Which piston did you use in this project ? Normal piston has 2 rings

What’s the max weight capacity and person capacity

Looks good work. When you file the flwheel key, you can easily measure the advance. Measure the circumference of the flywheel, then say its 360mm then 1mm is 1 degree. Your arithmetic will vary but the idea is the same. So make a mark at a fixed point of the flywheel against the casing with it rotated fully clockwise against the key. If you then make a mark 5mm (for 5 degrees) after that, then that is where you want it to rotate when you push it anti-clockwise against the filed key. If it doesn't go far enough, then file a bit more, If too far, then come back to the mark and tighten it down. Easy way to measure. Hope this helps.

Good work on the piston. Often a neglected area. Boy are some people negative! Those un-named aftermarket pistons are crazy cheap. I have always had good experience with the (genuine) Meteor brand which are well cast and the measurements are pretty true to oem. I find they're worth the small extra expense. Have you ever tried them?

That 024 runs beautifully for such a small cc saw. When I've ported mine it will be interesting to compare with my ported 261.

Thanks for sharing. Just about to port an early 024 like yours so that was really helpful. Good work!

shave 1/8th off of the intake skirt on the piston. it will start to pull air sooner and make longer intake timing

How did you get the quick connect gas cap to work? I just got an 044 and need new caps and would love to use those ones

wrist pins appeared to be different heights? you should get more compression off the original ?

👍🆙BC

Man, your stihl is running really nice. The echo didn't run too bad either - even for a little rich, especially with that chain. I'm getting older, and I seem to be grabbing a 50cc saw more and more for cutting, and looking at smaller wood to load. I've been running a little Dolmar 510 which I used to hate, all winter. As long as you can drop the wood high, like in the snow bank, and off the ground, and you don't need to bend over due to the short bar, it isn't too bad. It is heavy for a 50cc saw, but I must like it ok if I'm cutting with it - real smooth. I took off the epoxy limiters and no more cat muffler. It is open port, so I'm a little scared to do much porting it, and it has good grunt. But, heavy compared to your echo. I have an echo 490 too. Maybe I'll clean up the cyl. a bit on that. It runs real good with a muffler mod though. It has cut a lot of wood. nice vid!

Good vid.... I think I will build a 361 kit..... Do you think opening the venturi on the stock carb would make a good enough improvement for the big bore kit? I think I may grind it out.... Dyno joe did a similar mod on a G444 and it gained big

Does anyone know the stock timing numbers on these farmertec cylinders? Curious if the ex roof is high like the rest of them... Around 98?

Man that thing looks mangled

Because of the piston, you can raise the intake skirt .030 +/- .010.

I put a farmertec big bore on my OEM 361, port matched and polished the exhaust, ported the intake to a 461 boot and put a 461 carburetor on with a 660 impulse hose. I haven't put alot of use on it yet but if is snappy and screams.

You mentioned little longer or shorter stroke on 024. So I'm going to get a piston cylinder kit but how do I know which is which far as stroke so I know what kit to get? It's wood's boss avs far as I know. Thanks.

Air leak?? ive had my 026 die when idleing and found my leak at the tank ",I just picked up a 034 for 200 bucks basically brand new hoping to port it soon

Wow ur hands shake alot

Love me some 044 action.

Hope you noticed that the 360 seems to of had excessive amount of smoke coming off the chain?

Grinding looks good. Can I offer a suggestion for future builds?

Thems is some good numbers

Great work man👍🏻

with the pop up piston and base gasket delete are you anywhere close to hitting the piston at TDC?

Leave the bottom ring out

Nice, interested to see how she runs...... Was thinking of doing a full port job, muff mod, gasket delete with the bb kit..... That light saw with the spring antivibe at 64cc ported I think would be an animal..... Good power /weight

Also another note . Just the way my brain works but I feel like if you could get a piston without windows I feel like you would gain alot of velocity through the transfers . Just my opinion but seems right in the way my brain works

Pretty impressive save on that cylinder man

Nice light little toy ripper

I grind the lip that goes all-round split in half gut then weld or braze up lot easier then what you prolly just whent thru

Following this Brandon. I like how detailed your videos are👍🏻

My main concern with the performance increase of all saws is what are you doing to the dependability of the saw. This question never gets answered honestly, either no one knows for sure or they don't want to discuss this honestly.

Nice one.

Where did you buy the parts saws to work on?

That 361 is definitely pulling above its weight class. Nice video.

Hows the 4910 doing after the mods. Im thinking about picking one up.

Those are pretty impressive! I love those 4910s I want one so bad.

Looks like you did your homework , the port work looks great.I purchased a echo620pw to port but i am waiting on some tooling.Did you have a local machine shop cut the base ?

52mm just fits. 54mm hits. Hope you can get it working

Nice! That muffler sound quieter than a stock one hogged out

Fun stuff Brandon.... Did you try muriatic acid to remove the transfer from the Cyl? I knew that saw was gonna run for you. YOu did well on the port work. All fine tuning from here. Also I was that FT 36 ported too? I have an OE 36 to rebuild and port one of these days....

Nothing ventured nothing gained. Make sure the bevels are good and it should be fine. Curious to see how it runs

590 projects are always fun. Let me know if I can help with the hybrid project.

4910s are tough saws ported glad I cud help.you out

Looks like you’re a natural. Sounds like you’re well on your way to making a much stronger saw👍🏻

Glad I cud help can't wait to see it run

Great tips man..thx for sharing..just put one together n hogged out the lowers..after carb n tank vent issues it's running really good..think ill do the carb swap w a big bore soon ..have high hopes for this saw!!

Right on..man I'm glad I came upon your vid..lookin at 361 kit right now n just put hd14 in my 440..heard from several others only issue w 361 kits is carb..been tryin to find tillitson but since lookin at both carbs in gonna go your route w 44 swap..looks like it b great,did you have to swap choke butterfly rod also..is that only part besides top n bottom covers ..thanks for posting ..im in my 60cc portion of my addiction at the moment..lol. just ported oem 036 w heavy mods n has become my go to so b stoked to have a ripper 361 as well..how are they treating you..hope your well n thx again..

Cool vid. Appreciate you doing it. I've been doing 660 and 440 builds and performance mods. Not an expert porter either but sucessful. On the timing wheel thing, that is pretty easy to pic up.. You can google timing wheel and print one, glue it to some thin plastic or luan wood and put it on an old drill chuck. Once you do it it's not hard at all... I am here becuse just got 361 kits to build and they are certainly different than the 44 and 66... Especially those transfers, and their tiny... Did you consider rejetting the stock carb. That might be an easier option. I'm going to look up the jet size on the 361 and see if I have a needle drill to open that up a bit. I do it on the 660, although I do not believe the stock FT carbs on the 660 need it. I run the oem walbro carb as well, which has a bigger jet, and cannot see a difference in that or the stock FT jetting. Thanks for the vid, got me thinking. I have to figure out how I'm opening that muffler, that one piece deal looks like a PITA.
