,their is a plug under the primer ball if you pull that you can also adjust the carburator.
Hey Zippy that’s the baffle w/spark arrester screen. In some states it’s illegal to remove the screen other than to clean it. After cleaning it must be reinstalled. The real killer is the muffler. Over time the muffler gets clogged with unburned oil causing increased back pressure to the engine. Remove the muffler from the engine and soak it in a carburetor cleaner like B12 Chemtool for a few hours. Drain the muffler then reinstall on the engine. The muffler is now within the restrictive specs and the engine should run fine.
Stalker billet muffler on daves discount motors, it can be fit to any echo model. Ive been building gopeds mini bikes etc for years . Your chances of starting a fire without a screen is slim to none . Dont be dumb .
Most of the time, if someone is having issues with their spark arrestor screen fouling out badly, it is either because they are running too much oil in their mix (like Echo used to recommend years ago), or because they are using cheap oil. I never have any issues with any of my screens nor do I have to clean them, ( I check them a few times throughout the season, but they are always clean), and I run either stihl HP Ultra, or Amsoil full synthetic.
It seems to me, Echo used to recommend running rich and then mentioning if you do run rich, to peg the throttle for about 15 seconds at the end of each use to help clean the spark arrestor screen out. I remember doing this with my earlier Echo power equipment and never having a problem. I've always run them rich and use their oil just because its readily available local to me.
I only have issues with my 225 spitting oil out of muffler. My echo hand blower and backpack blower and my echo chainsaw run fine with no spitting. Using red armor echo oil. Same mix. Lol even tried tru fuel in case I was mixing wrong. Nope. Only that machine spits oil
Even though the wires used to make that screen are very thin, they still act as a restriction across that relatively small exhaust opening. To get a rough idea of how much the screen effectively reduces the size of the opening, imagine taking it apart and laying all the wires flat, side-by-side with no space in-between them and you'll see how much it reduces the size of the port. Nothing really wrong with doing this as long as you won't be using the machine in an area where a tiny spark could start a brush fire...
@@gtowncasey111 no. They make power off of back pressure. An expansion chamber is completely open, shine a light in, i am 100% accurate. If you choke up a two stroke with baffles, catalysts, and other unnecessary bs, you are literally taking power away. Two strokes like exhaust flow, but with back pressure.
@@midwestsirens the same EPA that's said ethanol was good to put in gas? Well I don't know how to adjust it so I'm leaving it alone. They do allow idle screw to be adjusted now and even have a part of manual that instructs you
Does it have more power? I just found three mini manifolds cover the scream of my echo 225. It was a quarter sized slot overlaying one about a quarter sized rounded. Then the screen underneath. Very restricted. While the screen was clean after years of heavy use the inside has a lot of carbon build up.
Are you talking about removing the baffles from the inside of the muffler for more power? It for sure will be louder, but I have no idea what it would do to power.
Yeah, they get blocked fast when your using it a lot. And gives it a little bit better flow. I noticed a bit on mine and no like most people think it will not start a fire. Thats not the purpose of that screen.
Sounds like a coil pack issue, mine did that on one of my older weedeaters and i changed it and it worked fine. I used the ebay one and worked for yrs.
Bob my 26 years in the fire service says you are correct concerning the Spark Arrester Screen. Check your county or State’s Fire Marshall’s Office for approval to remove it permanently.
