Question about Garden

1 Answer

I have a broken primer bulb for an Echo CS-3400 chainsaw. I need to replace it but am not sure how to remove the old bulb. I can access it but am not sure if it will be necessary to remove all the guts of the saw to get it out.

    Broken purge bulb. Easy to remove air filter cover but not at all obvious how to free it from the black ring holding it to the housing.

You should be able to get to it if you just take off the cover that surrounds it. If you do not yet have a bulb purchased, I would reccomend trying the site I have below. I have also put the part number you will need to enter in the 'Search' box on the site to get the right bulb.

web site:

Part #: ST-615-811

Echo Cs-400 chainsaw. Standing the carb up with the sliver vent on top which fuel line goes to the 90° inlet on the bottom and which line from the primer bulb to the carb?

The lengths of the line and,or the bends in the line . I would say the line from the bulb would go the carb since it is used to prime or,choke the carb.

Are you pumping the primer bulb until fuel flows into the bulb, setting the choke, and the fast idle is being set? Set the choke at half position after the first 'pop' and don't touch the throttle until it starts running. If you are doing these things per the instructions, take the machine back for warranty adjustment. Hope this helps!

How to replace primer bulb on small echo gas chain saw.

I just replaced the primer bulb on my Echo cs-305.
I didn't find the parts list too helpful.

It's easy. All you have to do is remove the air filter and look at the existing bulb from the bottom-- you can reach in with a screwdriver and pop the 'feet' holding it in place off their catches. When I put the new one in, I attached the tubes using a pair of needlenose pliers.
