Hey everyone, newcomer to the forums. Seeing some very knowledgeable info around the site, and thought it's time to get involved.
I'm working on some old commercial Echo brushcutters of a few model flavors. They are in need of the basics to begin with - fuel lines replacement kits, carb gasket rebuild kit, replace rotted-out primer bulbs, air filters. PartsTree seems to be a good source for OEM replacement stuff. What really freaked me out (until I realized why) was the seemingly ridiculous cost of a muffler. They actually have a mini catalytic converter in them. EPA won't leave us alone. I'm going to reuse old ones at that price. Don't suppose these any benefit to gutting them?
Also may need lube for the gear head, maybe bearings (?). That should do for most of them. Here's the models I'm working on.
2 SRM-400U's s/n 03003009 and 03003032
1 SRM-400 s/n 03003212
2 SRM-3800's s/n 005819 and 007726
2 of them run from a redneck quick cleanup. I'm amazed at how well the cylinders on these commercial units held up. Hard chromed bores survived in almost pristine condition. Night and day from garbage Ryobi Home Depot junk with plain bearings and raw aluminum cylinders, crap carbs.
In regard to replacing fuel lines and the grommet, I see "kits" that come with yellow (Tygon hopefully?...) and unknown material black fuel lines. I would like to use strictly Tygon yellow for all of them. Mostly for being able to see fuel flow, and durability. Is there a size difference between the 3 lines and fittings for these machines?
Sorry if I've rambled a bit, but I do enjoy making these things hum again, and these Echos are some of the best-built and hardy little beasts I've ever wrenched on.
