I feel dumb...anybody else ever done something like this?

[Mastermind]

I've learned quite a bit about chainsaws lately, most of it I've learned here. I now need the kind of stuff that only experience can give. Today I worked on a Poulan 2000 it was a nice looking little top handled saw, just dirty, and the fuel line was stiff and had broken in a few places. I replaced the line and in just a few pulls it was running really well. I started putting a bar on it so I could cut a stick or two, just to make sure it was OK. That's when I felt like a total dummy, the lugs on each side of the bar mounting stud were broken off, no way it would hold a bar...I have to learn to look stuff over a little better first...at least it was free...and my time ain't worth much anyway.

Ive gotten saws and have overlooked things. Never broke bar studs but that doesnt mean it wont happen to me one day. Keep on keepin on.

 

[chainsawwhisperer]

Yes, I've done stuff like that
My classic is going thorugh the carb on a Poulan saw that was 1/2 seized, so it felt like it has compression.

Randy,

Why would you feel that way? All of us have done it. Some of us will actually :censored: admit to it.

Welcome to the club!!

:hmm3grin2orange:

Isn't the bar stud replaceable or am I missing something else Sir ?

That's what she said.

Not the bar stud, the lugs on either side of it...someone must have stuck it and really jerked the :censored: out of it...shame is I have another case...one with a scored piston...it has a crack in it right by the bar stud. Bad design maybe...

LOL someday you'll slip...I'll be watchin...

Dumb and dumber

I was given a MS 280 recently and when I got it home I fired it up. The noise it made hurt my ears and scared me. I thought it was going to explode.
I checked the piston through the exhuast port and both crank bearings and could not find anything wrong.
My diagnoise was a bad rod bearing. I proceeded to tear it down until the only thing left to remove was the clutch, clutch bell, brake mechanism, and oiler and could not find any thing wrong. The P & C looked new, all bearings were good. Finally I checker the clutch and the spring that runs the oil pump was not as it should be. That is the only thing that I could find wrong. It is hard to believe that it could cause so much noise. I have not got it back together. I hope the new oiler part is the answer.
Everyone who has worked on something has done dumb things, some will admit it and some will not. Tom

You could make some .322" diameter pins , drill the case and bond the pins in to repair it.

I bolted and torqued the heads on a 350 V8 once and didn't install the pistons first....

Oh my, that's a bad one. Course, if you were talking about an old IHC Farmall engine, you could install pistons from the bottom.

I rebuilt an 045 Stihl and found the wrist pin clips underneath when I picked up the saw to fire it up.

One of my first small blocks, 283 I think, primed oil pump, dropped in the distributor, primed with gas, ran good for about 10 seconds. You can figure out what happened.

Old man walked up and said, and this is priceless,

Whad' ya do now dumb :censored:,

Learned a very valuable lesson on oil pump shafts that day.
Just an irrigation motor, man was he pissed.

:bang:

You don't have to watch too hard...I'm good for at least 1 big screwup a week.

been there done that but caught it before I fired it up, the distributor went in to easy is what made me look.

I thought about that, but it's only about 1/8" thick, and I planned on selling it, I can't sell something that's crap...not if I know about it.

I was quite surprised when I joined the United States Air Force and found out my middle name wasn't dumb :censored:.

Of course they called me allot of other things. I had no idea my family went back that many generations.

One spring I rebuilt one of my race engines that layed in the unheated back part of the shop all winter.

Didnt know till it was in the car and filled the radiator that the motor must have had enough water in it to freeze and crack the block behind the back cylinder. :bang:

My Poulan 2000 bar stud stripped the magnesium and I drilled and tapped it for a helicoil. I'd say that the magnesium was about 1.5" thick at the bar stud hole. You're sure that the case is 1/8" thick right next to the bar stud?

Well, when I was tearing it down, bar oil was running out of the spot where the lug was at and the chipped out piece is only about an 1/8 deep. It's a moot point now I've completely disassembled it and the parts are listed for sale...
