Small Engines (Lawn Mowers, etc.): Carb 6.5/5.0, varnish, carbs

Question
Ihave three different briggs motors with basically the same carbs.  They sat all year and I have pulled them off to clean them.  I have soaked them all in parts dip and made sure that all of the jets and floats are clean.  I am not able to get two of them to work.  The one that is working I have been able to run the other two motors with.  My question is this. Is there some where in the carb body not visible to me that I am missing and if so where is it and how do I clean it Thanks Barry

Answer
 Hello Barry:

 Did you use High Pressure Air to Blow the Ports and Passages out? The varnish in some Carbs can take up to 4 dips in Parts Cleaner before you get it out. Soak at least 12hrs Min. Hope this Helps.

 Good Luck

 Respectfully
