Please see an old thread of mine here
I'm still having similar issues.
I've switched to using Amsoil Saber blended at 50:1, and I'm using LCD FP3000 in my OPE fuel along with Sta-bil. My OPE fuel is now Shell V-Power 91 which is ethanol-free (according to the sticker) but still 91 AKI as spare for the car.
I've adjusted the hidden mixture adjustment but it's still tough to start, and four strokes a lot at anything less than 2/3 throttle. If I lean it out to stop the four stroking, then I start getting lean starvation and no throttle response.
Fresh plug, air filter, fuel filter this year.
It is a 2003 Echo SRM-210 s/n 07002514. I believe that this means I have factory carb RB-K66B. I don't know that the initial helpful advice on carb replacement applies or not.
Depending on the cost, I'd love the option of getting a non-EPA carb with adjustments. I'm in Canada so it's legal, and it's legal for you to tell me
I've done a nearly full disassembly and engine cleaning again. The Saber has helped somewhat but I'd still like better. I continue to see lawn guys in the area with Echos and other brands that start on a half pull and idle smooth ("rrrrrrrrrrrrrr"). Mine jumps around and sounds like it has racing cams at the best of times.
Still, warmed up it has good power and response and WOT it's a monster.
I can start it "reliably" by doing the following:
- prime 5+ times after seeing fuel
- set full choke
- pull up to 4 times, if no catch at all go WOT
- pull up to 4 times - it should have at least sputtered
- immediately following sputter, choke open, no throttle
- pull and it'll sputter again and maybe run until you...
- choke to half, half throttle, it'll catch
- warm up a bit on half choke, no throttle on the ground or it'll stall.
- open choke, start trimming - missing, four stroking and all
Warm restarts are usually one pull, no choke, no throttle.
Any comments are welcome.
