I also saw an impressive gain just cutting out the deflector plate in the muffler on an arm 225. Only problem now is it runs a bit rich. Used about 30% more gas than usual. But power definitely improved

Ok thank you. Didn't realize the cs-400 was such a handy saw

Thank you for the reply. But I think the 400 is bigger than I'm looking for

I currently have an echo cs590. It's a great saw and I love the thing. But it can be a bit much limbing downed trees and bucking up 12" and under wood. It's basically more saw than needed for this application and I'd like a lighter saw for these tasks. I cut about 15-20 face cord a year to feed...

That thing sounds awesome

No blades aren't stuck. They move a tiny bit. Once it's had a good five minutes to warm up it will rev enough to get the blades moving a bit

On this carb the jet I'm talking about it on the top of the carb where the primer bulb is but not quite under it right by where the fuel lines attach

Ok that was the hidden jet I was talking about. I didn't know that was adjustable though. So I just removed it, cleaned it, and I reseated it. You think I should try backing it out half a turn?

I forgot to mention I removed muffler. Exhaust port is fine as is apart arrestor screen. Even discovered it has a cat

When I replaced the jet in the carb I was unable to get the brass plug back in on top of it. I believe it's just for tamper proofing it. The gasket for the primer bulb goes on top of it. But I sprayed some gun oil all around the gasket especially where the jet it and pumped the primer but there...

It does start though. Just will not take throttle. I checked the fuel lines. No leaks in them

Hello all. I have an echo hc 152 a bought two years ago. Now I maybe use it for a couple hours total a year. A month ago I fired it and my echo grass trimmer up to just run them. Grass trimmer worked fine but hedge trimmer won't take throttle. Bogs down. Now with my low use of this equipment I...

Got my muffler mod finally done today. I didn't go too much. Just removed inside part of deflector plate and drilled 4x 1/4" holes around tube underneath the deflector. Not sure it made much difference besides it's a bit louder. Also tuned my saw for the first time. I'm now at about 1 1/2 turns...

True. Thanks for the advice. When I want loctite I just use blue as it comes apart easy but holds against vibration well

Thanks. I wouldn't use red though. I only use red when I don't plan on ever taking something apart. I'd use blue. But in this case I think I'll use anti seize so the bolts can easily come out. I'll keep an eye on them to see if they stay tight Now I just need to find someone with a dremel or...

Ok got them they were very dry inside. Maybe has to do with it being magnesium? I'll put anti seize on them when I put back in

OK. Those bottom two bolts don't feel like they should come out so I stopped. I can turn them but feels like they'll break if I keep going if that makes sense. It's not a tight like it's rusted feel. Just that it'll break

Hi. I've seen the videos and explanations for where to drill and cut and such but no one ever mentions how to remove the muffler in the first place. On the front you remove the small piece of steel to uncover the two screws. After taking those screws out what do you do? I took mine out and the...

Wow that was a long thread! Took me 4 days of casual going over to get here. I've got a 590. Nice machine. Running a bit lean on low adjustment need to bring into dealer. Stupid red plugs! Don't want to void my warranty if I don't have to. Picked up for $399 in Canada last January. About 4 tenks...
