Small Engines (Lawn Mowers, etc.): echo backpack blower

Question
QUESTION: I have an Echo backpack blower that I need to constantly adjust the choke to keep it running and is getting worse and losing power.  I suspect I need to take the carb apart and soak it in cleaner to clear the jets, etc.  

Is there a carb rebuild kit for this device and suggestions as to where to buy?  Are there any gotchas I should be aware of or suggestions on cleaning/rebuilding this carb?

Thanks,
Ed

ANSWER: Yes, carb kits are readily available.  Yes, there are a few tricks.

If you have 2 fuel lines, MARK them before removing so you know which way to re-connect them.

Use a flashlight or remove the carb and let me know the carburetor brand (Zama, Walbro, Tilleston) along with the carburetor model and I will look up the kit.

The model number will be stamped on the carb, WA, WT or may C1U.

Let me know what carb you have.

QUESTION: Hi Eric,

I had to take the carb off to see the numbers.  It is a Walbro and there are some numbers stamped on the side and they are: 190 426.  There was also a couple letter on top of the casting: WYK.  Other than that, those were the only markings.

FYI, it's an Echo model PB-260L.  Are there any sites you can suggest that has an illustrated parts breakdown of all the components?

Thanks,
Ed
