its a Walbro WA-22A. Also I did see fuel up top in the "air box"? Where the carb mounts and such. Is that normal?

 

[mixemlewis]

Thanks bud

No, that is a problem. Goes back to the inlet needle not seating, the fuel hose leaking, or the carb gaskets are leaking. Some people say they can't get a carb to seal unless they wet the gaskets with fuel. You will have some spit back but it shouldn't pool.

 

[mixemlewis]

Ok great info thanks a lot. The kicker is though, that even before I tore into this saw and did the carb rebuild and restored the saw it was doing the same thing. Is it possible that the plastic reeds have something to do with this?

 

[mixemlewis]

Its sounding more and more like a problem with the inlet needle

 

[dsell]

The reeds are not causing fuel to leak into your air box.

 

[mixemlewis]

Ok. I will check the carb t/n and try to get some pictures

 

[dsell]

Someone said use baking soda on the end of a Qtip to restore the needle seat. I've never tried it.

 

[mixemlewis]

hmm. Thinkin its gummed up? I soaked everything in carb cleaner pretty good and blew it out.

First off, don't check for spark on a flooded saw as mentioned before, unless you like a flamethrower being shot at your face!!!

 

[mixemlewis]

haha yea thats a good point

 

[HarleyT]

Next, dump out all of the fuel, and remove the plug from the saw. Take the saw outside and pull the rope a few dozen times, see if you see any gas coming out of the plug hole. Then let the saw air dry for an hour or so, pull the rope some every now and again.

I will check the inlet needle later t/n and make sure its not stuck. Thats what it sounds like is going on

Is the tank gummed up? If so, you'll be cleaning the carb everytime you want to use the saw. I had that problem on a Homelite EZ and finally had to dip the entire tank in carb cleaner.

 

[mixemlewis]

Ok, will also dump the tank

 

[mixemlewis]

I wouldnt say it is. I sprayed it down pretty liberally with carb cleaner and let it soak before removing

 

[HarleyT]

Now, after you are sure that the saw is completely dry, put a new plug in, hook on the plug wire, and pull the rope a dozen more tries, try to get it to start/fire. Put no gas in the saw at all. If it finally starts, then dies, then you had a flooded saw, and go from there. If it doesn't fire at all, and the saw/tank is still dry, put a shot of carb spray into the throat of the carb, and try again to get it to start then die.
If it won't, then you likely have other problems as well, as an otherwise healthy saw will fire then die with
a prime/shot of carb cleaner.

 

[mixemlewis]

Ok sounds good. Will give that a shot. Just carb cleaner? Or is it ok to use a bit of gas in a spray bottle?
