Engine would start and then stop after a short run.
took old cap off and put new cap on. Changing cap was a breeze.
Most time was used determining that the air bleeder in the original cap was not letting air into the fuel tank.

Carburetor Repair Kit - 530069811
Repair Difficulty:
Easy
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Small pick,carburator cleaner,air blower
carburator was glazed from old gas.
The carburetor on a craftsman leaf blower that was given to me had gas left in it and dried inside the carburetor creating a sticky glaze and causing the the ports and and the needle valve and float to stick. Removed the phillips screws from top and bottom of the carb removed float by removing the small Philips head retaining screw that holds the pin down for the needle valve .took carb cleaner sprayed down the hole carb being sure to clean out all the ports inside the carb and also used an air blow gun to blow them out. Also replaced the small screen inside the carb. Whenever you rebuild small carbs like these save yourself the hassle of taking it apart again to replace that screen and replace it while your at that point . Its not worth it taking a shortcut thinking your saving time. Used the carb rebuild kit I ordered from Ereplacementparts .com worked perfect put the carb back together and the blower was back in action. Took about a half hour to an hour to complete repairs. Keep in mind I have done so many of these small carbs I can do them in my sleep so for those who have had little experience doin this it may take a little longer. But it is very simple main thing is to make sure to clean the inside of the carb thoroughly and make sure all the ports are clean. They also sell a small set of nylon brushes you can get to clean the ports the brushes range from 1/4 inch all the way down to basically micro-scopic for those tiny ports inside these carbs.
Thanks Jim

    stalling problem corrected
    My poulan pole saw would stall and was hard to start. By replacing the cap, air could enter the fuel tank and relieve vacuum thus allowing fuel to continue flowing to carburetor. I purchase from ereplacement when my local dealer does not have part. Ereplacement has consistently delivered the part quicker than the dealer and at a competitive price.

    Need a part, no problem
    I was amazed at the website. I cannot imagine how many parts are in the warehouse. Finding your part is quick and easy.It is admirable that there pictures of the parts. Instruction videos are invaluable. Even though the parts I ordered for the weed whacked did not fix the problem of the machine not working,I will try some other part.
