How does the scheaffers 7000 tcw-3 perform in the 4-mix engine.? I currently run saber at 40:1 in a stihl fs130. I run scheaffer oils in my truck as well as the mower and the local rep can get the 7000 “boat oil” for me as well…. Just curious as I can’t find anyone who has run that oil in a 4-mix..love your channel by the way…

You should have t-shirts made with a logger cutting a 28" tree with a 32" bar about 1/3rd into it with chips flying everywhere that just says, " Full Tilt Boogie". Ide buy a shirt like that

MOTUL 710 2T

Sounds beautiful. Very crisp on the throttle.

I hear you can run . 58 in a worn . 50 bar and it will be less wobble

I’ll just stick with running Amsoil Saber mixed at 40:1 in 90 octane ethanol free gas. The local Husqvarna dealer sells Saber for $18/qt. I don’t care about saving a few pennies by running a leaner mix, I just want all of my 2 strokes protected.

Lucas is NOT FD rated. Lucas CLAIMS that the oil MEETS FD standards but has not paid the money to have it actually tested. However, I use it and like it for the price.

In a previous video, you mentioned the degreaser you purchase at a local business. Since it's safe to use in aluminum, do you know if the big box stores carry an equivalent degreaser? Thanks.

This is not strictly a comment on this vid but, hey, it's all oil, so here's another question. Do you know of any problems that might result from mixing different oils in good E0 gasoline? I can't, and thinking abut it I realized I've been doing that to one extent or another since I first started using power equipment a VERY long time ago. Just to narrow this a bit, let's stipulate that we're talking about oils from reputable sources, even if we might not be crazy about the specific product. So to make the question a little more concrete, do you think there are specific reasons not to mix, say, Husky pre-mix with Stihl pre-mix with Red Armor pre-mix? And without intending to make a comment either way on TruFuel products, let's stipulate that for purposes of this question we're not including either of the TF pre-mix produccts. I wouldn't make mixing different fuel mixes a practice, but I can't think of any reason not to do it occasionally, either. A pre-mix that has cr@p oil that leaves a lot of carbon would be a reason...but I don't think any of the three I mentioned as examples fall into that category, even if one or the other isn't "the best." Even winding up with a mix that had some full synthetic oil and some dino oil doesn't seem like it would automatically be a problem. Anyway...thoughts, pronouncements, opinions, whatever...?

Hey that’s awesome! Sounds like you were able to save the cylinder. I just picked up two 044’s that are both the 10mm red switch but one has a aftermarket no branded cylinder so I’m going to pick up a used slant fin to try to bring it back to original. Hopefully I’ll have two really nice restored work saws.

How long have they used ultra in this saw is the real question.

Richard, how do you flush the crankcase?

That's the new magnesium piston I think

Love your videos. Getting ready to rebuild my 034 that my ex’s husband messed up. I think he ran straight gas in it😡😡😡

Mr. Richard, I see that piston is indeed available. Stand alone...

They are coated in tin. 32:1 Dominator, runs in everything, tunes in everything. Half the cost of all the other oils at leaner the same ratios.

I’d never run ANY oil at 100:1! 40:1 at the least but I prefer 32:1. 32:1 is what I run in my 371XT AND 365XT and everything else that I run. I run them hard and I don’t even have a compressor to blow them out BUT I do knock as much off/out as I can.

100:1, maybe at idle with a pump oil sytem, I'm sceptical and that barrel is the reason, it should probaly get a hone, help the new rings seat.

Hey Richard great info for adjusting the valve. I have not don't that yet but I guess it is the same for the FS 90?

hello richard very interesting video as always I bought a ms 400 she has 1 month I ride a pure alkilate gasoline mixed with oil 2 t bardahl special motoculture at 43/1 Is it good? I gave up too expensive husqvarna oil xp here in France bardhal 100% synthesis jaso FD I noticed alkilate gasoline no carbon problem even with stihl oil ultra FB or other low-end oil the only problem is very expensive or it is necessary to drive from time to time with the bad gasoline of the pump stihl does not want me to put 2 t motorcycle oil otherwise no guarantee

I've bought Bel-Ray MC-1 by the case from 1978 to this day for my 2st offroad racebikes , the last 24 yrs l've had an Echo string trimmer , leaf blower & a chainsaw , 100% of the time l mix up Echo power blend gold but when l'm out & l have a jug of MC-1 at 50-1 made up for the KTM l don't hesitate to use it to get the job done .

Great video! Do the newer saws in general seem less durable than their predecessors? I was poking around on German TH-cam channels earlier this spring and saw mention of a newer version saw in the MS400 class. Any word on your end of this? Could it be a fuel injected version? 👍

Tho I dont forsee running anything lighter on oil than 50:1, just the fact there's oils out there that can keep an engine alive at 100:1 is impressive to me!

Sorry to be a killjoy, but I'll stick with my Echo trimmers as confirmed by this video.

Stihl not worth it... 🙃 4 mix is just more shit to wear & break. The FS74-FS85 series were the best ones that Stihl ever made.

Always been interested in the 4-mix engines. Seems like a terrific yet terrible idea. But after years of thinking about it, I just got a new fs 131 r this weekend! Definitely different. Think I'm gonna like it🤞🏻 Tuning is something im not quite sure about yet. I've got the low jet set to slightly "stumble" and the high set for what feels like best power buried in weeds lol low and high jets were definitely too lean out of the box.

Sabre is just on $50 a quart here in New Zealand, but worth every penny. Can't get HP2 here. The 661 loves it at 40:1, burns so clean. I've just ordered a monster MS162 today, for those annoying tiny branches on trees..be interesting as they seem to be a love it or hate it saw. $335 in NZ

Nice vid and info....

I used to have my grandpas FS90R and if I adjusted the valves with the feeler gauge you have the thing would start hard and have real soggy bottom end and poor throttle response. If I set the valves at double the spec it always started first pull and revved right to the limiter and had all kinds of low end torque and response. I tried a couple of different carbs and coils also didn't make a difference when the valves were set to spec. Ever experienced anything like that with these before? I wound up selling it because of that.

Yup, blows my mind when you see OPTI-2 at the parts counter in the big dealership that sells the 3 orange saw brands and the parts guy is raving about how cheap it is and how convenient it is…I guess it keeps them busy with rebuilds or selling new saws. Good work on the new bearing, probably some of the chrome coating got scuffed up from the aluminum filings from the scuff on the piston. Speaking of clearance issues from factory test run, I had a new 390XP to port a couple years ago for a Heli-logger on the west coast. When I pulled the jug, it was well scuffed and so was the piston on the intake side…wasn’t very impressed…that was a 2020 model. Take care!

Rich nice explanation ❤❤❤ Great detailed info 😊😊😊

Rich nice video ❤❤❤ Great work 😊😊😊

I just put a new piston in my “low hour” 12mm 044, I bought it from an older gentleman that only used Stihl oil. Saws in great shape but a chunk of carbon broke off the exhaust port and got sucked it, it didn’t do a ton of damage but after your videos and my experience I’ve switched to Sabre 50:1 this year, luckily I have an independent dealer that lives about 5 miles from me, ALL of my stihl equipment (with much use) has had carbon issues. Hopefully Sabre is the answer. Thanks for the great info Richard

Wow good video Glad the cylinder cleaned up on the ms 400. I guess I will not be using 100-1 oil mix. That VP 40-1 oil I run excellent no carbon buildup and no piston wear after 5 tanks.

I was going to make a crude joke about 2 fingers but I'll just help the algorithm instead

Enjoyed the video. Good to see you.

Godd stuff!

I enjoy your videos. I've always ran motorcycles 2 stroke oils in my gear and seeing the results in your previous videos made me feel that bit more confident that it was the correct choice to have made. In saying that. The 100:1 you ran was wild to me haha, seems like so little oil in a environment like a chainsaw... turns out it was 😂 Looking forward to the next. Cheers mate.

Well i can get Belray H1r in town so ive been using it! Seems good! Thanks for all you do!

Bearings always sound like that after being cleaned. Add a drop of oil and the sound will go away.

That jug polished up nicely. Don't spend all that TH-cam money in one place now...

Do you think the failed bearing was just from grit and debris or do you think the 100:1 wasn't enough to keep the bearing lubed? And why just that one bearing? I thought you said the crank side had a nylon cage and then we have the needle bearing on the rod, but the metal caged bearing is the only one that failed. This is the stuff that gets my gears turning.

Labor is "free"... Bwahahahaha!!! Thanks for all the hard work.

Cat food and ass😂 I love it. I still think you should try klotz oil. We ran that for so many years in our snowmobiles and dirt bikes with great results

Nice informative video Rich. Looks like everything went as planned with that magnesium piston. Lighter softer metal to save the cylinder as designed by Stihl. Sorry to see the damage, but thanks for taking one for the team. Looking forward to the 2nd part.

That’s gonna be a sweet saw!😊

I stick to 40:1 no matter what oil brand it's just plain fact that these little two strokes need a certain amount of oil for the bearings along with P&C's to survive. Tried different ratios with some of these newer oils a few years back but I could always smell what seemed to me to be a "hot metal" smell, so that told me it was only a matter of time before big trouble so back to 40:1 and will be staying there no matter the brand of oil or their marketing claims.

A plastic camshaft ? Good grief, Homelite quality in an overpriced Stihl product. The only good Stihl string trimmer I have ever had is a real old one that was actually a Kioritz built model. It has lasted forever.

I have recently rebuilt an MS400 as well, is it normal to have a little dead-zone in the throttle before it starts advancing the throttle? Husqvarna saws seem to have a lot nicer throttle control imo.

As much as I LOVE Saber I don't even trust it at 100:1. So I sure as heck wouldn't trust this Opti-2 stuff at 100:1 especially in a $1,200 saw. Sadly finding Saber in my area is like looking for hens teeth. The one dealer I bought my original bottle from a few years ago no longer sells it. But I did find a dealer who sells it in the next state over. Luckily it's no further a drive then when we go grocery shopping locally. Everything around here is so spread out so 30 minutes to an hour is standard travel time. For now I have a couple bottles of VP-Racing oil, two other bottles of AMSOIL and some ECHO Gold Blend to use up. :)
