How do I remove the air cleaner case?
James for model number Pb-251
Hello James, Thanks for the question! Remove the air filter cover. (held in place with 2x knobs top and bottom) Remove the air filter. Remove the screws that secure the case. Separate the case from the carburetor gasket. We hope this helps!
I found my blower pb-251 does not run at all after I cleaned the carburetor. I purchased new carburetor, installed it, and then , still not running, May you help me with any suggestion?
Chris for model number pb-251
Hello Chris and thank you for writing. We suggest to check the following for replacement; Fuel Filter- A369000480 Spark Plug- 15901019830 Fuel Tank Vent- A356000031 These parts all contribute to the start of the machine. We recommend checking the above with trial and error to pin point the cause of the issue. Hope this helps!
Hello again I did what you recommended me by checking the Fuel Filter, Spark Plug and Fuel Tank Vent, but the blower still does not run.
Chris for model number pb-251 blower
Hi Greg, this could be caused by a variety of issues. 1.Airflow Issues, check the air filter to ensure that it's not clogged with dirt and debris. 2..Carburetor Adjustment,A carburetor that's incorrectly adjusted is a common cause of poor engine idling that results in hunting and surging. 3.Fuel Problems, If the fuel has been left in the mower while it was stored over the winter or while the mower has remained unused, drain it and replace it with fresh fuel. Thank you for your question and good luck with your repair!

Question: Mostly No Start

bhdntn

also have 25 string trimmer--- 1st pb - flip a coin to see if it will start, runs great when it does start has 90 oct. gas with echo oil fresh no ethonal gas - primer bulb does not firm up very well # 2 250 string trimmer (both carbs are not adjustable) finally got to run by remove hi speed adj and clean out stopped up having trouble on adj so that unit will idle runs hi speed but will not idle have put ovhal kit in carb as well as cleaned soak carb body in cleaner I have 25 yrs as a fact. trained mech on 2 cycle Mercury Marine
Hello bhdntn Those doggone Echos can be finnicky can't they? If everything on them is not JUST SO, a no start can and will result. I do not recommend soaking the carb however. The CHECK VALVES are sensitive and can swell, causing problems. I always just clean NOW with WD 40. No strong solvents and no high PSI compressed air. I do however add about 1/2 oz. of fuel system cleaner in a 1/2 gallon mix of fuel, to help clean. The cleaner I prefer has acetone in it. Many tout how great Sea Foam is, but Sea Foam won't put their list of ingredients on the can! It is also overpriced. Diaphragm carbs are very fragile actually. Not sure if there is anything else I can cover that you might have missed. The little Purge/Primer bulb doesn't have to be full for the carb to operate correctly. Some THINK it primes the engine with fuel. Of course, it does not.
Question: Echo PB 251 Starting

1136456

Lately, I am only able to start my PB 251 blower by NOT using either the choke or primer. Gas seems to be flooding into the engine when sitting unused. Often have to clear a flooding situation that prevents turning over the engine using the starter rope.

Blower is used at least weekly.

What could be causing this and what options ?


Thankyou
WJA

Question: Starts But Runs For Only 5 Secon...

Echo BB-251 starts fine and runs but only for about 5 seconds. What is most likely cause? Fuel filter, Gas line or Carburetor?

It sounds like you may have a dirty or clogged carburetor. You may want to use the O005001670 carburetor repair kit. But before that, watch the article and video we have prepared on. How to Clean a 2 cycle Engine Carburetor.

Hope this helps,
