Stihl 026 will not run.

[woody367]

I have a Stihl 026 that will not run. It ran but not good as fuel was left in it. I cleaned the carb and replaced the fuel line, filter and impulse line. Now it will not start at all. If I sprat fuel or starting fluid in carb it starts right up. So I bought 2 aftermarket carbs and 2 new sets of hoses in case I put a hole in . Still same issue no matter which carb is used. Anyone have any ideas? It is obviously not getting fuel. Thanks

OEM WT194 for the cure, AM junk is hit or miss, often miss.

I imagine you are right about fuel.

I always put a full OEM carb kit in the OEM carb before going with AM carb.

But, when I have ended up with AM carbs, they have mostly been fine. I have one on a 026 right now which runs tip-top.

If it was me...I would double check all not-fuel issues first (the free or low-cost ones). New spark plug, check for spark, look at piston through exhaust, compression check, do a P&V test of: the case, fuel line, and carb.

If all that checks out, I'd put a Walbro full kit in the original carb.

Thank you, I would try a rebuild kit but never worked on these small carbs. I can no longer do small detail work with my failing eyes. I might just have to buy a new one. I have the same issue with a ECHO blower and might just buy a new carb, not that I have the money.

Anyone know what the rebuild kit # is? I might try nit anyway, have nothing to losse.

 

[irhunter]

What model is the original carb? Those 026 came with a couple different models.

Make sure the fuel and pulse hoses aren’t blocked. I’ve seen aftermarket hoses that were plugged up due to poor quality molds/molding.

Same problem following throwing the kitchen sink at a 455 Rancher. It was the fuel intake hose; it was crimped, pinched off. I trimmed the ends, and turned it in its port, until it laid down low. Saw started on first pull. Used it today. After sitting dry under the Bench for 4 mths.

The correct kit is Walbro K20 -WAT

Service manual attached.

Pay attention to the gaskets and diaphragms in the carb when you pull it apart and the order they go in. There will be many parts left over in the kit.

There is a good diagram of the gasket and diaphragm order in the service manual.

How can you recommend a kit without knowing the carb model?

Because all the 026 carbs are in the IPL and they are all WT carbs. If you know differently speak up.

Just because it is a WT base doesn't mean that they take the same kit. As I recall some took the -10 kit and others the -20 kit.

Great. Check that out and get back to the OP so he knows for sure instead of whining about what you might recall.

Ok guys. After moving to NC and half my stuff in satorage for some reason the box with the carbs in it can not be found. I have the crate with every chain saw and psrt but no carbs. So I will just buy a new carb and be done with it. Now will the carn on a 026 and a MS260 be the same and id there only 1 model carb to get? Just asking as some have stated more then 1 model was used. Thank you

It depends on what version your 026 is. Later ones had compensating carbs. Older ones didn't. Put up a photo of the back side of the original air filter and the top rear of the gas tank with the AF cover off.

I would run the wt-194 carb and just plug that spot on the air filter if your model has it.

Sorry for all the BS. I found the OR carbs see attached photos. 1- is off the 026 and 1- off the MS260 pro. Not sure which is which. The #'s I found sre WTE529 and WT22a if they mean anything. My eye are not great for detail stuff anymore. Not sure if I should try rebuilding them or just buy new. Thank you

The WT-22 is off the 026. You can either attempt to rebuild it with an OEM kit (K10-WAT) or just replace it with a genuine WT-194.

 

[woody367]

And the other one for the MS260 pro?

The WT-22 is listed in the Walbro site as a carb for the 026. I couldn't find info on the WTE-529.
