hi ive just found and fittted an new lickage found in the uk that once fitted with an new fuel pump jet on webber 32 36 cab . open both butterfly at one . in which greatly improves top end an take off preformance for pinto motor

Those twin choke webers may have gone well if you could synchronise the chokes at high engine speeds, but off the lights. ? don't really think so. I reckon it's best to leave alone and let the small choke come in first. Maybe if you put in a hot cam but not otherwise. I well remember guys with 1300 Escorts trying this out by bolting a 3 litre Granada carby on their engine somehow, thinking all that extra fuel is gonna win them the traffic lights grand prix . all that happened was a loud bluuuggghh noise as the engine flooded and died.
Maybe leave it as Ford intended, after all the 2 litre pinto wasn't a bad motor in standard form, and has pretty well stood the test of time

The twin 36mm webber already has this feature but you NEED to know how to jet correctly for THAT engine & tune them to get the best out of them

I don't see how it's going to improve top end performance?

Cars need more air to get them to go better , not more fuel . Better air fuel is what you seek . Dumping more petrol into an engine will not make it perform any better at all .
So it sounds like you have a new linkage that opens both butterflys at the same time, and you have a new bigger accelerator pump, correct ? it will probably require a few more revs to get it off the mark.

hi yes new new an bigger accelerator pump in the kit

Cant see a change in top end performance, because both butterflys will be wide open in both circumstanses, mid range will be better fuel consumption will shoot up.

I couldn't agree more.

Ditto.
The 32mm was there for economy with a progressive link to the 36mm for power

hi the guy said would be quicker of the mark . also with an webber air cleaner more air an more fuel

Weber is spelt with only one b, (as in Weber carbies) just saying.

hi ok thanks

A common single linkage will make stuff all difference on a stock 28/36 carb because the moment you slam the throttle hard down BOTH chokes are still going to be wide open.
What other engine & vehicle mods have been done to justify a few milliseconds of throttle response at launch.
Presuming it's an otherwise stock car/engine . > You could probably get the same quicker response by not having a passenger & or taking the spare wheel & other extra crap out of the boot.

Aftermarket air filters make stuff all difference on a stock engine except make more induction noise, (carb sucking air noise).
All those sorts of mods will only really be noticable if theres a whole lot of small mods done at the same time AND done correctly.

very true that would you better fitting an weber 38 , over an 32 36 cab

The best and cheapest "get off the line" improvement for the old school Pommy Fords used to be to change the diff head. Escort 1100's and 1300 vans had 4.44 and 4.1 diffs.
These put in behind engines fast cams and tuned carbs made for great acceleration. But it is at the cost of top end speed and increases fuel consumption.
To get the best of both worlds you need to consider changing to a 5 speed gearbox too.
The standard 4 speed usually has a 1:1 fourth, most 5 speeds of the day had 1:1 fourth and overdrive ratio on 5th. Coupled to a 4.1 diff you get fast acceleration and sensible rpm for open road driving.
Yes, but its really best to do it in conjunction with a cam change, porting etc. Doing some of these mods in isolation can cause more problems than they solve. What mark Cortina we talking here?

Simplest is this.
Get the carb cleaned & fully rekitted professionally Fit a "ram flow" air filter pod to the carb Bolt on a set of TUNED extractors with a 2" exhaust system (DON'T go bigger without extensive engine mods, it's just not worth it) Find & fit a modern thermal controlled fan blade, (thermal controlled free wheeling fan hub) (can't remember the modern name) NOT an electric fan!
Those simple mods along with make a big difference & fairly cheaply
Next best mod is a Sierra 5 speed on the std diff ratio

thanks guys its an mark 5 Cortina I see what u mean if I put an weber 38 and rest is standard just waste an money too. with out doing the little mods too

Next Weber model up is a twin 36mm with single linkage. You WILL have to get it re-jetted to suit that specific engine. If you don't, it will probably be a pig to tune, (they can already be a pig at times)

thanks so true , that was also going fit four pot webers on the pinto motor but what ive heard there an pig to balance up ,. so in end ive got with fitting an new 32/36 weber with ramflow air fitter too an god tune up ,,

Fit a set of "tuned extractors" as well, even on the stock exhaust they are worth it.
vhpacer1971,

hi just fitted the weber , now the old fuel pump gone is there any tricks in fitting an new one , I remember years ago cortina on fire due to fuel lines was that true

Yes the ose that went from pum to the carb. Happened to me.
