Well folks, It all started like this.

Found this nice saw at the bottom of a pile and thought "this would be great for my first ever fix" I have always wanted a McCulloch.

I have a week off from work and wanted a project. I got this saw all cleaned up and out. Made it look like new!!!!!
Couldnt believe that after cleaning out the tanks, and all the dust and muck from every corners corner that the thing started.
Man how great. It wasnt running all that bad but I wanted to put a carb kit in it and replace the cracked fuel line.

Got the kit in and replaced the fuel line. Got it somewhat adjusted and out to the wood pile for some final adjusting (cut - adjust, cut - adjust)
Well I was at the point where I thought this would be my last adjustment. Had it running and the little bolt that goes through the air filter that the cover screws onto (here it goes - drum roll please) comes off the plate and in slow motion I see it go down into the carb hole.

Thats when I heard Mother Nature say "I HATE YOU TBOW388"

So much for my first fix!!:angrysoapbox::angry2::taped:
 
DANG!!!! Its junk now. Should be a good parts saw and that had a nice bar and chain on it to. They are cheap and easy to come by...you could rebuild it, make it better than new.......it could be the 6,000,000 dollar chainsaw! Stronger, faster.... sorry.


JUNK it or you could tear it apart to see what happened for the fun of it...

Did it just lock up or run for a second or two before it died? Poor thing!
 
If it was at idle, the screw could not have gotten past the throttle plate. Where you revving it?
 
Heck, at least look and see what happened before you give it last rights. I bet it isn't as bad as you think.
 
I was testing a big saw on the bench (740? 795?) and watch the foam absorber from the spit back collector disappear into the saw intake, of course it was running at WOT.

The saw never missed a beat, I never saw even a puff of smoke or smelled buring plastic or rubber, but the absorber was gone for good.

I wonder if perhaps it is still floating around in the crankcase? None the less the saw would start and run from then on as if nothing ever happened.

A screw might cause a little more damage, but I suspect if you posted this over in the McCulloch Chain Saw thread in the stickies you'd have offers for the parts the same day...

Even if you don'e, the 10-10 saws were very plentiful and finding parts you need should not be any problem.

Stupid thing.

Oh I was revving it. Took the carb off and there is a lovely big nasty ripped like hole. I am assuming thats the demolished piston.

Since it is my first fix i was to find a piston and jug for it.

Rev revv CURRLUNK. deaddddddd
 
Need pics of the carnage...

This is something we all dread... something coming loose at an inopportune time... and getting sucked into the engine...

At least it wasn't one of those huge cargo ship engines... I'd hate to be the guy that has to pay the repair bill on one of them...:dizzy:

Oh, and now that you mention this, I think I'm going to be tack welding them little bolts onto the plate... I'll do anything to keep that bastard known as "Murphy" of the infamous Murphy's Laws the hell away from me...

won't be too hard to fix or to expensive. Might be time to look for that 70cc block and strap on the 10-10 parts. 70cc's are more fun than 54cc's.
 
Sometimes Murphy just pops loose and falls in the wrong place!!:eek2:

Looks like u need a parts saw! Shall I bring it Tuesday?:msp_confused:
 
That'll buff out.







If it was worth messing with to start out, then it's worth messing with some more. Jug may actually be fine if it just went thru the top of the piston. Harder to tell though if it did any damage to the crank or to the connecting rod when the piston topped out early. Do a tear down and assess the rest of the carnage, take more great photos and post them up. Everyone here feels your pain more than you think.
 
As asked for

This next picture is for mature audiences only. I call this my "pist-off" picture of my "pist-on"

By the way, I need a piston and rings. Anybody got a good one?
 
meh, that piston'll run. Just cut off the bad part, and approx the same amount off the other side and throw it back in there... ;)
