Question i have a Poulan T & E 450 yr. 2000 weed trimmer that is sometimes difficult to start. i started ok last two times but today..no luck. i don't use it every week. it has a throttle screw and a L/H screw adjustment. i have made several turns of each so it is probably out of adjustment as i really don't know what i am doing. any advice on setting it right will be appreciated. no work ever done on trimmer.
thanks, joe
Answer Hi Joe,
The high speed mixture screw is initially set at 1&1/2 turns out. Then adjust it to give good acceleration and top speed while keeping the screw as far out as possible. The low speed mixture screw is set at 3/4 turn out, then adjust to give a smooth idle. The problem is most likely dirt or gummed fuel in the carb. You may need to clean it out and add a rebuild kit. Trimmers are hard to repair and unless new or of commercial quality it's best to replace them.
