echo

I have echo pb251. It's 2yrs old. I registered it but don't have receipt. Recently it starts and idles fine. When I press the throttle it bogs down. I replaced air and fuel filter, changed spark plug and new fresh gas mix but still no luck. Thoughts? Do I need receipt for warranty?

Have you cleaned the spark arrestor and exhaust port. These are typical symtoms of blocked exhaust flow.

I guess that meant you threw the screen away? Now get onto the high needle and adjust it a little CCW. The high needle is the one furthest away from the engine.

We had the same symptoms and ended up putting on a new carb. Good luck.

If it doesn't have carb adjustment screws, do a search on Echo carb adjustment. Sounds like the high speed needs to be opened a little.

Yes...he didn't tell us what model he has. I will bet that 90% of the problems people have with echo trimmers can be fixed with adjusting the hidden needles.

hate to hijack but i have (had) the same problem on my ppf210 echo power prunner. after searching on here i found the high fuel plug, took it out, took the needle out, cleaned it, and adjusted it while running. works great at full throttle again. it still runs funny at idle to 1/2 throttle. where is the low fuel adjustment? someone said its on the rotor (top black throttleblade piece?). i don't see a plug or something that can be adjusted there. this board is very helpful. thanks again.
