Show off your muffler mods

Those 2260/562 mufflers sure are a pain to mod Kevin, did my 2260 recently with a drill and a big burr in it, took me about an hour and a half.

I hear you. I bet it took me that long also. I removed about 2 in of the midsection of the baffle is that was all I could get without cutting the muffler in half

Will you weld it back together Wilheim?

No, I recrimp these back close with a hammer!

OK. Thank you sir. Enjoy your Holiday!

Humble Dolmar PS-7310 SLR muffler mod.

The SLR muffler features a lot of surface under its spark screen.

Poulan 5200.

Poulan 5200.

Thought it might be. I have a 4200 here that I'm putting together, think it's the same chassis.

I have a spare case,fuel tank and maybe some small stuff if you have a need.

For my AM 660. Just did it today. Still needs woodstove paint. Had to test it...

My saw, which is fairly new, was running pretty fat as it was. (I bought it on ebay from a builder in B.C.) After burning about 1.5 gallons of mix, I leaned it out to get about 11,500 rpms (still 4-stroking at WOT) and left it there to play it safe. With the new exhaust, I didn't really need to fatten it up at all ... it still 4-strokes at WOT, though I didn't check what RPM I'm getting at WOT.

The fact that I didn't need to richen the H jet makes me wonder whether I should open up the exhaust even more...

Turn that saw out to 13,500 when warm, no load. You are leaving a bunch of power on the table.

Anyone got any quick tips for opening up the muffler on an echo 501p? @Miller Mod Saws, @Red97 can either of you guys give me the low down? A buddy of mine just bought one and after running my ported 350/346 and 261 he wants to pursue a louder saw. A little more power would be okay too.

Just wondering if I need to uncrimp the muffler and empty out the guts or if I can just take off that goofy cover and cut a big hole. Any help would be appreciated. Also, I just took a quick look, but it looks like a drywall screw will take care of the carb limiters. Am I missing anything there?

Easy muff if it’s like a 490 (cheaper sibling with plastic handlebar). Unscrew deflector screws and pull out the tube. It comes right out. Leaves a nice opening. You’ll see what to do to the deflector. I believe a drywall screw takes care of carb.
