View Full Version : dies on full open choke?
04-03-2007, 05:45 PM
i have a couple craftsman string trimmers that start good but only run half way decent at half choke.even when warm if you pull the choke completely off the things will bog down and die.i know they are junk but i want to run them till they are dead then i will go get a stihl or echo.any ideas on this problem?

If you haven't yet, remove the screen from inside the muffler. When they clog it won't run. And of course, new plug and tune the carb.

has new plug.i just went out and took the muffler off and its a nice little box.its self comtained and just short of cutting it in half it doesnt come apart.it looked pretty clean actually.......

Were the x ports clean? Sounds like a carb rebuild or replacement is in order. Maybe time to look for that commercial unit?

The only thing left I can think of is a compression test, or possibly the coil.

Check your primer bulb for cracks.
