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

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.

By hand replace with the new product . That young lady that help me to get my new product was fast to find it she did a GOOD JOB. Thank you .
