To get the launch throttle response dialed in.
do your tuning with no vacuum advance at all.
get the initial base timing, centrifical curve and the total max mech timing
correct first. Then work in the amount and rate of vacuum advance.
The edelbrock carbs usually work best with a healthy dose of inital base timing.
24-26deg base at idle. 34-36 at max mechanical .
Limit the centrifical curve to around 10deg to allow this.
|Again the carb can be sensitive to where the PCV hose is connected to.
(front or back of the carb.) I recomend the back of the carb for the PCV.
Once you get this all tuned in you can get a fully adjustaBLE vacuum advance
and use ported vacuum as a signal source.
Stalling on hard turns.
The float setting is a starting point. You can fine tune from that as required.
and play with the fuel pressure a bit too. 5 to 6psi.
usually its cause the float is running slightly too high. or the fuel pressure
is a bit too high.
The fuel inlet needle-seat size also plays a role.
a a large needle seat assembly (.110"+) acts with more force on the float than a smaller one does. (='s less fuel control on turns)
there is also a off road spring leaded needle seat assembly for increase fuel
You can also convert the carb to dual fuel inlets ( right and left) and block the internal connecting fuel channel between the right and left bowls.
If your carb is the electric choke version
start your tuning using the default jetting of the manual choke version.
The calibration is a bit richer and will give better throttle response.
You can tune it from there.
