QuestionQUESTION: I have a sears weedwacker 358.791010 I got a year ago and it sat in the garage. Now I got it out of the box and wanted to use it. I can get it started but it wants to stop when I pull on the trigger. It's passed its date so I would like to try and adjust the cartb myself, but don't know where it is located! I assume the air mix needs to be adjusted one way or the other after it is running but don't know how much to take apart to find it? can you help.Thanks Ken
ANSWER: Hello Ken:
>>Sorry for the Delay. I have been Unable to Answer Questions Due to Health Issues. Thanks for Understanding.

>>The Following is the Instruction File for Setting the Air Mixture Screws. Any Input is Appreciated. The Procedure is the Same for 1 or 2 Mixture Screws, Just Use the Instruction File and Skip Over the Section with the Missing Mixture Screw ( Usually the H Mixture Screw).
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air (L) and Main Air (H) Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Set the Throttle Full Open, Start the Engine.
>>Turn the Main Air (H) Mixture Screw Clockwise Until Proper Revs are Obtained. **Carefully Use your Finger and Move the Governor Arm to Rev the Engine (on Chainsaws and Trimmers Use the Trigger to Rev the Engine) Until you Reach Max RPMs (on Chainsaws and Trimmers, the RPMs are Not Set to MAX. Set to Max and then Reverse the Setting Screw 1/4 or 1/2 Turn. If the H Mixture Screw is Set too High; the Engine will be Starved for the Oil in the Gas and Damage the Piston and Jug/Cylinder) and the Engine is Running Proper at Full Throttle Up a Grade and for Chainsaws and Trimmers they Do Not Bog Down Under a Load. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs.**
>>Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air (L) Mixture Screw so there is No Hesitation when Rapidly Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****

QUESTION: I have those pictures in the owners manual. They do not show the carb. Also what would seem to be 2 adjustment points don't have a slot for a screw driver? and I don't know which one is for high and which one is for low.
Thanks
do you know who makes this weedeater for sears?
