Hutzl MS660 build and observations

[Wood Chopper]

This ain’t no 661 lol. but for what it is it pulls a 36” bar if I need it to,which is rare. I’m gonna turn the H screw in this weekend. She’s got enough tanks through her now.

Did you install the Farmerteck wrist pin clips? I didn't see that in your list of OEM parts. I've heard of those failing on that model saw. You may want to go OEM on that, or cut the long arm off the clips, I think that was the problem.

Other than that I would like to see a video. No power and clutch slipping sounds kind of like it isn't leaned out enough, but don't know for sure.

Hey Billy. For the saw in that video there is nothing oem except the decompression valve. I did cut the ears off the wrist pin clips. The saw is tuned to about 12,800 Next time out shes gonna get leaned out.


Billy just realized you were talking to Op my bad!!!!

Now that's a pull starter handle!!

Any problems with the cranks?

 

[MustangMike]

I have not had any, and I've done a fair amount of milling with them.

 

[Wood Chopper]

None with cranks here either. I had my first real “failure” last weekend. The rubber av mount on the upper right hand side behind the handle bar mount separated from the metal piece. Lol

Hi All,

So about a month ago a tree came down in my street. It was a government one but I wanted the wood so I took the 660 out there to get it. I didn't get a video because your technically not meant to take the wood I think, but I can confirm the 660 is running well now. I leaned it right out - its revving to 12500 now - and it hammered. I did test cuts next to my other 72cc Chinese saw - which is my primary wood cutting saw - and it blew it away. There was no comparison.

I still haven't made it to my mates farm, but the weather has turned here and my wood sheds almost empty so I will be down there within 2 weeks at the latest. Ill definitely do some videos then and upload to share. Hopefully i'll get to do a side by side comparison with my mates 391 and 661 to see how it stacks up.

Thanks all for the input and advice.

Brendan

Was it "break in" or re-tuning the carb?

 

[YZ250]

Hi Mike,

It was just from tuning the carb. Its probably still breaking in to be honest - ive only put four or five tanks through it. My 9year old daughter took some footage of me using it on the weekend but its pretty dodgy so will require a fair bit of editing before I can upload. I had the full 20 inch bar buried into a piece of brown barrel and it was cutting with ease. The video shows this alternating with various artistic shots, close ups of the ground and unnecessary zoom ins.....

I still really want to do a 'saw off' with some of my mates genuine stihls but that will take some time to organize. In the mean time I am very happy with it! I really want to do an MS200T build now but am baulking at the cost.

All the best video footage is from young children,

You get to see what’s going on in the heads.

My son was the same.

One but that's it all the others are holding up just fine.

 

[YZ250]

Ok guys, here’s a quick vid of it running. Brown Barrel is pretty tough as far as timber cutting goes, but it gets much worse (Iron Bark etc). I reckon it could probably do with further tuning but keen for your thoughts.

Sounds good but who you got running the camera could learn to sit still. Lol.

Ha ha, yeah and this is the edited version. Some of the other stuff she took would induce motion sickness.

So you don’t reckon it needs further leaning out? How many RPM should it hold whilst In a cut?

 

[MustangMike]

As long as it 4 strokes out of the cut and cleans up in the cut you should be OK.

However, some saws run better a little rich, others at the ragged edge of lean.

You just have to learn what your saw likes.

I have heard of tuning it the cut, but the ability to end up too lean doing this scares me.

Thanks mike. Sounds like a day tinkering in the field is in order

 

[MustangMike]

Keep in mind that temp/elevation and humidity changes all may require a change in tune.

Some of my saws are not finicky with this, others are.

Like what mustang Mike said he beat me to the punch.lol

Most saws will cut the fastest loaded at 9-10k in cut I have found. Don’t tune to a specific rpm in the cut just tune it normally like Mike said.
