engine and drivetrain To hog or not to hog? Advice needed.

[Guest Anonymous]

Looking for "flow" advice. I am running a Weber 32/36 with a stock engine and stock 2 hole manifold (Stahl header, Crane XR3000, Aiwa stereo). The Weber is sitting on a spacer (3/8" tall or so) that is one big opening. I am under the belief that unobstructed flow = better performance and the "divider" between the two holes looks like an obstruction when viewed with the spacer. In an effort to eek out every inch of horsepower, should I:

1) Remove the spacer and bolt directly to the manifold?

2) Hog out the manifold to match the spacer opening?

3) Leave everything as it is?

Option #4 will be the 38/38....but I have to save my pennies first.

Thanks in advance...

(might look familiar)

...my WEBER perscription:

32/36

Float Level 40mm

PRIMARY

idle 60

main 140

air correction 145

SECONDARY

idle 55

main 170

air correction 175

....keep in mind that depending on how high you are (above sea level)and ambient temps, extreme cold or hot either way, these settings may need a half to full jet size up or down on Main & Air Correction.ALWAYS keep the AIR Correction jet size larger than it's mated Main jet (170 main - 175,180,190 air Corr.)

Adjust throttle control shaft (carb to firewall shaft)so it is level and straight - inline with carb, adjust with piviot bracket on firewall. Then adjust rod end (on rod coming up from pedal box to control shaft)to achieve full throttle opening on carb stop when depressing gas pedal and you looking at rear of carb to confirm full opening.

DO NOT PRESUME 'a stock rebuild" ????

this carb is so simple, but even simpler for someone to s_ _ _ up !!!

BUY & READ any of the books about WEBER carbs

>>>>>>>>>>>>>----------<<<<<<<<<<------<<<<<>>>>>>>>>------

The other major improvement is when you have the carb top section off, plug the hole in the carb that mates with a tiny brass jet in the carb top. There's only one.

Use epoxy to plug the brass tube.

It's a secondary enrichment passage, allows "course" amount of gas to be drawn on secondary opening. By closing it off you run solely on main and air correction jets. Much more precise than with passage open. Trust me, you'll grin after you feel improvement !!

Go to Pierce Manifold link below , order "complete " carb overhaul kit, some extra top section gaskets, and order a How To Weber Book from them. You'll be an expert in no time.

Don't tell anybody.....but yes, I am driving the Cherokee at this point. When the 2002 is put back together (Wednesday probably) I'm driving that until the cold weather...then I'll pry the 325i away from my wife.

Here is where I open myself up for flames:

Jeep Cherokee

-25 miles per gallon with plenty of torque

-Awesome off road capabilities (and yes, I use them)

-4000 lb towing capacity (plenty for the pop-up or utility trailers that I haul)

-Alpine stereo system with 12 disc CD changer, and exhaust that is so quiet I can hear the stereo.

-Power window/locks and a heater that works

-Incredibly reliable, 4 years and only routine maintenance plus one radiator.

-Sucks in corners

I high-centered on a snow bank in the road, was able to back off and make it to work during a blizzard.

I don't care what people say about "SUV"s, the Cherokee is a perfect compliment to the 2002 and 325i.

if you want to bolt it on and see if you feel a

difference. gimme a call. you could also drive

mine with the 38 and see if you just want to

splurge for the bigger weber - if you're going to hog

it go big!

Stock Solex was something like a 32/32, which is why the manifold opening is smaller than your Weber. As of now, you have not exploited your carb to its full potential. As the 32mm opening restricts your 36mm throat.

I just use public transportation in NYC during the winter. Reno and Cashmere (91 325i) hibernate when there's snow on the ground. On the rare occasion I have to travel far with the white stuff on the ground, rental or fly baby!
