New Weber Installed..Questions

OK, UPS shows my new Weber to be delivered today! Can't wait to get home. Anything special I should think of, or need to buy? Is it as easy as unbolting the old carb, and bolting in the new?..then the normal adjustments of course.

Also, do I have to hookup the electric choke now, or can it wait? I remembered a post which says to hook it up to the wire going to the horn.

Hog it Out!

Now guys, talk to me about the heat shield..do I have to cut it out (the holes), or will it work as is and not interfere with the butterflies?

Nothing disrupts air flow like thin plates sticking out into the inlet tract!
Just grind the hole out to at least the size of the bottom of the carb throats and while you are about it look at the inlet manifold under there to as, standard the flange is smaller than the Weber - especially on the secondary (larger) throat. Just make sure grindy bits don't get down into the manifold.
Best done when the manifolds are off the engine and can be rigourously cleaned - so I hope you have not redone the head to manifold gasket yet.

More info on that is in the Legere article on intakes. If its not here in the archives it is at the http://www.opel-na.com website in the tech library.

If you're pulling the intake it's a great time to port the intake. Hardest part will be removing the intake from the exhaust. Even then, you could do it attached to the exhaust if you removed the intake from the head, and blocked the holes in the head while you worked on the intake. Will leave a lot of little AL bits in the engine bay though. Clean them up before you put everything together.

Optimally you would put it on a bench to do the work.

Weber carb.

bozkm;
As for the fuel inlet, you can unscrew the one on there, unscrew the cap on the opposite side and swap them. That way the inlet nipple is pointed away from the valve cover. This is one of the nice things about a weber. As for the hard starting and such, I'd make sure all your timing marks are aligned correctly. My sister's GT ran great, when she first got it, then switching to a weber, I found it used to have the A.I.R. pump and the PO didn't seal up the nozzles correctly and had to advance the timing to compensate for the extra air. So after correctly plugging all the leaks, and adjusting, the car ran well enough to scare the sh*t out of her.

Hi,
just getting ready to buy the 32/36 weber and all of a sudden I goot hit with this question: Linkage rotation...clockwise or counterclockwise.
can you guys help me with this or direct me to the people you purchsed your carburator (allready set for the correct intake and air jets) from
Thanks

yea, as if one is holding the carb in one's hands and looking at the linkage and shaft assy. It would be CCW, or counter clockwise, or anti-clockwise
