Stihl 026 Won't Start

[secureland]

This 026 belongs to my wife's grandfather. It will start if I drip some gas in the carb. But that's it, what should I troubleshoot to get this going? Also, the choke/stop device is will not go to half choke. It have to force it into the choke position.
I showed this picture because the white plastic piece from inside the air-filter cover is loose, and I'm not sure how to reapply it.
My goal is to get this saw running and repair the choke/stop device (proper name?), get the air filter cover reassembled, sharpen the chain, clean the saw and give it back to her grandfather.

Thanks for any help,
Bill

Fix it then....

That white thing goes INSIDE the air filter. Split the air filter, there is a little slot on the side, and that little white piece slips under the choke flap. It only goes one way, concave side toward you, with the little groove for the spring at bottom, and the holes for the mounting screws at a diagonal. That might also fix the choke actuation problem as well.

Are you saying it will start and keep running if you drop gas in the carb or just run until that burns out? If it keeps running , fix the choke and you are good to go. If it cuts off, you will probably need a carburetor kit.

Yep. There are people in Kansas that actually know enough to help somebody.

It cuts out after it uses the fuel, and wont start unless I drip a bit more in it.

Nope, I was in Topeka, but Carbondale and Scranton had baseballs. I heard Manhattan had grapefruits. Yow. Not a good time to be hitchhiking.....
(I saw a kid at the turnpike onramp this morning, but I was running late.)

You may be able to clean the carburetor. No more than a kit cost it makes more sense to just rebuild it. Make sure your gas line and impulse hose is in good shape.

PM me if you need a manual and IPL, will have it to you in the afternoon.

I was in Junction City, and it got real ugly. I havent seen day turn to night at 9 in the morning for a long time...saw a lot of cars on wreckers that looked like someone took a sledgehamer to them. I got the hell outta there when the hail started.

Look dude, dont start throwing insults at me. You have no clue what you are talking about.

OK dude. I was just trying to find one tiny bit of usefullness in that.

Maybe not. But, myself and a lot of people on this forum could fix his saw for him in short order regardless of what is wrong with it. Can you?

Is cleaning the same as rebuilding? Where can I get the kits ou are mentioning? I'll check the gas line and impulse hose.

Thanks,

rebuilding is normally cleaning then putting new parts in, or sometimes just serious cleaning. In the case of a carb, it's putting a 'rebuild kit' in - that's just a bunch of new gaskets and diaphrams and maybe a needle. First I'd check the impules line, fuel line, and fuel filter. These are simpler and cheaper and problems with them may cause it to only fire with fuel down the throat. If you want to know more details, keep asking...

edit oh and after those lines, there's another fuel filter/screen inside the crab that can be blocked if the fuel filter has failed

Try Baileys which is a sponser of this forum and has a direct link. Walbro K20 WAT $8.95 These kits often fit more than one carb configuration so you may have parts you don't use. Just put back in the way it came out. Soak your disassembled carb in carburetor cleaner and blow it out with an air hose.

Before you get too far down the road , make sure the saw doesn't have more serious problems. It should have enough compression for you to hold it up by the starting rope handle and the weight of the saw not pull the rope out. Or better, borrow a compression gauge from somebody. Also, pull the muffler off and make sure the piston doesn't have any scoring, vertical scratches form raw or incorrect mix.

Be careful blowing air into the carb. You can ruin the outlet valve. at best, a gentle ait wash a few inches away.

Cleaning...

Take the carb apart and take out the H&L screws. Using a can of carb cleaner with a long nozzle, squirt up the H jet with your finger covering the H inlet in the metering chamber. You'll see fluid come out of the outlet valve in the venturi. Then the L - cover the L inlet hole, and you'll see fluid come out of the three progression jets in the venturi near the throttle plate. A quick squirt in the inlet valve hole and you're done. Air is not required..



Watch your eyes... fluid can squirt out at you if you don't know what you are doing...

Or even if you think you know what your doing!!!

so true....nothing quite like carb cleaner in the eye


I turn the carb metering chamber away from me... then squirt cleaner into the H/L needle holes and see where it leaves the metering chamber. Then I know which hole to put my finger over!


BTW.. this technique will not work as described for all carbs. It does for the 026 and similar though.

Cool. I was explaining the way it has often worked effectively for me.Yet to ruin one that way, but it's good to know that it can happen.
