Re: Weber Carb Revisited
 

Hey Sleestak,

I have had trouble with my Weber in the past also. Did you buy yours new or
used? I had to rebuild mine(bought used) before I had mine running right.
Dirty passages caused my problems.

When you set up the idle speed, make sure the vacuum secondary is
disconnected from the carb and distributor and plugged on both. Then set the
idle to 450-500rpm. It should fall into the 700-900 rpm range with the vac
hoses hooked up.

For those who want to check on the Weber design, please read the
install/setup instruction on Weber's site for more info.

Luck, Brian

Thanks for the info Brian. I bought this carb new from www.carbs.net. I'll
try setting it up with the vacs plugged. btw, how far in do you run your
idle speed screw?

Thanks again.

You are worrying too much about what some $5.00 per hour sales drone
told you...

If you read the link above it tells you how to set up the carb.

I warns that the idle will be slow like a tractor at the 'base line'
setting of 1.5 turns in on the idle speed screw and you are to turn this
screw 'after' setting up the mix screw to get it up to 7 to 900 rpm for
a stable idle.

No 2 engines will have the same setting on the idle speed screw or they
wouldn't need a screw there to start with.

I see the identical carbs set up with wildly varying screw settings.
These settings change after a carb kit too.

That above site also tells you what jet size you need according to where
your mix screw sets.

This setting of the mix screw makes a radical difference in the idle
speed screw setting.

Thanks again Mike. I think you are absolutly correct, and I am going to
stop worrying about this idle screw business. Now for more important
matters, need to pick a gear ratio and lockers for the axles... 33x12.5
Dana44 rear, Dana 30 front, 258, t-5. Thinking of a Powertrax no-slip for
the rear, but can't decide on the front -- with 4.56 gears.
