If you have one of the rotary-type, non- adjustable carbs, you may have to install a diaghram kit or rebuild kit as the fuel pump diaghram may need may only need to "tweak" the H-speed adjustment screw on this carb. If so, here is how Zama says to do it:
The tool used to adjust these carbs can be found on Ebay and is less than $10 if you don't rig one by your own methods.
Here is an application list from Zama so you may know what diaghram and/or rebuild kit to install.
Here is a cross reference to the carb's kits:
RB is complete rebuild kit and GND is gasket and diaghram kit.

Remove the in tank fuel filter and take it apart, the felt Echo uses on the filter clogs quickly. There is still a mesh screen filter in the assembly so make sure you put it all back together and reinstall the fuel filter into the tank.

Echo pb 500t. Starts and idles OK. When I advance throttle, why does it die?

Hi Alex:
Odds are pretty good that the screen in the muffler is plugged with carbon. The back pressure will stop it from running.
My suggestion?
Remove the muffler. Clean all the bits in solvent and air blow dry.
Re-assemble and
Ta Da!

How to start Echo ppt-266

Fill with correct fuel/oil mix. turn switch to I. Pump primer bulb 4-5 times. Turn choke on. Pull starter until engine fires. Turn choke off. Pull Starter until engine runs & allow to warm up for 10 secs before trying to engage throttle. If it doesn't start after 3-4 pulls with no choke then try same sequence again. May have to use 1/2 choke after engine fires. If it still won't start then something is wrong with it & it will need to be checked by a service agent.

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
