Flooding walbro carb from blower.

i think walbro is a better carb. nikki is ok but just dont like them. it should be ok. why dont you just put a rebuild kit in the one you have? that is only $10.00 or $12.00

You need to pressure test the carb, if the needle is leaking you will never get to run well, if you have fitted a new rubber tipped needle and it still leaks you will have to replace the carb, the later carb was a Zama rather than the Walbro, it made the saw run so much better.

the needle valve in the carb is not seating change the needle valve and seat also check the oil when this happens gas drains into the crankcase if so you will need to change that as well

Get a rebuild kit for your carb most likely a walbro carb.

If you clean the dirt off the carb, the series no. and model no. will be etched into the body of the carb by the fuel inlet nozzel.

Please find above a couple of links for carb kits to fix your carb

You need to know if it is a walbro or a zama carb. to start with.
then look closely at the carb. and find #`s
very small

walbro will be wt or wa then some #`s
zama will be c1q or c1u and some #`s on the opposite side of carb.
Walbro will be on the same side

you need to know the carb. #`s so a kit can be found for that particular carb. IE: complete kit or diaphram kit

I am sorry to say this, but the compression for that type of engine should be atleast 120 psi. Remove the muffler and look at the cylinder, it is scarred beyond repair.

The most likely possibility is that the carb needs rebuilding. Just cleaning may not help. Gasgets go bad over time if fuel is left in the trimmer.

The solution to the fuel starvation problem with the Echo 8000 is based on the metering diaphragm. In late 2007, Walbro sold off a huge amount of carb kits which were not ethanol compliant. These kits were purchased by resellers like Stens. Now that many states have ethanol blended gasoline, the metering diaphragm dissolves and hardens in the presence of the added ethanol. You will need the walbro carb kit with a 'new' metering diaphragm that is not sensitive to alcohol or mtbe which is the summer fuel additive also in alot of areas. Each kit comes with a date on the package, use Walbro K22-HDA manufactured after 06-2008. I run these saws that is how I know.
