Two things which may be the problem: 1) carb need to be rebuilt or replaced, and 2) you need a new spark plug. The carb with shipping is around $50.00 from sears ( http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Grass-trimmer-weed-wacker-Parts/Model-3167918602008/0247/1503820/P0805032/00001?blt=06&prst=&shdMod= ) A sparkplug can be had at any small engine repair shop and most auto parts stores for less than $5.00 Start with the cheap solution... Also make certain you have fresh gas and that the oil mix is correct.

Go to the Sears URL page listed and click on the sears number you find on your string trimmer and see the exploded parts of that model.

fit a diaphragm kit in the carby
the pump diaphragm is the first to fail and then the float diaphragm distorts and will not let in enough fuel to keep it running

yes, there is a spark module, but it's highly unlikely that two would have a bad module - more than likely, it is your gas mix. it must be fresh for the engine to run. the gas we have today will go bad in about a month and a half. if you happen to live in an area that has E85, forget it. small engines will not run very long, if at all on this junk. in some areas, you can get gas without alcohol, but it can only be used for lawn & garden equipment. it's expensive, but your engines will run

Check the fuel lines for cracks/breaks. If they are o.k., then:

You willneed to disassemble the carburetor and spray with carb.cleaner. Makesure the small screen is free of debris.(Should be able to see daylightthrough it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance, just let me know.
