hi Bruce

I have a homelite st175...UT 20541

it starts beautifully, but when you squeeze the trigger it boggs down and dies, i have tried to ajust the 2 screws L H but they are plastiv and have some thought of fins( what i call them)
so you can only go a certain distance either way.
with either of the screws..
what is the procedure please bruce..

Ps
do you have the owners manual please i found the parts one but not the owners manual..

thabnk you

Frank
