Echo blower wont start after replacing air filter kit

air cleaner is clean? was rebuilt ? good spark plug? is there a air / fuel adjustment screw or a high / low idle screw on the side of carb. that may be out of adjustment? fuel lines are in good shape? (not cracked or broken sucking air in)?

Clean or replace carburetor.

Hi dbooth
Make sure your fuel lines are connected correctly.

I start with the screw about 1 1/2 turns out from fully seated (turned all the way in) but be careful when turning it all the way in not to turn it too hard as you can damage the end of the mixture screw. This should get you close enough to fine tune it.

I would start with checking and changing air filter, spark plugs, fuel filter and temp sending unit since that sensor is wat tells the comp it needs to be choked. Since you did not specify year I guess I will include if its carburated if it does have a carb its a choke issue if it has and mechanical temp choke (a coiled spring inside a casing) I would recomend replacing it with a cable or electric choke kit. If it already has an electric choke check wiring and replace if necessary. Also clean the carb and change the fuel filter may eeven just need a rebuild kit

Most likely there's a problem with fuel supply - choking cuts air supply optimizing the air/fuel mix. Most common solution is to check and clean the carburetor.

If there's a tiny fuel filter in the fuel line between tank and carburetor check it on excessive pollution. Replace it when necessary.

When opening the blower for carburetor cleaning - also check the airfilter and replace when dirty.

If never opened the blower - take pictures with a digital camera at each step. The pictures can help with assembly after cleaning.

Needs a carb kit the diaphram is dry

Did you relpace the inline fuel filter? they need replacing every year due to fuel addtive required by the feds. Try that first then the primer bulb check valve could have dirt in it with the air cleaner off look into the carb port and press the button three or four times, if you see no fuel then replace the filter first then pull the gas bulbp apart and clean.

Echo carbs have a little black plastic plug covering the High speed adj screw..CA air pulotion control bs..So get that little black blug out and give the screw a little turn open and u should be good to go..It worked for me..on a PBL 251 blower..My Echo weed wacker has the carb also..Go to Echos site and download the parts break down for your unit and look at the carb page..You will see the plug and HS,screw..happing wacking and blowing

have you tried to adjust the carb? screw all screws all the way in , then back out 1-1/2 turns then try to start it and tell me what happpens in detail, thanks.
