Which is the better carburetor ?
This is why I ask:
Echo SRM-266S = Zama RB-K89
Echo SRM-2620 = Walbro WYC-9
Both are 25.4 cc trimmers.
Both have sold steel drive shafts.
SRM-2620 is the newer model.

bgsengine wrote:The SRM-2620 is more powerful and lighter in weight (about a pound lighter) than the SRM-266, yes - also with the gearbox re-design . SRM-2620 trimmer has more torque as well.
But as noted I'd rather have seen the 2620 come with Zama carburetor..
weight savings and durability - flex shaft is a little more forgiving of sudden load and torque changes, lighter weight as well, you'll be less likely to experience vibration and flex shaft will run cooler.Merkava_4 wrote:bgsengine, why did Echo go with a flex shaft instead of a solid steel drive shaft in the SRM-2620 ?
