Weber question
 

I finally got around to installing the Weber, but I
don't have any paperwork on it - the original
setup (Carter) has a fuel supply line coming from the fuel
pump to a filter. The filter has two lines coming out
of it, I assume one is a return to the gas tank.
The fuel line that came on the Weber is just a single
line from the fuel pump, what should I do with the
return line? Reuse the 2-outlet filter?

Re: Weber question
 

The return line is needed to prevent vapor lock on hot days. It also
gives the fuel pump a bit of relief.

Just remember to use the center outlet for the carb and have the return
line at the top so gas doesn't syphon back to the tank when the engine
is off.

You now need to put the computer to sleep or it will just stay in limp
home mode.

Thanks Mike, I already did the Nutter,
Just had too many lines for this new carb.
I've got plenty of vac lines to pull/plug now!

Hey, one more question - The Weber came with an adjustable
fuel pressure regulator, should I use it or just let the return line
handle the pressure? I'm thinking I should still use it, I hear the
Weber doesn't like higher pressure (although a stock pump
is probably not very high)

Someone posted a good link the other day on how to set up the Weber. I

Re: Weber question
 

I was told the stock fuel filter regulates the pressure to around 5
psi. This is a bit high for the Weber for some folks.

The pressure is controlled by the size of the hole in the filter's
return line nipple. It is a metered hole that could be drilled out to
lower the pressure.

But if you have the regulator, then I would put it in.

Re: Weber question
 

I have a Weber on my 258 and love it, although it was a bear to set up but
once done it runs great. I have headers and had to go with a .80 idle jet.
Now it will idle at aprox 750-800 Rpm when warm. My throttle plate is not
opened at all and the idle screw is not in contact with the throttle lever.
I had constant vacuum on the advance port causing me not to have any
advance, the jet change and timing adjustment fixed that. My timing is now
set to 9-10deg at 1600 rpm, the advance works great. I also have removed
most of the vacuum lines under the hood, all that is left is the front axle,
advance, pvc, master cylinder for the brakes. I had to put a fuel pressure
regulator on and adjust to 3.5 psi because it would run real rich with the
stock fuel pressure. I am using the stock filter center going to the carb
top going to the tank. The big float bowl vent is going to the canister,
with no purge line hooked up. I also did the HEI upgrade which helps with
the idle and adds some power off the line.

Re: Weber question
 

Heh, I think you are the second person to mention they have the timing
set at 1600 rpm for the computer controls with the computer in limp home
mode or not existing.

Do you still have your computer in the loop?

My 86 sets up with the timing at 9 deg at idle with the ported vacuum
line off the distributor and no computer. I have set several others up
like mine as well.

Re: Weber question
 

Heh, I think you are the second person to mention they have the timing
set at 1600 rpm for the computer controls with the computer in limp home
mode or not existing.

Do you still have your computer in the loop?

My 86 sets up with the timing at 9 deg at idle with the ported vacuum
line off the distributor and no computer. I have set several others up
like mine as well.

Re: Weber question
 

No Mike computer and all associated wiring is in the trash. I set the timing
with the advance off, I did it by ear got the best idle, took it for a ride
to see if it pinged, then I put the light on it and if I remember right it
is about 9 deg at 1600 been awhile since I did it though.
