Huztl MS660

[Ozhoo]

you should say that i have two different cases and they are different in these ways. so i will call this whatever v1 and the other one v2 because i am making this crap up as i go along

I assumed that we were all in the same discussion and knew what the original version was

 

[Bedford T]

apparently not i am hearing from people and they are concerned about what they have.

 

[Bedford T]

i suspect that they as they always have source there parts from other guys down the street. we as a group have taken these kits and poured our hearts in them. most as a stress reliever and its been fun.

so i would bet they will have different ones i don't know why its upsetting to have tried so hard to complete an inferior being..a clone there i said it. and then have it torn over misunderstandings.

the numbers on mine are different than on yours so that is enough in its self to label it any way just be clear.

I'll look at mine and see what I have. It's one that I ordered little over a month ago. The problems Ive had to overcome are the chain adjuster problem, master control lever skipping straight to idle after choke, and my piston skirt hitting the crank lobe, And nasty castings in the ports. All in which slowed me down. A 2 hour job that took 5 but it went together better than I expected really

I've encountered several of the same problems.
Chain adjuster:

• the threads on the pinion gear, and the gear teeth themselves are fairly rough due to the tooling used to cut them being dull or worn more than OEM would allow, this makes it less than smooth as you run the adjuster back and forth- The fix - it'll wear in.
• The pocket on the case where the pinion end rests is cast too large - this causes the pinion to push away from the ring gear when you turn the ring gear - the fix - cut a 2.5mm long section of 3/16" brass tubing (documented in this thread) to act as a bushing on the end of the pinion gear, this tightens up the gap such that the pinion no longer is pushed away from the ring gear

Nasty cylinder port casting:

• Clean up with sandpaper or die grinder.

Master control lever:

• Take the lever out and cut off all of the casting flash with a razor. May have to do the same to the trigger.

I haven't cleaned this case yet but here is the measurement of the brake pins and a picture of the casting change [?]. This case was shipped out in late October.

So is that version two or more?

 

[Bedford T]

I see three different measurements

I have noticed in my last batch of the 660 kits (3) the casings aren't the same as the previous kits. The earlier ones had the ailment pins in casings that could slip out into the clutch side causing damage to the clutch side there is a vid on YouTube somewhere explaining this which is now a great upgrade but I have discovered that the chain brake mechanism isn't working on all three kits I had to resort to ordering the oem stihl part

It seemed that huztl part would almost over extend when engaging it to the lock position and then when pulling the chain brake handle back it would not disengage it without putting a small screwdriver in between the lever to help it unlock

I've had the same issue, tried adding material as a bodge to the arm, worked but shonky.

In the end genuine stihl arm fixed mine. Nice and snappy

 

[Bedford T]

At least they are actually clones so the original part makes it all better

Here's a pic of the chain adjuster fix.

If you had 5 people measuring you'd likely have 5 measurements.

So we all have the same case. That's much less confusing.

And to top it off I had same issues. So a handful of fixable things. I was starting to worry reading these later posts where the sky was falling for the new comers and lookers

 

[trboxman]

Don't know. They may have a different version case. Mine are all the same but I haven't ordered any since October. I do know that there are at least two versions of cranks and two versions of clutch covers so it's certainly not out of the realm of possibilities that there would be different versions of the cases.

[Bedford T]

At some point that would need to be a way to differentiate between them. Measurements seemed to be the only way

 

[bikemike]

So what all comes with this kit?

 

[Ozhoo]

So what all comes with this kit?

Everything to build a MS660 with the exception of the brass grommets in the cylinder cover, the air box shutter and a name plate

 

[Chris3558]

Can you talk about the brass grommets in the cylinder cover? Is it possible to post a pic of what your referring too? Thanks.

 

[Bedford T]

They are small brass bushings that the screw passed thru when you put cover on
