CLEANING AND INSPECTION
The entire carburetor should be cleaned with a
general solvent and dried with compressed air be-
fore disassembly.
CAUTION: Heavy duty carburetor cleaner may
be harmful to the float material and to the rub-
ber parts, O-rings, etc. Therefore, it is recom-
mended to remove those parts prior to cleaning.
Carburetor body and jets should be cleaned in a
carburetor cleaner following manufacturer’s in-
structions.
CARBURETOR FLOAT LEVEL
ADJUSTMENT
Correct fuel level in float chamber is vital toward
maximum engine efficiency. To check for correct
float level proceed as follows:
– Remove float bowl and gasket from carburetor.
– Make sure that float arm is symmetric-not dis-
tored.
With carburetor chamber up side down:
– Measure height H between bowl seat and the
top edge of float arm. Use float level gauge (P/N
529 035 520).
– Keep float level gauge perfectly vertical and in line
with main jet hole.
Ensure that both float level gauge tips are properly
positioned on carburetor body and that “L” arm is
leaning on float without compressing valve spring.
Refer to following photos for proper float level
gauge positioning.
