44) Primer Button
Pull and push button. It is not necessary when engine is warm.
To prime, activate button until a pumping resistance is felt. From
this point, pump 2 or 3 times to inject fuel in intake manifold. After
priming, ensure that primer button is pushed back.
NOTE: In very cold temperature, it is recommended to rotate primer
button 3-4 turns prior to pull it. This will eliminate the possibility of
sticking.
