Edelbrock Yamaha YZ/WR426 - Manual (Page 2)

Figure 4.
SPECIAL NOTE: Because the Edelbrock
is less prone to flooding, we have found
the hot start button to be unnecessary. If
so desired to use one, we recommend
using the TerryCable hot start kit
#HSS0001 for 01’-later models where the
hot start is built into the stock carb.
There is a fitting on the Edelbrock carbs
for this too be hooked up. For models
equipped with the external hot start
button the stock components may also
be used with a longer piece of hose.
10. Align carburetor as close to vertical as
possible and tighten manifold clamp.
11. Adjust pull cable until wide-open
throttle is achieved. Adjust return cable
to take up the slack. Note: When
throttle cables are adjusted properly,
there should be approx. 1/8” of free
play in the throttle.
12. After throttle cables have been
adjusted the handle bars should be
rotated from full right stop to full left
stop while opening and closing throttle
to ensure smooth operation. Also
check to make sure the cables do not
catch or bind on anything, i.e., hand
guards, stabilizers.
13. Secure clamp around air boot onto
back of carburetor.
14. Install remote idle cable into threaded
tab on top of carburetor. Refer to main
instruction for remote idle cable
installation and adjustment.
15. Install fuel tank and connect fuel line to
petcock and secure with remaining
pinch clamp. Turn fuel on and check
for leaks.
16. Open throttle 3-5 times to prime
accelerator pump. Do not open
throttle any more than 5 times as this
may flood engine!!
17. Once pump is primed, get motor to TDC
and kick through without opening
throttle. If Motor will not fire with a few
kicks, open idle cable ½ turn and
repeat starting process.
NOTE: If flooding occurs, slowly
open throttle to wide open and
hold. With throttle still open, hold
decompression lever and kick
motor through 5-10 times.
Release throttle and
decompression lever and
proceed with normal starting
procedure.
