Echo Blower PB-403T will not start. I replaced the air filter, fuel filter and spark plug. The fuel line inside the gas tank had broken off at the top. I reconnected and it still will not start. Previously I cleaned the spark arrestor screen and checked the coil. Is it possible the coil is improperly spaced/gapped? Any ideas?

Should be two fuel lines coming from fuel tank grommet. One feeds the carb's primer plate and the other returns from the same. Open the fuel tank and observe while pressing the primer. If you see fuel pumped INTO the tank while pushing the primer and pulled FROM the tank when the primer is released, you're OK. If not, the lines are backward. Filtered line is on SUCTION side of primer bulb. Unfiltered line is on PRESSURE side of primer and is simply a return to the tank.
Next, concerning the coil: Air gap should be .010 inch at the magnet. Echo ignition coils are warrantied for life to the original purchaser, so don't tamper too much with it. Check gap and check fire with a spark tester. If no spark with switch in on position, take it to an AUTHORIZED SERVICING dealer, found here.

Hope this helps,

Echo pb 200 new carb, plug , filter , lines ,grommet starts and immediately dies


You might have the fuel lines crossed. Or a leak of air into the gas tank. It’s a fuel problem for sure if it starts and then dies.

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.

My echo pb-251 leaf blower won't start and sounds like a slight backfire - what is the likely cause?


Consider the flywheel. This model uses a flywheel with a built in key. If that key is bent or broken the timing would be off which would explain the backfire. You can source a replacement unit from eReplacement parts. Unfortunately the flywheel is 44 bucks and you have to be able to dismantle the unit to replace it. These blowers cost 200 dollars new. So you have a little wiggle room here. If the flywheel is good you may have a bad coil which can cause timing problems or weak spark. But those are 76 bucks so look at the flywheel first.

ECHO PB-500T - Stopped running and added gas fuel mix. Quit running again with full tank and now flywheel is stuck and I can't pull to start it. What is the problem?


My $350 Echo PB-500T seized up. I almost cried.

The solution was to drain the fuel tank.

  • Refill fuel tank with an 2-cycle Oli/gas mixture.

  • 40:1 =3.2 oz to one-gallon gas, do not use Alcohol base gas.

  • Remove the spark plug.

  • Pour approximate 1/8 oz 2-cycle Oli into the spark plug hole.

  • Remove the pull cord assembly (4-bolts)

  • This reviled the crank shaft-Pull cord bracket

  • I use a large monkey wrench to turn the shaft (CW) Clock-wise.

  • Complete approximate 20 revolutions.

  • Reassemble, but don't install the spark plug yet.

  • Complete approximate 20 more revolutions

    by pulling the pull cord.

  • Use q-tips to swab the top of the piston, as much as possible.

  • Install the spark-plug and crank, it will smoke for amount 7-10 minutes

I have a Echo PB-260L Blower. It starts fine then gradually loses power sometimes completely shutting off. I have replaced the fuel filter spark plug air filter and have cleaned the screen.


Check the exhaust port upstream from the muffler and make sure it is not restricted with carbon. Mine was less than half way covered over with carbon. Scraped out carbon, checked muffler and screen(ok), back-blow the fuel line harness including the fuel filter and fuel tank vent and took carb apart and blew out all passages, not replacing anything and now runs fine. Would not rev past high idle before. Be sure gas is FRESH and mixed at 40-50 to 1. Hope this helps.

Ho spark on a pb 403t backpack blower


Be sure you have no spark ( 90% of the units that come into my shop for repair with the complaint of no spark- have a fuel issue). Be sure the spark plug is good.
If no spark then remove the ground wire from the module and check for spark again. You must use the recoil starter- spinning by hand is not sufficient. If still no spark then replace module. If there is spark with the ground wire disconnected then there is a problem with the kill switch or a bad wire.
