Timing OEM and 3 different aftermarket 288xp cylinders.

[@larrybollinger7319]

Rabbit hole please. Always willing to learn anything your willing to teach. Thanks for all you do for us Tinman.

[@jetobey5656]

Your saw videos are by far the best and they are so "kind." By that I mean clear information that does not treat us as idiots, and at the same time you give us complex detail. I have spent 60 years on small block Chevys, learning something new on every engine. I am living that through you on 2 stroke saws, but not like I am in a lab--your lessons are clear and relaxed. Thanks, "Mike"

[@mattfleming86]

I bet 20 thou on that saw would be a "stout" starting saw. Heck I made a paper gasket for an 026 stihl, and it ended up at .019 and it would bite ya if you werent paying attention to what youre doing. Tinman.. thanks for making these videos. I'm comfortable with wrenching on saws. Been doing small engine work a long time. But I have yet to grind on one.. I started watching videos 7 or 8 months ago and I have learned a LOT from you. I appreciate your willingness to share and to teach. I have a couple Husky 51s to play with. Don't wanna touch my 'spensive saws. Yet. But between you, Charlie Brisco, the OPE forums, and a few other guys on youtube i'm just about comfortable enough to take that plunge. Thank you.

[@robertwoerner20]

Only 40 seconds into video and I'm glued in on this one. Been wanting to know this. Awesome content choice!

[@tinmanssaws]

Thats awesome!!

[@sagerman6779]

Outstanding. This is exactly what I want from a chainsaw chanel. I'm 55 and not only would this type of knowledge been out of reach, I wouldn't have even known of it's existence. Great job my friend and I'm looking forward to much more and watching that sub count rise exponentially. You've already picked up a head of steam so now just keep it up. Thank you my friend.

[@richnorman5017]

Great video showing the difference in timing on different cylinders Tinman!!!!! Can’t wait to go deeper down the rabbit hole!!!!👍🏻

[@aaronpowell4885]

Love the in depth videos. Thank you for putting the time, effort and resources into creating this awesome content and sharing it with us!

[@imperfectcuts7028]

Love a good rabbit hole video. Can't wait lol.

[@reliant_turbo]

Great video! I would love to see this video recreated with 372xp cylinders. That would be awesome.

[@Ceemysix]

Wouldn’t mind hearing more about blowdown. Great series!

[@eldoge3955]

Hey man love your vids. Just wanted to thank you because I started porting after watching your videos. Thank you

[@tinmanssaws]

You're welcome

[@NHLiveFreeOrDie]

Tinman, you should talk to Ryan at WCSS and see if you can do a video on Meteor, Hyway Tinanikel, Hyway Nikasil, NW and OEM cylinders for like a 372xp. Show the casting and squish band differences and the timing differences on like a regular 50mm cylinder. I bet that video would get tons of views, I know I'd love to see it. Keep up the great work brotha.

[@chrisfleming5109]

Hi from Scotland. I have a lot of chainsaws. Mostly husky from 80's cos I think they are best. I also have dolmar 116si and 120si and I think these are very best ever. I want to say your a very interesting person and your character has some excellent qualities. Your mother deserves a medal for how she brought you up in the early years. Have a good new year top man plus.

[@stevetheriault4164]

My buddy's had his 288 for 20 years atleast still runs great he used it to build his log house

[@old1234]

Love these kind of comparisons.

[@deeprice8321]

Love learning this stuff. So different than the v8's I worked on for so many years. Valve timing, lift, and duration was done with cam and gears. Wish I had gotten into chainsaws years ago.

[@tinmanssaws]

That's how I felt when I started 2 strokes vs harley engines. Cams and valvetrain did all the work.

[@fabzacres-blackcat]

Farmertec and Highway cylinders are not suitable for longevity imho. In order of preference: 1) OEM cylinder and OEM piston , best combo but most expensive- 2) OEM cylinder and Meteor piston , damn close to OEM - 3) Meteor cylinder and piston kit - I’ve used this combo on a few saws (266 to a 272 and a 268 to a 272) and the saws perform well and the cost is less than 1/2 OEM ….. Just my 2c , your mileage may vary

[@welshwarrior797]

Down the rabbit hole we go my friend😀

[@gyulatimko2075]

I love this video!! I learned a lot! I love to hear you to teach us about the short blow down-combastion chamber theme!

[@kuiperroerdink1670]

i enjoy the port timing talk!! also, i’d love to see the video about blowdown... very interesting

[@williambrehm401]

thank you very much for all your knowledge. I have learned so much from you.

[@Hboysoutdoors]

That was an awesome talk I love the info it really helps

[@Anthonywilkerson6963]

hey tinman i realy enjoy the vids been doing port work on banshee two stroke atvs and bikes for some time and getting more interested in saw powerheads i really like to see someone that takes the time to show people that are motivated to do these things and enjoy it great content keep them coming !!!!!!

[@zeromark202]

Awesome video!! Excellent explanation!!

[@billybobswood8153]

great comparison vid!! got a 52 mm and piston kit prolly farmertec for my 2163!! not really happy with the cyl and piston but just starting to port again! had to clean and chamfer all the ports and sharp edges and open things up a bit! learning again at 71 yrs old but it's fun! i built some real hotrod saws back in the 70's but it's been a couple yrs! haha Take er' easy!!

[@AaronTheViking250]

morning buddy hope you're doing well and happy New Year's as well. I am looking forward to seeing what you have in stores for us 😊.

[@tdawg8605]

Wonderful information, great explanation and comparisons between the different cylinder makes. Interesting about the deck height something I've never really thought of. It would be interesting to do the timing numbers on four or five of the same cylinders to see if there is consistency within the manufacturer or to emphasize the importance of identifying the timing numbers before modifying the cylinder. 288xp is a bit to much saw for what I cut. 55, 61 266, 268 and 272's are all in my world. As always best saw content video on youtube. TC Mahalo Tinman 🤙🤙🤙

[@Hillbillywoodrum]

Great video tinman keep up the great work freind.

Tinman Tks for the # on different cycle great video. 😊

[@hertugen.online]

Cool video Tim. I use PlastiGauge to check squish.

[@kennytheguitarfanatic054]

Would be interesting for you to do a video on the theory on short blow down.

[@fabzacres-blackcat]

Different blowdown numbers affect peak power at different Rpms … some saws are engineered for short blowdown (15-17) whilst others are designed for longer blowdown (23-26 or more) … Not really any theory to it imho , been proven out a loooooong time ago. With these chainsaw motors you really cannot make “one size fits all” statements and expect to be taken seriously as the design characteristics vary , also the shape of the exhaust port matters. I’ve been in a few of these “short blowdown” aficionados saws and let me tell ya for a fact : It was reversion - city with the exhaust leaving a trail into the transfers. This tells me there was insufficient blowdown at peak rpm. The cylinder tells a story

[@charlespeacock8360]

@@fabzacres-blackcat I'd be interested to know how much or little blowdown the newer strato saws prefer and how to achieve maximum fuel/exhaust flow without ruining the scavenge.

[@nateolmsted899]

OEM all the way

Thanks for doing this ! This is some super helpful stuff

Nice comparison Tinman, great information about all the jugs.. Happy new year to you and your beautiful family. 🙏✌️

[@scottfoster2487]

Great videos on the basics of saw principals. I wonder on a 288 if a 394 slug and jug would fit.

[@jmangus83]

Wonder how the newer hyway titanickel cylinders compare to the older one you tested here? And yes, please go down the rabbit hole. I'm new to saws and two strokes in general, so I love to soak up info when I can

[@afleetcommand]

Good stuff. :)

[@alessioG7176]

12:33 i read 99 not 101, thanks for your video

[@DavidArentz]

Hello Tinman, happy new year to you and your family. Last year you showed a makita. I think it may have been a 520i. I'm really looking forward to that build. Any plans for it. I've done two of the dolmar variants and keen to see your moves on a 52cc saw

[@marcuscicero9587]

do modifications to the cylinder, opening transfers and the exhaust port allow the saw to go past the recommended top rpm without damage?

[@beerayfarms7979]

Glad you made this video. I end up getting a few saws a year that come through on a trade for things and end up rebuilding but I don’t port. Usually just get the kits from Ryan but it’s interesting to see the various tolerances etc. Have you found it typically works better to keep the piston and cylinder mfr the same if not porting? Just wondering if they are designed to work with their own components based on the variably between the cylinders.

[@tinmanssaws]

Yeah I'd say matched piston and cylinders are a safe bet if you aren't porting.

[@JohnDoe-ud2cc]

What is better, dropping the intake port or shortening the intake skirt?

[@chrismuncey3861]

What's your thoughts on the 281XP?. I have one that's nice hasn't been used much. I want to do a gasket delete and some porting. It's a fire wood saw that might cut 2 cords a year. I want hot as I can and still use it do you have any recommendations for the 281XP thanks.

[@Leave_Nothing_Stock]

How do you keep the plating from peeling on the aftermarket cylinders? Every aftermarket cylinder ive ground on had plating coming off in slabs. Not a problem I've had with dozens of oem stihl cylinders

[@tinmanssaws]

Ive had a few peel but most are fine. Luck of the draw maybe??

[@Leave_Nothing_Stock]

@@tinmanssaws suppose I'm just unlucky. 4 out of 4 AM cylinders have peeled. 2 meteor, 1 titanikel and one standard hyway

[@chrisfleming5109]

I have a 181 husky and the piston and cylinder are badly scored, can I bore it out to take a 288 piston? or should I just get another top end?

[@yota4004]

would this not yield different numbers with different pistons?

[@GeorgiaBoyJake]

I have an Echo CS400 with a 18" bar. I need a chain that doesn't have the antikickback crap. The saw uses a 62DL .05 with bar. Can you recommend me a good chain from Oregon?

[@tinmanssaws]

Exl is a great chain

[@GeorgiaBoyJake]

@@tinmanssaws ok. Thanks! I will look into that chain.

[@ocsplc]

What I don’t get is why there are no standard timing numbers for each cylinder and piston combo based upon sets of objective situations like: no porting, or pop up piston etc.? If I’m just installing either OEM top end then why is timing even an issue if I’m not porting or using pop up? I get the squish issue. I think timing becomes a concern for people who port cylinders. But for most tinkerers like me, I don’t think I need my wheel or my digital angle gauge. Am I wrong? I know about TDC and BDC. Aren’t the crank, clutch, flywheel, needle bearing, wrist pin, piston and jug all pre-set in terms of timing assuming one doesn’t do anything crazy like advancing timing? I see dozens of guys taking timing measurements but almost never do they reveal to what end.l that is why even reasonably intelligent people are confused by it. After all, we’re not talking about souped up racing V-8’s. Help.

[@rickbryan8321]

I am somewhat confused.. farmertech makes three different brands?

[@yota4004]

saw you used motoseal right after I posted the gasket question so no gaskets I guess.

[@TDC-ih8ct]

Off to 2023

[@yota4004]

was this with or without a base gasket?

[@clauspedersen9454]

hi tinman do you have something i can do too my 254xpg husky 1998

[@coreycorp7048]

The Farmertec was copied off the Mahle cylinder thats why they are close in numbers, The Meteor and Hyway are copys of the older KS oem cylinder wich they look like on the outside and the port shape and sizes.

[@rogercrouse5531]

Why didn't you use the piston that goes with the cylinder so to be a matched set ?

[@tinmanssaws]

I measured all 4 pistons and they are the same demensions. So no need to swap .
