Knocked the spark arrestor screen off the dual port muffler on my 440. Got a new one in yesterday. I was watching a Mastermind 461 build video and the same thing happened while they were doing test cuts so I know I am not the only one. I was wondering if more aggressive felling dogs would help keep this from happening again.
The problem is mostly with the screws. I had one drop off on me and I managed to find it and replace the screws. IIRC I used slightly larger screws for a better hold.
Those never come off my all orange saws LOL Thats a bummer that that happened . Looks like a cool saw thats done some work !
No shelf queens here. Bought it off CL a couple years ago. Outside wasn't great but it tested at 165 psi. I was wondering about the screws. Since it doesn't look like they pulled out. I paid more for the new one and it came with more stuff. Ie new gasket. And looks better built and better paint. We will see.
Id like to see full picks of your saw sometime ! Just looks like a tough saw ready for work. Probably is reliable too i bet
Smells like a good time to pull that can and open up the side port a bit as well as that narrow slot. Fatten up the high side after as necessary. If you drop in a new spark plug, get a reading after a few good cuts and tune for that tan/brown look.
If you aint forced to run them where you cut I remove them both. If I order new aftermarket I order the kind without them (customers decision every time). Last 2 on 440 and 046.
I pull them too. They create restriction. Ever put a fire screen in front of your fire then remove it and feel the difference in heat that comes through it.
Thought about pulling mine off the 359. I did put a non cat muffler on it, seems to run cooler now. Book says to pull & clean it frequently. maybe pull, , cut off the screen, no more cleaning needed
Should have done it. Insanely loaned the saw to someone and it came back like this. Didn't even last a week. I am gonna do a little something with one of them and see what I see.
Lol, Forage Farmer, you loaned out a dual port 440 mag? Seriously? Did you get a call from the Vatican requesting your co-operation? Somebody asks me to borrow a saw, they get an Earthquake 3814. That is, provided the pope calls. You wanna borrow a thousand dollar saw, plan on leaving a $1000 deposit. Don't have a G laying around you can afford to lose? Me either. Sorry, but I do have this Quake...
And a 28" ES light bar on it. Oh my gosh what was I doing? On the plus side I have a buyer if I ever want to sell it.
I was taught to never lend out anything you can't afford to lose. So most of the time I say, "that sounds like fun," & offer to help or quote a price for my help as appropriate. There are lots of places to rent equipment but if I don't think they know what they are doing I will generally try to help out.
