Dual Weber IDF 40s, Carb Rookie question... Options

[malcolm2]

Hello everyone. I will preface by saying that this is an engine from a 914. (IMG:style_emoticons/default/piratenanner.gif)

But it is in my VW Bus. Just now getting it moving down the road. Everything is new.

Carbs are new and I am a carb rookie, as well. Bought them from Aircooled.net and had them cleaned and set-up for the bus. My 914 has L-Jet FI, this group has taught me enough about that system to be dangerous.

So here is my question for the carb experts. What should the Pump Valve spray look like? It seems erratic and drippy. It kicks in 1st as I open the throttle, not a spray but pore, really. I will say that I see that in all 4.

Sounds like they are not synced.
One cylinder sounds off, with valve noise also.

Even at revving it still sounds off.

I believe these are new carbs, you stated you just bought them?
Start with remove and verify all settings.
Sadly, they won’t be the same
Check and fix float level
Check and fix accel pump settings.

You should not see fuel at idle
Yes you will see the pumps squirt when you blip the throttle…they is their job
You should not see them at constant higher rpm’s ( to a point)

Get the book on how to tune webers.
Syncing them , once you get it right, will make the engine purr
