STIHL CHAINSAW EXPERT NEEDED

[HarleyT]

The main thing,
if your saw starts acting squirrelly......
Fix it correctly....

 

[JWMUSTANGMAN]

ok, so you would look for those before replacing anything?

 

[HarleyT]

Usually, the carb adjustment ones,

the owner was trying to compensate for another problem....

 

[HarleyT]

Usually the problem is in the fuel system, so I go through that.
With things apart, close inspection of lines, boot, replacing the carb kit.
The carb kit should be replaced from time to time any way.
The main thing is to see if you need a cylinder, or just a new piston....

 

[HarleyT]

That being said, doing a leakdown test is simple. All you have to do is block off the intake and exhaust, and see if the crankcase holds air. And while at that, see if it holds vacuum.
Not real hard to do.

 

[HarleyT]

A piece of rubber under the muffler usually blocks off the exhaust quite easily, and a cork in the intake boot does the intake, and use the impulse hose for your testing.

Seems like some folks are fixated on playing with pumps and vacuums all day instead of fixing a simple problem. There's no reason to charge customers extra to get parts tested that need changed anyways. Troubleshooting a newer saw is one thing, but most of the older used saws in question have been ridden hard and put up wet. It doesn't take a rocket scientist to know what they'll need.
Advising someone to go out and buy a bunch of technical equipment when they may never fix more then one saw is silly, especially when the parts they're testing costs less than the specialty tools.

I appreciate your input. I was actually wondering about just replacing some of this stuff instead of investing in the test equipment. But if I'm going to fool with this stuff, I might be better off to buy the equipment. Where is the balance?

How much do you value your time/money ? If you want to invest in the tools such that you can repair Everything than plan on dropping some bucks and going thru a learning curve / mistakes / cost money ... just like everything else ... lotsa guys wanna port saws but when you add cost of lathe ; tooling , stock porting tools ; micrometers, dial indicator etc etc etc you better damn well enjoy it / make a sellable product / use commercially for profit / or you can quickly find yourself into it for thousands of dollars! There is no “free lunch”... another consideration is the age/condition of the Saw itself - sometimes you are better off parting them out then fixing them .... most pros that run 6 hrs a day buy new and run the snot out of em until they feel em loosing powa ... then it’s ebay/Craigslist time for 1/2 price of new ; sell and then buy a new saw again ; rinse and repeat- this may tell ya something hmm

 

[HarleyT]

Take the saw down slightly. Remove the carb, muffler, starter, bar/chain/cover, and top.

And take some pics and put up here.

The dialog will change quickly...

 

[HarleyT]

Look at everything closely, take pics, as well as the piston through the exhaust and intake.

This thread will go immediately in a new direction.

This isn't about porting saws motard. I'm not sure why all of your posts evolve back to the same regurgitated ********, IF you KNOW what I mean.

The tools in reference are to do a pressure / vacuum check. OP wasn't asking about porting tools or their application.

Yah , remember when I asked for your opinion ? Me neither ... now run along junior

Bro he is talking about press/vac testing not porting saws

I see I wasn’t the only one realizing this clown is comparing apples with oranges. Talking about buying lathes and ****, what a toolbag

He's a damn troll. He shows up in every thread talking his psycho'd insanosized 241c that he built, which was actually built by Hotsaws101, IF you KNOW what I mean...

Typical big city mouth, trash talking, condescending, unwarranted arrogance, parrots others opinions as his own, yada, yada, yada. I had him on ignore for a while but some of the threads weren't making sense without his drivel present.

Not sure how old he is, but no self-respecting man would drop DA bombs and the ghetto ******** talk. My cousin Vinnie's window-licking cousin, you are...

Yah ... I’m trying really hard to see things from your perspective but I’m having trouble getting my head that far up my behind !

Hello all. I'm a fan of Stihls. Have been for a while. I have several, but I am down to my 029 as my last one running. I'll list my others here and what I "think" I know might be wrong with them. Any and all help on how to fix it would be great. I want one of my big ones running again!

Stihl 029:
My faithful little "trim saw" with 16" bar. I've been using it for everything since its the only one still running.

Stihl 045 AV:
My dad used this for years til somebody put the wrong mix fuel in it. I think it got 16:1 or 32:1 instead of 50:1. Once it shut off, we realized what had happened. This was like 20 years ago and it hasn't been fooled with since.

Stihl 046 Magnum:
Best $100 bill I ever spent. Bought it at a pawn shop and used it for about 10 years. It broke a piece of carbon loose from the compression release and scored the cyl wall. I bought a new piston/cyl and put it in. It ran good for about 1-2 hours run time after that, then acted like it locked up. Not sure what's up with that.

Stihl 064:
Kind of stumbled into this one. I was at a pawn shop looking at a log splitter for $600. I told him I would take it if he would throw in the 064 I saw on the shelf. I was shocked when they said "deal!" haha I used it only a few times before it quit running on me. Just kind of slowed down and stopped. after that it would crank over, but not try to start. Would LOVE to get this one going.

Stihl 075:
What can you say about a saw that has a 111cc motor? haha My grandpa bought this when he logged off some of his timber in Vermont. He gave it to me before he passed away. It didn't run when I got it from him, but I would LOVE to have it going for nostalgia more than anything. But you better believe I'd use it if I had it running.

Ok, best case there is a Stihl expert near me here in East TN that would help me look at them. Sure, I could take them to a shop and "have them fixed", but I want to do it myself. I need a little guidance to get going, and then I'm confident I could handle it. I've always worked on my own stuff. I've rebuilt several motors for other stuff, but chainsaws are a new field for me. If there isn't a nearby guru that can help, can anybody point me in the direction of where to start? Which of what I described would be the (possibly) easiest to fix? Any help would be appreciated.

Thanks in advance!

Wished ya was closer. You will find it’s fun to tinker with them.

Hey, if you are in Mt Juliet, TN, I might be closer than you think. I have family in Nashville and make visits there many times a year.
