Carburetion problems that are not corrected by mixture
adjustments are usually a result of gummed-up fuel
passages or worn internal parts. The most effective
solution is a carburetor overhaul.
In general, overhauling a carburetor consists of disas-
sembly, a thorough cleaning, and replacement of worn
parts. Carburetor overhaul kits are available.
General instructions for overhauling a carburetor are
given below. Carefully notethe position of all parts while
removing to assure correct placement when reassemb-
ling. Read through all the instructions before beginning
for a better understanding of the procedures involved.
