I, too, was curious about the air filter cover and the baffle in front of the carb, so today I tried modding them. Bear in mind that my 355t has the plastic mesh air filter, not the older style flocked air filter. That may make a difference. I had already opened up the muffler, removed the limiters, and advanced the timing 0.020". For today's tests I started out by tuning the H screw for 13,800 - 13,900 rpm WOT. Then after each mod, I checked to see if the WOT rpm had changed. After enlarging the filter cover opening, WOT was 13,900, give or take 100. No obvious improvement. I think most of the air enters the cover from the boot that connects to the flywheel air, so the stock cover opening is adequate. In hindsight, I would not bother enlarging the filter cover opening. With enlarged cover opening + remove carb baffle, WOT was still 13,900, give or take 100. Then I reinstalled the carb baffle but with the lip removed from the top of the baffle. WOT was still 13,900. In hindsight, I would not bother removing or modding the carb baffle. I believe the baffle exists to prevent backflow from wetting the air filter, and that's probably a good thing. Then I tried removing the mesh air filter, but with the cover & baffle in place. WOT increased noticeably, hitting the limiter on the coil at 14,500+. The mesh air filter seems to be a big restriction. Removing the air filter was only a short test for the sake of science, and no one should actually cut wood without an air filter -- though I would be interested in a comparison of the mesh vs. the old flocked filter. Unfortunately, I don't think the two types of air filters interchange without also changing all the plastic parts on the intake. Then I reinstalled the mesh air filter, but sprayed it lightly with cooking oil (Pam type product). The saw would not start with the oiled filter! I had to remove the air filter to get it to start, let the saw run for a while to clean it out, re-install a clean filter, let it run for a while, and retune the carb because it still seemed to be running a little rich. The 355t is definitely very sensitive to the condition of the air filter. My conclusions and recommendations: yes to a muffler mod and retuning the carb, but otherwise the major restriction is the mesh air filter. Keep the air filter clean and if necessary, carry spare filters and swap them in the field, because it doesn't take much dust on the filter to restrict flow. Do not oil the air filter. :-)
@timl.9990 "removing the baffles and opening up the exhaust." When you make 2 changes at once you don't know which change did what. I ensured that the fuel lines were not squeezed. The mesh air filter plugs up quickly -- it doesn't look plugged up but even a little bit of dust on the filter restricts flow as evidenced by lower WOT. The mesh also lets fine dust enter the engine and coat the piston and ring with sawdust gunk. I use my 335 hard when doing trail maintenance, sometimes running 10 hours a day several days in a row. I had to re-ring when the saw was only 2 weeks old due to that problem. I have since bought spare air filters and plan to swap air filters at least once a day, but there will remain the problem of the mesh letting dust pass.
Excellent video mate, I've always loved my 355t, have two of them now, one still NIB. The one I use has been used almost daily for 3 years and the cylinder and piston still look beautiful, only thing I've had to replace is the oiler. Prayers from Maine for you and your family, be well brother.
I did these mods. Took about 45 minutes. Put a slightly smaller hole in cover plate. Runs great. I only had to adjust idle after completion. The idle was too high after mod. I didn’t feel it needed carb adjust. Used clippers to nibble those air box cover teeth. Filed smooth.
Well, when you open up the intake and exhaust, it's able to breathe better, which without also adjusting the carburetor to match, it's going to run more lean. Thus it's similar to the same effect of running out of fuel, which causes the rpm to increase. Instead of adjusting the idle, you should have enriched the carburetor by turning the needles counter clockwise. You must match the amount of fuel with the increased amount of air. This increases the power. Running lean basically strangles it and also prevents proper lubrication.
Thanks for the video! Greetings from Russia, Kursk! I 've been watching you for a long time , I really like your videos ! There is a lot of information on the Internet about sharpening a chainsaw chain at an angle of 45 degrees for hardwood. That the chainsaw saws faster and better than at an angle of 30 degrees . You can conduct such an experiment. Compare the chains with a sharpening angle of 30 degrees, 35 degrees, 40 degrees and 45 degrees. It would be very interesting to see the results .
I had to put a leash on mine. every time i start it it just takes off now. Porting would make a difference as well but the saw is night and day just with those easy mods. Hard to see in a video but people that wwee at smittys saw that first hand. Helpful video as always
Very good little saw. They cut good for a 38cc saw. I own one. Keep a saw sharp and they cut good. Very reliable. I have a ported ms 250. Runs way better. But gotta wear ear plugs everytime I start the saw. Just opened the baffle up and bent fins open. After I ported the cylinder. Nice to have power but nice to have a saw that doesn't make you def in the future. Toss up.
Just noticed the muffler on the ones over there are different, mine has a smaller hole at the top and a bigger hole at the bottom but not a big slot like that one. Also did have a cat which I removed, also noticed on a forum the usa ones seems to have a windowed piston. Mine doesn't it just has two small cut outs that match the primary transfers, I've ported it now though hopefully gonna resemble over weekend, nice vid hopper 👍
My 355t has a mid range stumble I can't get rid of, stumbles going up, and hitches going down. By hitch I mean gets stuck at mid for a moment as if its lean in the mid range. My saw has the limiter caps removed, that intake thing you pulled first, and I matched the muffler opening to the exhaust port, as well as rounding the openings to the there isn't a 90 transition from exhaust port to muffler. I haven't yet expanded the muffle exit yet. Airbox is still stock.
I spend a little more time on those Echo muffkins than you do . I pry that deflector off and take the bottom one off and just use the outer one then I open up the outlet on the plate with that magic material removal device and bring the opening to the bottom of the defector . Find tune the chain , rebuild the carb it - ta be fine .
I cant start ported P-81. I just finished a first cut in a 30” log with a 29” bar. I set the saw down, it was idling when I went to roll the log to finish the cut, the saw coughed and died and ain’t never started since. Im good with a Zama , and I have spark. Im really bummed, I absolutely love this little wasp.
You had me at hillbilly. I'm a city rat with a garage and a backyard. Got some trees I need to knock down. Why the Oregon? And what chain? Really appreciative your video. Thank you. I'd love a CS-400. Redoing all the flooring. got my Echo 16" CS-310-16. You rock brutha!
Yep I saw what you did on that other channel . I've got two of those little Echo climbing saws but I can't remember what numbers they are ( one orange one gray ) , one I've already restore and had to replace the carb boot on that one and the other I got a month ago at a auction and just thowed it down on the floor in the shop because it's to hot here on the Gulf Coast of Texas to be working on saws BUT I'm gonna check that air cleaner mod thang out on them . I did do the air cleaner mod on my Stihl 271 and I even did more than you do to the air cleaner mount on the 271 and it made a big difference with the muffkin mod I did to it . Where did you get those extra long bits you use there in that driver and how long are they .
The difference in "cut - time" was more from just messing around with the Hi jet, to be fair, have both modified and stock versions running at the same rpm's...
Thank you!! I did the air filter modz from your last video, already had the limiters and muffler mod. And wow that made a huge difference. Can’t believe manual shows max 14.5k 3k L, I went up to 13.8k H and felt the idle hang more and brought it down to 13.5k H and at 3k L. 355t’s are great saws. Also have pull black air filter diverter’s off 590’s and 620’s and made a difference just the carb split back seams to clog filter faster. What spray did you use to clean?
12:57 I love performance but if I do this to my top handle saw there is 1 major downside, I run an old McCullough mac130 so doing stuff like this to a beautiful piece of history is just barbaric, in my opinion it’s doing damage so that’s why I don’t do anything to my mac130 😅

I'm going on 2years with mine and it's still going strong. I feel like people overlook the ol 355
I just picked up one last week, still in box. I what to do the muffler mod and see how it works. Stay safe cutting. God bless.

I hope everything is ok after that power outage. Prayers
Excellent tips, sometimes easy is the best way to go! Cheers!

Great video! Such an easy mod. I finally get to use my step drill bit that’s been sitting in my tool drawer for years 😅.
Many prayers for ya'll hopper, thanks for the airbox mods.

My 355T comes off high rpm late as well. It won’t tune out. Figured it was the way it’s built. I bought mine new.

After the exhaust mod, the Highs is the only thing that is needed to adjust? And not the carb?
Most times just alittle adjustment on the high jet is all thats needed somtimes all need alittle tweaking to get it perfecto
Great vid 1/4 pitch for me tho. Cheers
