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.

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
