It sat for about a year from C&H's conversion until I ran it so I was wondering if it possibly had some "varnish" in the porting. I pulled the carb last night and everything is in good shape, installed correctly and clear. The 2000mAh battery is brand new and I've cycled it several times with good capacity. It runs great at the top end so fuel draw doesn't seem to be problem but metering does since it won't run at low throttle settings or idle. If it was running rough or lean I'd be suspicious of the ignition's strength but it is very smooth when running.
