Checking on my JMS 066

[Moparmyway]

2 out of 3

064- Very Faint exhaust scoring has JMS etched into the crown Rings look good.
7900- like the day I sent it..... perfect
661.... Intake..... however I wanna blame the HD2 on that

Exhaust is fine

Probably will tear down all 3 soon


All run very strong and have no issues running

I've ran the hell out of these saws, more than 5 gallons each on these saws during my ownership after porting.

Don't wanna really stop using them, they all run good. I know some will say run till they blow and others will say send out.

Money is sort of tight lately. By all means I don't want a handout here!!! I guess I will just have to wait this out.



This kinda blows!!!!

If you're going to run the 064, make it a little bit richer on the high end. Added insurance.

Whats she tuned to ?

I stuck up for him and it's one thing to see more recent port jobs turn out this way to maybe see a pattern and I feel bad for everyone involved here. These saws do run strong however this is not right.

However seeing a saw from a couple years ago turn out the same way... I don't think it's a matter of "if" I think it's "when"

He reccomended 14.7

It 4 strokes lightly there

However I run it at 13.8 14.0 which produces a very strong 4 stroke.

14,700 ???



13,500 - 13,600 for working is where I run mine. You'll barely notice that little bit, but that saw and its bearings certainly will

 

[Jon1212]

Damn. I still think it's all my fault. My inability to tune the saw.

But seriously, I hate to see this. He really needs a new career path...something involving fecal matter.

Based off of the quality or lack thereof, I'd have to say he is already quite adept at producing fecal matter.

 

[CR500]

On the bright side though...I guess the 064 will become an 066!!!! lol

 

[dall]

No, I'm saying there should not be people like Jason in the world!

I have never had to pull my saws apart that were done by Randy, Dr Al, CFB or Bret! There is just no reason.

mike I'm with you on those builders as I have saws from randy, al, cfb mike, mike lee, Redfin, Huskihl and tree monkey Scott

he told me 14500 but best power is mid 13s
When I got mine from Scott I had to detune from 14200 from his mix and altitude to 13600 felt good I've found best torque is lower than when it quits 4 stroking

Touché

661.... Intake.....

Every 661 Ive been into has intake side wear. Even one that left the dealer with no required fire. Just a heads up.

Nearly EVERY saw does that.

If you want to speak french, at least do it right!

Vous avez blessé mes sentiments

This looks to me like a cylinder that was well worn before it was ever ported, not a result of the porting. Unless the machining is grossly out of square, I'm going to be slow to jump on the band wagon on this cylinder. Does that make sense? No, I don't use bridge and finger ports, but they look OK from here. But like I said, I've never used them before. How much support is needed after the grinding? I really don't know.

Yeah. I don't like that part. That's why I commented on the cylinder alone. I wonder how much of that is old. If all new, then there's a definite problem.

I probably shouldn't even comment on bridge and finger ports because I've never used them. However, it's impossible to use them without a significant loss of support, particularly with finger ports.

Have to remember that in order to run a 066/660 with finger ports, the piston gets installed backwards, that is, the exhaust side of the piston rides on the intake side of the cylinder.

Now, lets have another look at the piston and cylinder wear ..........................

Also, the intake and transfer on the left side (as pictured in post #6 ) are crossing into each other. So when the transferrs are flowing in the fingers, they are also seeping into the intake, as well as when the intake is trying to suck in from the carb, they are also sucking in from the finger when the piston ring is below the finger opening

Skirt and oil should seal that if there's not excessive clearance and a spot of plating in between.

The saws are a ticking time bomb. Which is why I'm rebuilding 3 of them slowly as I'm financially hurt from this bull *s-word. I have a lot to say. But to sum it up he can port a saw but he cobbles together *s-word and it runs like *s-word.... Wasted talent. Not to mention parts swapping. Check out my nice 395 cases that were supposed to be painted and all good... HA yeah right. The huge chunk of the cases that broke out also located the pin that aligns the chain brake so the clutch drum always rubs on the brake band . I was going to just rebuild it off these cases but looks like that ain't happening. New case half is required. And I have barely scratched the surface in opening this can of worms. I am at least more than 400$ in the hole from shipping saws alone to that mother *f-worder and the saws themselves never ran right out of the box and always needed some bull *s-word part that was *f-worded up. Nearly every single mechanical part you can imagine on the saws was wore out old junk that was cobbled together. Hell my ported 365 popped out his junk circlip and trashed the saw. Or the 394 that blew up the "brand new" crank bearings at NY gtg. Hell its never his fault either, always someone else's. I didn't tell anyone as I felt it would draw attention to him, I did it out of respect for him. Which I have no more. I have been waiting 3 months to get the *f-wording 372 back that will end up probably needing a new cylinder and it's always some excuse oh no money no time oh it needs this *f-wordin part. *f-word you I don't have any money as a result of this *a-hole. To say I'm beyond pissed is a understatement. I have 2 saws sitting here I refuse to use as they will blow up sooner or later the question is WHEN. Now I have to pour more money I don't have into them to where it's almost pointless. I've given up on them. I was not going to say anything out of fear seeing how he threatened Julian (redbull661) and other members. I hope this helps someone in some way so they don't end up like me or many others....

That is brutal. Hopefully you'll be able to get your saws back into proper working order without too much extra cost.
After I sent my 066, and got it back..I was seriously contemplating him doing at least a 395... so glad I didn't.
Would have happened before all the *s-word hit the fan.

 

[huskyboy]

@Manofstihl066 I can see why you smashed the *s-word out of that 064. I should have done that from get go as it would have been less fustrastion in long run.

Wow!!! You can't make this *s-word up. Unbelievable.

I think I have a good 395 case at home you can have. I'll look later tonight when I get home.

Not, it's never the tool's fault. Just calm down and get all if this crap fixed.
