Echo cs 362 rich iddle after full throttle

[kbessas]

Hello guys,

Fairly new here. I work at workshop in Greece and i am facing some weird stuff with an echo cs 362. Have done a full rebuild of the carb. Vacuum test to the check valves of the carb, they work great, mew spark plug, new fuel filter. Piston as far as i can see from exhaust side looks pretty clear. It starts iddles perfect at 3000 rpm. When i hit full throttle and then let it iddle, it drops rpm to 2200 like it has more fuel than it needs and then iddles back at 3000rpm as it was. It is pretty odd. My guess is either a small air leak or a weak spring in the metering leaver. I would appreciate if anyone had the same problem and has solved it to help me.

Thanks!!

I wish I knew, we learn something every day. It's better to repair and figure it out than buy a new one and forget... cause your struggle brings solutions.
