I am not gettin my Echo CS-346 tuned like I want.
Once U remove them , Can U leave the caps off ????
That depends on the saw. You can if there are springs or some other method to prevent the needles from "self-adjusting" Otherwise, if your carb relies on the caps to provide friction, just shave the tabs off the caps and re-install.
I didn't see nuttin' ....
I was reading on another forum, about the caps on an echo 370, here is one reply
Jud...I looked around the shop and could not find a single carb with springs on the adjustment screws.
Over 100 Stihl, redmax,echo, commercial units. Most have been adjusted at some point and the caps ain't around.
I believe the screws have an interference thread because once they are adjusted, they stay adjusted.

Wadya think ?
Yah, so long as there is something to hold the screws in place, you can lose the caps.
had limiter caps on an old mcculloch i had , removed the jets / needles what ever you call them bugger of a job as thay where a mushroom shape on top with no screwdriver slot , once off cut a small slot in the top of them with a hacksaw blade , and put some small springs in place of the limiter caps i think the springs where off an old brushcutter carby , sounded realy sweet after doing that and just ran much smoother . cheers
