Preliminary Carb Settings on Echo Weed Whacker?

[hotajax]

Echo SRM 225. Won't start up, going to start from scratch. How many turns out to start? 1? 1 1/4? Oh, b4 I forget, this is for a carb with one single adjustment screw. Thanks.

That carb is a rotary or barrel design. The one screw you see adjusts the idle speed. There are adjustments for the hi and low needles but they are not obvious. See

for helpful info on that type carb.

Surprised the EPA and FBI didn't come and arrest him. Thanks for the info.

I've never seen a 225 with only one adjustment needle. One is in the middle of the rotor, and the other is below the primer bulb.

My GT-200 and PB-250 both have this style carb. I unblocked the one near the bulb and richened it up a bit, they both run quite well. My Shindaiwa T242 is a mystery. It seems to have this style carb but I can't find any adjustments on it, even hidden under plugs.
