How do you identify a Weber carb? Apart from the Weber logo stamp....

Post by **eben** » Sun Oct 15, 2006 2:24 pm

if you are talking about what model.... it is normally stamped on the body

no force at all......

Its normally stamped on the base somewhere.

I got the wrong mix in my helmit today what is the difference between Twin & Progressive?

you have a lot to learn my little padawan learner.

"twin" - IDF or IDA or similar, like the famous sidedraughts.... one carb, two throats, so with two IDFs, you have 4 throats, one for each cylinder.

Progressive. Usually one carb with two throats (may be same sizes or different). The first throat usually operates to about 75% of its throttle position before the second one starts to open, they both hit 100% open at the same time.

Mmmmm...... Me thinks it's the twin.... I'll take some pick and post them as I'm a bit short on time now..... oh and it running on a single port motor.....

It's likely a Ford OE carb Weber 38 DGAS for a V6 run fixed chokes like 26 & 28 with monster main jets. The single port probably runs like crap and drinks like a fish. These carbs are not recommended for a 1600 motor, they just can't be set up properly. A mate of mine spent a few hundred Rand on getting one to run on his 1641 and got rid of it in the end, a Weber 36 DCD is the better carb as it's 100% more tunable and easy to set up.
I have a lot of info regarding jetting etc for the 36 if you need, and jets are still relatively cheap.

Well I eventualy got spec's
69mm stroke
94mm pistons
All ballanced
38 Weber progressive 2bb carb from the Ford V6
Cam same profile as the Ford V6 (he did not have the cam profile on hand) but it is wild

Got the call on Friday that I could fetch the Force and I was there as fast as a Tie Fighter on a rebel x-wing...

Fitted the Force and set the acceleration cable wrong so when I started it, it reved like a two stroke and made all the kiddies in the road

Decided to keep the mags for The DarkSide...

But I need to tweak the timing abit as it pings and doesn't perform 100%

Keep the Hocky Rs, rare and always looked good on a bug. If it wasnt for the PCD, I may be tempted to buy those mags myself.....

Am I right when I look at the pictures??? Great big carb, teeny little single port manifold.

Cam profile same as the ford V6??? Who cares, its not a ford V6!!!! I am so going to come around to your place and ruin your day when we check that engine out!!!
Why would he install 94s when they are not common and 92 are available from all areas of CPT??? Then have the genius idea of putting that carb on that manifold!!! Where is this guy situated??? Ottery?? Near the BP garage? The guy who swears that a single port is stronger than a twin port head and can make more power if worked correctly???
