GENERAL MAINTENANCE
CARBURETOR
See Fi gur e 11 for carburetor adjustme nt a nd ider . tification.
Fo r average use, the engir.e will operate satisf:wtorily wif1
the carburetor a:ljusted as it le ft the factor .y.
Jt may be necessary to re-adjust the "Low Speed N eedle
Valve" , Fig. 11, Hef. 2, d ue to altitude and climatic condi-
tions. n wa!:> au j u!:> L ed to approximately 1- 1-1 /4 tur ns open
ttt the fl),ctory. Turning countcrolock.vioc will allow the en -
gine to run richer.
The "ldle Adj us c ment S cr e w", Fig. 11, Ref. 3, when turned
to the right, or clockwis e, w ill i ncre(tse th e en gin e s pe ed .
~ecornmende d idle speed is 1500 rpm. NOTE: This ad -
justment must be made wi th ~he "Neutra l- Shift" l<nob out, or
in Lhe neulra l posi t ion. See Ref. 7, Fig ur es 6 a nd 7.
The "High S pee d Nee .clle Va lve ", Fig. 11, Ref. 1, has be en
set at the factory for best all around per f orm an ce, approxi-
:nately 1 - 1-1 /4 turn s ope n. Due to a l titude and climatic
conditions, it may be necessary to re- acl juf;t slightly. Tu !' n-
ing coun t e r clocl~'l'ise causes engine to run ri cher. Adjus l-
