Echo 2511 tuning

[spudulike]

I reckon Matty is missing living 3 miles from me, I think the record was a buggered 357XP being dropped off around 8.00PM and being up and running for the next mornings work.

I sort of miss those days for the entertainment, piss taking and he always bunged me a tip.....always the sign of a gent!

That I do mate , posting saws isn’t quite the same.

Hi from the other side of the world! My dear little 2511 is getting more troublesome with age. It is leaning out spazmodically, and has been back and forth from the local chainsaw shop. Its never held a tune for a really long time, but seems to have gotten worse. Should I be looking for an air leak or is it more likely to be carb related?

[spudulike]

Fairly unlikely to be an air leak, more likely to be the carb. Get it set back to factory settings then tweak the L screw and idle for a decent ldle then adjust the H screw for around 13krpm then test. It may need a FULL carb kit and I say "FULL" meaning metering arm, spring, needle and the diaphragms.

Hey Spud, thanks for the reply, great to hear advice from a wizard such as yourself. I'm wondering if can upgrade to the newer version of the carb I think I've seen you talking about? I probably won't be able to source it in NZ but have a family member coming over in a few weeks, I could get stuff posted to them to bring out. Can you make any recommendations? Much appreciated.

I am not sure what the changes were from the old model to new. I have seen variable idle and issues when the saw is hung vertically from the strop clip. The vertical issue can be particularly irritating as I haven't found any real route cause.

New FULL carb kit including needle, spring and metering arm can help the wandering idle issue but be prepared to work at the H&L screws to get there. Start at the recommended factory settings then adapt them to your machine.

OP Hopefully you should find the Echo Service Manual  PDF attached.

Specs and procedure for setting are in there, it's the best place to start.

Thanks for the advice, I was hoping I'd be able to bring it up to the. New model spec and never look back! Between this saw and my 540xp (has been great for years, but giving me grief starting now) I just want to give up. Temperature is hanging around 30 degrees here though, which probably isn't helping.
