Question about Echo Gas Blower 135 MPH390 CFM Blower PB250

Open Question

I did a tune up on my pb-250 echo blower changed the plug changed the fuel filter and air filter primed it cold started it switched it to run while holding down the throttle and it runs for about a minute, then it wants to stall out. I repated the procedure and this time i loosened the bleeder screw till a little bit of fuel came out and it started to rev faster but once i tighten it it wanted to stall?

SOURCE: Echo backpack blower stops after 20 minutes

Make sure the fuel tank cap inlet valve is working properly, this will allow a vapor lock if it is not. Then check the fuel line in tank to make sure the pickup filter is not hung up in tank thereby allowing the fuel to get below the pickup. Also check the fuel line for holes. You can also try customer care, manuals and parts, type in model no. then get owners manual and see if in troubleshooting section it list this problem.

SOURCE: echo gas leaf blower bog down

Likely dirt in high speed needle valve(H); could be leaky fuel line(air leaking in), plugged fuel filter, pinched fuel line, etc - anything restricting flow of fuel. Likely, you aggravated an existing problem by cleaning the air filter which would have been providing some choke effect if it were partially plugged.

you can thank the EPA for your blower problem the EPA makes all brands of lawn equipent "tamper proof" with plugs and limit caps. not just echo......when we service an echo piece of equipment we let it "break" in and adj the carb as needed BEFORE it leaves my shop. dont hesitate to bring it back to the dealer, if they are reputable, they will do the adj while you wait......hope this helps. good luck

SOURCE: We just bought an echo pb 250 leaf blower and

sounds like its not getting gas in the carberator yet. even though its new i would take off the air breather and pour a small amount of gas in airtake. this might get it started enough to prime the carberator and draw the gas on its own.

Echo PB 251 won't run. replaced plug, gas, fuel filter, air filter. took carb a part, and cleaned with carb cleaner, used the compressed cleaner to clean out venturis/ports.

Wow! with all you have done it should run. Be sure the switch is on but if you are getting spark, it should be on. I would take it to the echo place for service.

Echo PB 200- finally got it running right, sounded great. Pulling fuel and priming pretty easy. Let it run and then shut it off to put air filter back on it. Now it won't start. I was getting inconsistent...

My Echo PB-251 will not start.

I know you checked the plug, but it can fire outside the cylinder and then not fire under compression.
If you have compression, fuel, and spark at the right time you should get combustion.

My Echo Leaf Blower (PB-251) will not run at high speed. It is running to rich. Help please. Charlie

I've been fighting with an Echo PB-251 blower and an Echo SRM-225 string trimmer since near the end of last lawn season (this is the forth season I've had them). Along comes a thread on a firearms forum and lo and behold the answer to the problem is spelled out in terms even I can understand.

After reading that thread (which attributes the problem of the engine bogging down when throttle is activated to collapsing fuel lines) I was going to just replace the fuel lines, but I discovered that there are kits that include new fuel lines, rubber grommets, filters, clips and cap seals for about $13.00 each. Hell, the kit for the SRM-225 even provided a new primer bulb. Ten minutes after the UPS truck delivered them to my door I had both machines running like new again. If you've tried other things and it still hasn't worked I highly suggest you try this.
