064 need suggestions

[paragonbuilder]

Damn that's some carnage.

The last 044 I did stalled and made a mechanical clank. My heart sunk.

Wound up having the carb adjusted wrong and it threw a flywheel fin. Was I ever lucky.

I bet there were a few choice words thrown Doc.[emoji16]

According to the original post, the saw was not built by Brad. I have no clue who in fact built it.
Doesn't matter to me. I've just never witnessed a saw lock up on video like that and had to share.
Kinda looks like it snagged a port heading towards BDC and the windows & rod let go

What a mess!

What a mess!

I feel sorry for the owner of this saw!

 

[Edwad]

Interesting!

Yeah, what an unfortunate experience. Hopefully it will all get worked out.

You would hope so.

Dan have you ever experienced anything like this?

It does happen, I had a cracked piston in my 066. It was an oem piston with only the windows opened a touch.

Whole skirt was bout ready to come off

No. I haven't Mike.

I've seen a wrist pin bearing blow apart also, not pretty

Yup. I'm sure it'll happen to me as I play with more saws, eventually...

I took my lightened piston out of my 64 hybrid. They may be ok but IMO they have no place in a worksaw

I have! Widening the intake port too much and making it too square will snag a ring and make them go boom!! I speak from experience!!

Bet you are right about that Keith.

 

[Keith Gandy]

Bet you are right about that Keith.

I cant say for sure one way or the other but when something goes wrong like a snagged ring usually a piston wont come completely apart but having it lightened cant help IMO. They may be fine but in my mind I dont trust them and for my own peace of mind I took mine out

 

[Keith Gandy]

That paticular video was the worst I have ever seen!! Violent mess!! Most I have seen usually catch a ring and score the mess out of the cylinder, lose compression, and just go dead

 

[laslabjohn]

That is just wild, and a complete shame..

 

[mdavlee]

It was a bad come apart. The metallic clank at the end sucks. I've had one piston come apart starting it. Never got to full revs. It didn't sound anything like that.

Did Brad determine what was the cause of this catastrophe?
