Revisiting the Echo 280E | AKA Fuel Spitter

I have worked on and off with this chainsaw, but gave up a while back. It is spitting fuel like nobody's business. Why? Will a new carb kit help? Find out!

Small engine parts I use in the shop

Check that reed and see if it is seating properly . There should be no gap between the reed and black spacer . Do NOT BEND THE REED, If you do you done screwed the pooch . 1. Remove carb, 2. Remove the black reed spacer . Do not take the two screws out . Just remove the spacer with the reed for now . Any work done to carb and the spacer with Reed should be done on towl or at least paper towl . Check and look at the spacer and reed to see if there are any gaps between the metal reed and Spacer . If there is no gap and seating proper aginst the spacer then it is fine . 3 If there is any space between the reed and spacer then you will have to remove the reed from the spacer . 4. You should see a ring mark on the out side of the reed . 5. Inspect the spacer carefully . If see a line between the screw holes and the inlet that is where the problem is, 6, Used ether 1000 to 2000 grit sand paper laying flat on a super flat area . Counter top or glass . You want to sand that side until the line is gone . Make dam sure you sand on a perfectly flat serface, I also sand the other side of the black spacer 7. Reassemble .

I would look at the reed valves, may not be fully seating so when fuel\air is pushed into the cylinder some is coming back out of the carb, just a thought

Thanks, this helped me to fix my issues. Turned out that the first problem was that I didn't have the metering lever adjusted properly, after a carb rebuild. The second problem was that the fuel vent was plugged.

Reed Valves!!! Remember the rubber one way flaps on your carburetor? Reed valves do the same thing for the engine air / fuel intake.. If it is blowing anything out the intake the reed valves are not working properly and need inspection. They will be dirty or damaged..

It's the reed valve dude, it should be no gap. Undo 2 screws holding it in flip it 180 rebuild check for no gap. On suck it opens letting fuel mix in on compression it closes allowing full bang to happen. If flipping it doesn't work you got to very carefully bend it.

Hey is they supposed to be a check ball in both holes for the high low screws or Just one side ?

[larrymeldrum]

Just had same problem and something was caught in the Reed wasn't allowing it to fully close

[trottr]

check the black block behind the carb the plate on the back side should be flat to the block if not it will let it spit back through the carb

Is that chainsaw a 14"? And is it true you can use 14", 16", 17" on any chainsaw??

[lemans]

Tim do a cylinder leakage test, it will check the piston and ring, also the valve seats, etc. one other trick is to give it full throttle blank off the carb to stop the air, any crap on the carb will be drawn through, we used to do this trick on our 56 jag d type

Acts like a clogged spark arrestor screen.
