026 Carburetor Rebuild - The Saga Continues

[woodeneye]

Could this be something as simple as the impulse line?

 

[woodeneye]

Yeah, I have spark. Man, this is strange.

 

[woodeneye]

Thinking about putting the rebuilt carb back in. At least it was firing with it in. Wonder why?

yes u have to have pressure from the bottomend through the impulse line for the carb to function. spriz alil fuel through plug hole on top of piston and see if she will fire?

 

[woodeneye]

Ok, I'll go try that. Thanks.

 

[woodeneye]

Nope, it didn't even fire with fuel in the plug hole.

 

[cedarshark]

Does that saw have enough compression(measured w/ a gauge) to run?

 

[woodeneye]

Yes and it has ran for a few a few minutes at a time. It has 125 according to my gauge and I know my gauge runs way low compared to a good one.

 

[cedarshark]

Then the only thing that would cause that saw not to at least cough on fuel in the carb or plug hole is insufficient spark or spark at the wrong time. Sheared flywheel key or weak coil ?

I agree. I was wanting him to try fuel in plug hole to see if bottom seal is blown if it wont even draw fuel dumped in carb in

 

[woodeneye]

Well now its backfiring... Haha!

 

[KG441c]

I would be looking at the flywheel side oil seal on that 026

 

[woodeneye]

Not the coil?

 

[KG441c]

Not the coil?

Id be betting on either a blown seal on either side of bottomend or bad intake boot or impulse line

 

[Wood Doctor]

Sounds like a MasterMind fix is in order. The saw is worth saving. I have an 026 Pro on board.

So, let's say it is the oil seal(s). What is it like to take them off on an 026? Can I just pop something through em, but a screw in and pry em out with pliers? Or is it more complicated than that. My stihl dealer is itchin to get his hand on this saw, but I like doing things myself, not to mention saving money.

A good compression gauge and a good pressure and vaccum unit would be invaluable if u plan on working on many saws.Maybe someone nearby u has one and could pressure and vaccum test it for u

Do u have the 026 service manual? Send me ur email in a pm

 

[woodeneye]

I don't know many saw fanatics besides dealers in my area. One member is near me, but he is more of a swapper and trader than a fixer , I think. I'll probably get a vac tester.

 

[woodeneye]

Yes, I have the service manual and IPL. I thought it said you needed a special tool for oil seals though...
