Important Service
Information
Weber Carburetor Adjustable
Accelerator Pump
The accelerator pump lever on Weber Carburetors
has three holes in it. The closest hole to the lever’s
pivot point is the richest, the second hole is leaner
and the hole furthest away is the leanest. All produc-
tion carbs have the pump rod installed in the closest
(richest) hole. If you are having a “rich” bog on accel-
eration, move the rod to the second or third hole.
Weber put the three holes in the lever so the amount
of fuel delivered by the accelerator pump could be
changed.

Hard Starting
If a hard starting condition exists, after engine has not
been operated for a period of time, proceed with the
following:
1. Before starting engine, remove flame arrestor
then operate throttle to see if choke closes.
2. If choke is stuck open, check choke stove link rod
and choke linkage on both sides of carburetor for
cause of sticking. Possible paint or interference
to rod or linkage.
3. If choke plate does not close tight step 2 or 3, then
choke link rod will have to be bent to make it
shorter so it will close choke plate completely.

travel.
