STIHL 026 BOGGING/STALLING....

[Jags]

Ain't no shortcuts for a carb (at least the little ones). Pull it down. They are pretty simple critters.

.....what i did was to use up all the fuel in the tank and then put in a different mix with less oil and better gas, and there is quite a noticable difference, it runs as good as it did when i first got it, so there must have been way to much oil in the last batch of fuel.....\_O_/ ( throws arms in air )

How much less oil? Did you measure it out? You may also want to check that spark arrestor... more oil usually means more carbon...

i had an uneven mix for sure....the can wasn't quite half full of gas ( which i got from my neighbor for free, but don't know what kind it was) and i tried eyeballing the amount of oil i put in...i was trying for a 40:1 ratio which is what the home depot fella recomended for the MakLmar Dolkita....but i most likely put to much oil in the there...now both my cans are empty, and i can start fresh with good gas and oil (and measure)

.....that's what i thought when i pulled one out of the little poulan....but when i looked at a diagram online, there were way more tiny parts in there than i ever imagined could be....i am just getting used to these opposable thumb things....so i'll take any shortcut i can get....if i can get a kit for under 10 bucks tho,then that's what i will prob e do.....but be prepared for more questions......maybe a lot more, heh heh.

Take pics as you go. They are pretty simple, but it could help to have something to look back on.

.....Hey Freeburn (very cool name btw) did you take the carb apart to clean it? or is it possible to clean it without having to disassemble everything? and what did you use to clean it? thanks

Yes disassembled carb take out a screw wherever there is one and shoot carb cleaner ( any parts store even WMart has it) though every hole you can see just to make sure everything is clean. There is a black rubber gasket on one side of the car be that is very sensitive just note where everything is located and make sure you do on a clean surface and not in a hurry.

....when dealing with me, try to think cro-magnon, what would a cro-mag do? or not do? would a cro-mag have a camera? not likely, so Mischa prob. doesn't have picture making machine either( i don't)....me could borrow someone's picture maker machine maybe....if i can i will because that is a good idea

....that is darn close.....the tool kit is spot on.....could use more body hair tho...unless that is mischa after a long day of waxing....sorry.....this is starting to derail like so many of my posts

 

[Ashful]

Meh... original question has been answered. Derails are sometimes more fun than on-topic, after you've seen your fortieth thread on each of the usual / perennial topics.

On tiny carbs, I've found a "GND" kit (Gasket And Diaphragm) is normally sufficient. The metering and full pump diaphragms are the biggies to replace.May not even need to replace gaskets. The full kit has needle, lever, spring. welch plugs, screen - not normally needed. GND kits are $5-8 on fleabay. When the kit is > $12, I normally say screw it and look for a new carb. Ruiing makes clone carbs of Walbro and Zama and can be $12-15.

I'm late to the party but mix is not the issue. I run 32:1 in everything. 50:1 is just a bin lean. More an epa thing.

 

[clemsonfor]

Yep a carb rebuild is necessary.

 

[clemsonfor]

Yep a carb rebuild is most likely the cause. Could be a split fuel line as well if it goes from leaning out to bogging.

In this case it could be. Unknown volume of gas that was free, so the quality and age might be suspect, and had a guesstimate of oil added to it. Starting with a known ratio is definitely an improvement.

But I agree, the ratio itself shouldn't be the cause of the trouble.

Any modern saw will run the same on 40/50:1 and not know the difference. Even at 32:1 you dont get any smoke unless your just set pig rich. O would say you could probably go to 25:1 and not see much smoke and your still going to run fine and as joful said your gonna be lean if anything !
