Synchronizing the Carburetors
Some TVT / VTX / OV691 series use twin carburetors,
which MUST be synchronized if the linkage or carburetor
body has been disturbed. The following step by step
procedures must be followed to synchronize both
the throttle and choke. Inspect all link connectors. If
excessively worn or damaged replace them. To perform
this service the carburetors must be mounted and all
linkage must be connected.
1. Remove the control assembly cover, air cleaner
cover, air cleaner, carburetor deflector and air
cleaner body from the engine (diag. 73).
2. Remove the link connector bushing clip holding the
throttle link to the #1 cylinder carburetor (diag. 74).
3. Manually rotate the throttle shaft on the number #2
carburetor to the idle position. Next back out the idle
R.P.M. adjustment screw until it no longer contacts
the throttle plate tang (diag. 75).
4. While holding the number #2 carburetor throttle
shaft in the idle position turn in the idle R.P.M.
adjustment screw to 1/4 turn past first contact.
NOTE
It is critical to find first contact of the R.P.M. adjustment
screw to the throttle plate tang.
5. With the bushing clip still detached, back out the
idle R.P.M. adjustment screw on the #1 carburetor.
Hold the throttle plate in the idle position and turn
the idle R.P.M. adjustment screw in until first contact
with the tang is made (diag. 76).
