Echo SRM 225 Weed Trimmer Won't Start - Why?

Learn how to diagnose an Echo SRM 225 that won't start possibly due to bad crank seals or leaky exhaust gaskets without special tools. This problem is common for many a 2-stroke trimmer, garden tool, chain saw, strimmer or blower made by Echo, Stihl, Husqvarna, Shindaiwa, Ryobi, and many others. This tutorial can help you to understand why your 2-stroke trimmer or blower is difficult to start or won't stay running. Sometimes a clogged muffler or spark arrester screen will alter the ratio of fuel/air flow on your 2T machine.

Wear your safety glasses, or you'll put your eye out. Try on some gloves. Take off that spark plug boot. Clean your room. Open the windows, those fumes are nasty. Just 'cause I do it, don't think it's the end all, be all solution. There's plenty more ideas out there, I can't take responsibility if you slice off a few fingers after watching my videos. And don't just pour that toxic stuff down the sewer or in the ditch, dispose of waste responsibly. Just be safe, OK?
