Weber conversion on 1.3 motor

So I bought a project, had a knock, needed an engine swap.
Unfortunatly I live in an area that requires DEQ testing, so I made it a
stock engine on the swap as to be able to pass inspection.

After ( three used carbs later) trying to get my Sami to run decent on the stock carb, (and all the plumbing that goes with) I got it thru DEQ checks and got it titled.
BUT it still ran crappy......

I put a Weber on it, and it hauls, idles nicely, great secondaries,
BUT ...... I got the carb on a used engine that I installed to replace the knocking engine my car had in it, so I had no instructions on what to do to make it run correctly.

I stripped all of the switches, vacume lines, regulators, heat sensors, fuel vapor cannister, everything including the EGR system. all I left was a vacume line to run the distributor advance. (got that info from Redline web-site)


What do I need to leave on the engine for it to run safely.
Does the EGR (or any other system) NEED to be hooked up?
(it does seem to smoke a little since I got it back together)

I know this is a common upgrade, so I figured someone will know what I need (or don't need) on the engine.
Also wondering if anyone has done a DEQ inspection with a weber carb,
and is there anything special to do to make it pass??? (need todo again in2010)

Thanks in advance for any input..............

BTW The headers and flowmaster is next.....

weber swap...

1. Remove and neatly tie back all of the wiring harness that connected to the Hitachi carb. Or just whack it off and tape up the ends then remove the ECM 'cause you don't need it!

2.The EGR holes can be plugged then the EGR reattached covering the plugged holes.

3. Remove all vacuum hoses and plug their ports. Attach the vacuum advance to the port on the side of the Weber next to the mounting plate. (You may have already done this... )

I hope this helps!
