Echo PPT-260 Telescoping Chain Saw SN 06005889
Echo PE-200 Edger SN 05003849
I have two Echo two-cycle engines doing the same thing. They start fine and idle fine. But when I throttle the engine up, both die. I can get the chain saw to somewhat work by closing the choke about 80%, but as soon as I turn the choke off and rev the engine, it dies.
They both have Zama Carbs. There are no High-Low needles on these carbs. Rather than a throttle plate, they both have a black plastic “rotor” with a hole in the middle that rotates to regulate the amount of air.
I’ve replaced the fuel lines and fuel filters on both. I replaced the two carb to engine gaskets on the Edger with OEM parts. I purchased a new non-oem carb for the edger and the new carb does the same thing as the old carb.
I took the Chainsaw carb apart and cleaned it. The gaskets looked fine so I did not replace them.
I’m perplexed as to why both have identical problems. I’m missing something. Any ideas?
Thanks
