Good carb. Just get all the sizes of jets. And jet it correctly for your motor and altitude. It's not always needed, but i always put a fuel pump on with them. You'll see roughly a 7hp gain with the weber. It's nice because the first barrel is about the same size as stock model a carb, so you won't see a decrease in gas Milage, but when you get into the second barrel you really see the difference. I recomend the weber and the strombergs for people who want more carboration from their A. The strombergs are more for people who want the power all the time, and don't care as much about gas Milage.
 
Yo' Bill Lee,
On Minerva, the addition of a Weber & a single point Mallory dist. made her like a DIFFERENT car!! Much better mileage with that setup! I had to go up 1 size on the primary intermediate jet. It changes easily from the outside, R/H SIDE OF THE CARB.
Mine ran generally lean, until I added an electric fuel pump, then it was still ever so SLIGHTLY LEAN, until I put the K&N air filter on, then it was PERFECT! With the accelerator pump, I didn't even need the choke, that I meticiouslly (sp?) disguised to look "STOCK"!
I will leave Vermin stock & see how he performs with a Zenith or a Tillotson.
Bill W. (Bill, piercemanifolds.com can help you with any jets you might need. They set me up with a kit of 1 size larger on all the fuel jets & one size smaller, on all the air bleeds. He based that on the sizes of the original jets, that came on my instruction sheet. Cost Me &65.00.
I think that SOME Weber's come jetted for a VW-Rabbit! I read that some suppliers re-jet them? I "think" Arizona Model A place does that??
Maybe some suppliers might "CHIME-IN"??
If you're using a Weber from an old Pinto, I read that the factory used a stop, to prevent the secondary from opening during break in, & sometimes it was NOT removed at the first dealer service!!

As logan said , great , Arizona Model A , Sammy should be back from National meet ,Ask for the KIWI discount ,
 
I had my first progressive Webber on my Volkswagen back in the '80's. There was no doubt that I was going to put one on my AA.
 
Reds headers. $170 you'll get a set of tube headers, go to the auto parts store and pick up a can of header exhaust paint & primer. Scuff and paint them so they don't rust. That's your cheapest option for a performance header. And honestly, I don't see any benefit from spending the extra $2-300 on other performance headers.
 
will run great with stock exhaust header, did not see much improvement with the tube header, did run better with an aries ss muffler,
 
I run mine with the stock exhaust manifold and an Aries SS performance exhaust system. With a heavely modified engine I had to richen up the idle and primary main jet about 10 steps. It was still pulling strong at 2800 rpm when I chickened out and let off. Thought about going to a 38/38 synchronus carb but not sure I need it.
 
I have the Weber on my 29 Tudor. That combined with the high compression head, electronic ignition and overdrive make the car a lot more capable of highway speeds and gives you a little extra boost if you need it. I will say that personally I don't really like the look of the Weber but the performance is the selling point. I also run an electric fuel pump with a 5 psi regulator to the carb.

If you are considering the weber I would highly suggest that after you install it you go back and make the proper adjustments for fuel and air mixture and idle. Once you do that you will notice the difference not only on the road but at the pump as well.

It is pricey but in my opinion worth it if you plan on your car being a touring driver. Good luck.

Your pump may not be pumping 5psi, but 5psi is way to much for a weber. 2-2.5 is the normal pressure that the weber runs best at. Your pump probably isn't putting out 5psi, because if it was your weber wouldn't run worth a crap.
