CLEANING AND INSPECTION

The entire carburetor should be cleaned with a
general solvent and dried with compressed air be-
fore disassembly.

Carburetor body and jets should be cleaned in a
carburetor cleaner following manufacturer’s in-
structions.

15, Filter

Check for clogged filter. Clean or replace as re-
quired.

Check inlet needle tip condition. If worn, the inlet
needle and seat must be replaced as a matched
set.

NOTE:

Install needle valve for snowmobile carbu-

retor only. It is designed to operate with a fuel
pump system.

Check throttle slide for wear. Replace as neces-
sary.

Check idle speed screw straightness. Replace as
necessary.

Check for fuel soaked into float

no. 12

;

replace as

necessary.

Check float for cracks or other damages affecting

WARNING

Exercise care when handling throttle slide.
Scratches incurred may cause throttle slide
to stick open in operation.

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.

◆

WARNING

Solvent with a low flash point such as gaso-
line, naphtha, benzol, etc., should not be
used as they are flammable and explosive.
