I saw it on Ebay/Craigslist

[a. palmer jr.]

so, regarding the stack muffler. i have a C-5 that i am approaching the conclusion of a almost complete rebuild and am wondering if there's an alternate muffler that would be better suited.
i know the stack is loud but how does it rob power?

2 cycle engines actually suck air in from the intake and exhaust on the down stroke of the piston. You'll notice on the big motocross bikes and the hot saws they use an expansion chamber on the exhaust with the end of it not too big. They trap the unburned gasses in the chamber and bring it into the engine to be burned along with the intake fuel. It provides much more torque than having an open exhaust, which is what a stack is.
I don't know if you can fit a muffler on that saw or not but something like a big Super XL muffler would work better than the stack.

i can see what you're saying about the lack of back pressure. wondering if someone has ever installed a baffle in that little bitty muffler. not much room there. is there an AM muffler that is commonly used with the C series?

Jerry, the C series came with both stack and "can" style mufflers. I don't have a spare for ya, but perhaps someone else on here does. If you look back a few pages, you can see the can muffler I robbed off my C-91 to use on my XP1000. It's similar to, but smaller than the XP mufflers.

My 5 has the stack, maybe one day I'll do some swapping and see if there is much difference between the two in the wood.

If you examine a 'stack' from an XL-12 or C5 etc., the outlet area is about 60-70% of the port area.

I had one XL-101 that would not even start without a stack. Air diluted the incoming charge too much I think.

Yep. The can muffler used on the C-series and the XP1000 (and XP1100 IIRC) is a '2 screw' unit. The XP1020/XP1020A/1050/XP1130/1130G can is a larger 'three screw' muffler with a 'stablilizing' third screw that secures the can to a boss on the cylinder. This boss is lacking on the C-series and the earliest XP saws. I once modified an XL-900 series muffler to work on my C-5, but abandoned it because the modification made it too weak and it was shaking itself to pieces. I'd had to open up the mounting flange (C/XP series ex port is wider) and this weakened the can. Also, that XL-900 series muffler was designed with the third screw (like a later XP series muffler) for stability...........and mounting it on a C-series saw provided no support back there. That C-5 once again has the stack muffler (and now belongs to a friend). My remaining C-5's have stacks as well...

I have a C-Series can muffler for them, but it's missing the special studs that mount it to the cylinder. They thread into the cylinder and secure the muffler can.......................and also have internal threads on the other end to take the cover screws. I haven't procured these studs, and haven't taken the time to make up my own 'workup' of them using threaded rod, nuts, and lengths of steel tube (to support the cover at the right spot) yet. I'll do the work to put that can muffler on my C-5 someday.

It's a low priority for me, as I don't run the C-5's much anymore (probably just at GTG's from now on, where the stack mufflers are "cool"). When I was using a C-5 for firewood cutting in BLM land, I had that modified XL-900 series muffler on the saw (with spark screen) to comply with regulations. Now that my 'working stable' has grown (quite a bit), I don't see the C-5's going into the woods anytime soon. I also don't care about the slight power loss when running the stack (it's noticible, but just barely). I'll just grab the XP1020 or the 1050A instead.....

Some of you thought the gas-powered battery charger was nuts ....

.... so here's the gas-powered snow shovel!

.... so here's the gas-powered snow shovel!

How does that work?

 

[Toolslinger]

Just looks like the second stage from a 2 stage blower... Slide it along, and it'll kick anything that hits those vanes out the outlet chute... Can't say I'd want to run it, but I imagine it would work...

Yeah until it hits a good sized rock or broken off chunk of curb and lunches itself and your hands/wrists!

Good point, I'd use it before breakfast to prevent this......:msp_tongue:

Did you get that 125 yet?

Well you can hardly blame the machine for user error... :smile2:

He can and wiil. You're talking to a guy who blamed a tap for ruining his cylinder.

Not yet, i expect them around the 1st-4th.

These adds are laughable!!

Almost laughable.

I would propose, that said dimensionally challenged (90 inch diameter?) crazy person pay someone to cut down that tree.

This is an epicly worthless troll post, you know that right? Everybody on here has given me a hard time since im the new guy but they have been helpful and informative too.

Absolutely nothing you that you have pecked out about me on your keyboard has had any substance or value. Its ALL been negative and condescending.

This week im going to louisiana to volunteer my time and energy for storm cleanup, then im going to fix a members clutch cover here for free, then im going do yardwork for an elderly neighbor and then ill start my new public seevice job.

I may not have 1/10th of the saw wisdom that you have, in fact, since you have been so studiously stalking my every post, i DID kill a mini mac cylinder knowing that new ones cost about $10 and i have another one on the way.... But you know what?

I could kill 10 mini macs and probably still be more useful and positive to the world.

Nobody likes a manchild internet bully and you're not winning cyber cool points here.

Im not sure if youve noticed, but every time i called you out on your predatory schoolyard antics, you're friends have only been able to defend you by saying "thats just thomas, hes kind of retarded, different, an A-hole until you beg his friendship and he accepts, ect"

Not even your friends here can adequately excuse your actions.

On the streets this usually goes: ask, tell, force, jail.

I dont have those options here and i know it so i will just present the situation like so;

Please, pretty please, stop internet bullying me.... You can if you want, but youre not really hurting my feelings much and only make yourself look like a fool.

I lived in upstate for 10 years. I would not use any less than a 7hp gas shovel. I do miss the roof rake sometimes though.

Who said Thomas was 'kind of' retarded?:msp_confused:
