NOTE: In the HYGRADE FINGERTIP CARBURETOR REBUILDING KIT you will find all the parts that need replacmg
in the carburetor you are working on. There are a number of parts in the carburetor which do not
wear and should be put back when rebuilding. Included in the HYGRADE Kit are all new gaskets, washers, springs, and jets. The smaller parts are packed in envelopes by assemblies. When you start
assembling, as you come to each section of the carburetor take out the envelope for that assembly and
lay the parts on the table in front of you. Compare these new parts with those you have taken off the
carburetor. Disca,rd the exact same, worn parts and rebuild the carburetor only with the new HYGRADE
parts. As a check on your own work, when you have finished any assembly operation you should have
no more parts left in that envelope. In re-assembling a carburetor it is most important that all tools
and parts, including the hands, be kept absolutely clean.
