DGV 32/36 series weber jetting

[gldgti]

hey guys,

I have a new weber 32/36 coming to go on the 1600 and i'm hunting for basic jetting settings. if anyone is running this carbie and you can get better than 8.5l/100km, i'd love to know your jet settings.

cheers,

aydan

blow the fuel, drill them out
more fuel more power
thats the way i like it

[gldgti]

hmm... anyone else?

btw man, having bigger jets isnt the way to get more power... theres a thing called mixture - if its not right, you could be using lots of fuel and have no power aswell....

That's very correct.

Is this the same carby that was made by Holley/Solex and a few other companies?

I had the Holley version on a previous Golf and had the jet sizes written down somewhere. I used an insulator plate from a Toyota Crown to space it up about 6mm for some reason onthe Passat TS manifold. When I bought the car originally it had an adapter which could never work.

My only advice ATM (as I'm going through the same process too but on a 1.8L) is to put it on as is, set the idle speed & mixture & go from there & see what your fuel economy is & by feel eg. stumbles, choking, lean backfire's etc.

You could put it on a dyno to get you in the ball park with both the cruise & full power. Driving on the street is a different load to a dyno, that's why I said ball park.

I had to do this with my new 750 Vac on my ute from scratch & it does take time but I got it spot on. On the dyno I made some adjustment's to the jetting & power valve & made more clean power, but on the street it would bog & choke. Two totally different setting's for dyno & street.

Another trick is use a oxy sensor & a multimeter to measure lambda. This is also useful too.

Or borrow a A/F meter.

Just remember that some people do mod the carb. air bleed's, choke's & what not which can leed you up the garden path & chasing your tail.
That's why I had mine professonally rebuilt (it cost's a bit but I know exactly what I'm dealing with to start off) back to a early stock mk2 escort weber without the pollution crap.

Hey Phill, what size holley did you fit & how'd it perform? eg. 350 twin barrel?

I seen a couple of pics of heavily modded 8v's using 4 barrel's & it worked fine. Also seen a draw through turbo 16V witha 4 barrel holley & it also made good power.

carbie came today!

its in good condition, still has some fuel dampness on the alloy and obviously nice and clean. should be on by the end of the week.

i will put it on as is, see if it works etc. should be ok for starters.

i love the idea of the progressive, i get pretty decent highway economy atm, so if i can keep that i'll be cheering.

meanwhile my ignition is causing all kinds of trouble, since i put in .7mm gap plugs i had weak spark, wouldnt idle or go properly below 2000rpm. doing all kinds of crazy things. also, temp gauge has gone wildly high a couple of times - but i dont know if its actually getting hot, or if current from the plugs is leaking out and modifying the temp senders voltage....

meanwhile, the battery was flattened while highway driving 200km, because of the dodgy ignition stuff! arrgh!

swapped the old .6mm plugs in, and things have settled back down.

if i want to put another coil in it, like a new one, or slightly hihger powered just to make sure its reliable, what should i get and how do i implement it? (this is the novice petrol owner coming in.... gimme a diesel !)

[ontarv]

in all seriousness i still get good economy
if your keeping your revs below 4g's or so
your sec's don't open so you get good economy
with a worked eng and jetted out i prob get 8 to 9ks per L
around town driving normal but running hard it likes the petrol
i run a gt40r coil new type not the cylinder shape one
it has a bit more punch

A lot of those issues can be caused by bad earths. I'd start by cleaning up or replacing the battery earth lead paying particular attention to where it is bolted to the bodywork as well as the gearbox. It would also be a good idea to check the earth on the ignition coil itself and the earth strap on the alternator. There's also a couple of brass earth terminals on the chassis rails below the headlights just cleaning those up made my headlights a lot brighter. (But not as bright as the relays, new lenses and 130/100w globes did! )


Happy hunting

8 or 9 k's per litre?

thats bad...

anyway...

the carb is on! looks great too, and boy what a sucking noise, you can hear all your throttle position changes through the firewall!

anyway, the carb seems to be jetted rather badly for the 1600, feels not much better than the standard carb which says to me its way too rich. who knows whats in there...

i've been searching around for jettings, so far im thinking i might go with a common setup for the MGB: 55/50 idle, 140/135 mains and 170/160 air correctors.

at least it should provide a reasonable stating point.

thoughts?

also, i DID have abad earth. thanks pete! also, i had a leaky dizzy, was telling me the car was running hot! haha
