Question: Piston Assembly
When I separated the carb parts, the spring fell away but I can't tell if the piston is still in that section/hole or if I have lost it. Should the piston slide out easily or not?

The part number 12318539130 has an o-ring that holds it in. I would think it would take a good hit to get it out of there. If you can look up there and see a brass part I would say it is still in there.
Question: Leaf Blower Starter Pawl
Pull cord was stuck, thought it may be caught up on something. I removed the casing from blower and cord pulls fine, however the starter pawl does not spin. Before I take it to a shop to be checked out....anybody have any ideas on how bad this is?? Thanks.
Question: Starter Pawl Assembly
How do i get the old stater pawl off ??? its on a bolt, but the the whole thing spins freely.

To get the starter prawl off, take the appropriate sized socket and put it on an impact wrench. This will eliminate the need to use a piston stop or packing the cylinder with rope (which can cause major damage).
Question: Hard To Start
I was using my blower and it was working fine then all of a sudden it turned off. From this point on I am having a hard time getting it to run and when I do it will not run long.
Reply: Hard To Start
Your blower is probably hard to start because of compression loss. If it starts and runs then Dies after a bit this means the rings piston and or cylinder are scored or scratched because of not enough oil in the gas or poor air filtration. If none of those components are scratched up your rings or piston might need replacing. What happens is when it does start when it warms up the cylinder expands from heat and the ring don't expand with it causing loss of compression and thus shutting down the engine.
Question: Fuel To Cylinder
Is the flywheel key on my PB500 made of steel or is it designed to shear? I have spark to the plug but cannot even get it to cough, spit, or pop, even on ether. After 30 years of working on gas engines I have found one I cannot get to run. Do you have any ideas? Thanks in advance.

Hi George, I found the flywheel and key on page I --part 16 (above). It is listed as a Woodruff key. Aren't they made of steel. I guess they could be made of aluminum like on a B&S machine. Your question is a puzzle to me too. I love a challenge and own 2 echo machines myself. It sparks well but won't run! (not being sarcastic here; I'm with you). I am maybe leaning towards a timing issue too unless the compression is so bad that it won't go. It has to be rather high to run with these engines. Have you done a compression check? Maybe it has a broken ring(s).
Question: Echo PB-500H Blower
I bought it new last year, has been running great until a few weeks ago. Its tough to start and doesn't accelerate properly, with the choke in "run", it stalls. Ive changed the air filter, fuel filter, and plug. I was going to check the gas/oil mixture also just to be sure.
I'm not sure what else it could be other than the carburetor being clogged or something. Any ideas before I rip it apart? Is there an adjustment other than the idle I could try? The manual mentions a fuel vent, not sure where/what that is.
Thanks in advance for any help !

sound like your ignition coil is going out & or weak. worth checking out before you spend a lot of money guessing.

Sounds like a carburetor issue, I have serviced hundreds of these engine types this summer and never once had a recoil issue. Just take the carb completely apart and soak it in carb cleaning over night. Make sure you don't soak any rubber, gaskets or soft plastic (certain plastics can't be removed so you can go ahead and soak those, I've never had a problem). Then blow the whole thing out with dry compressed air. Make sure you use all the proper PPE (safety glasses, face shield and gloves).
That should do the trick!
