hi all, picked up my indy a week ago now, just wondering if you guys can tell me anything about the engine, obviously pinto but im not sure what carbs they are? they are twin webbers but never seen 'em before

also there is a pic of the underside of the bonnet where the carbs are situated, does this look ok? also the is no choke or air filter, any problems with this, at the moment im putting my hand over the carbs to act as a choke when starting from cold, sorry about any silly questions, pretty new to ford bits

looks like a weber dgas carb. don't know which one though. 36 maybe? i think they were a common conversion for 2.0 pintos. the 36dgas was from a 3 litre capri if i remember right

ooh, and technically not what you'd call 'twin webers' but it is 'A' twin choke weber

yep its a dgas as its got the sector gears, not a bad carb if setup correctly but bike carbs are better in my opinion, maybe a winter upgrade coming along!!!

Cheers

The carb is referred to as a single Weber Twinchoke Downdraught...

As above a good carb unless the engine internals are seriously upgraded.

The PO has ground off the top of the carb and removed the choke flaps and linkage. This is obviously so that it fits under the bonnet. I would examine how much air gap you've got between the filter and the bonnet and that it's not getting sucked down limiting performance.

You're not running a filter which will allow dust and grit to enter the engine and damage it eventually.

Dual Twinchoke 40 Webers look like this:

I'd get a nice foam filter for it, save knackering your valves etc with dirt and bugs - cut the bonnet so the engine can draw in nice cool air via a pipercross or similar.

maybe even get a scoop if your into boy racer type stuff?

As above. It looks like bonnet clearance was an issue so the carb was ground down (and not very evenly either- OCD ). If there isn't a chokes width from the end of the carb to the bonnet you'll be losing power and running without a filter is a seriously bad idea.

The grit and dust that gets sucked into the engine will act as a lovely grinding paste when mixed with some petrol and oil and ruin the engine in no time.

Personally I'd look at a conversion to bike carbs and some proper filters.....

ok cool, so what sort of price am i looking at to get a bike carb set up? i would preffer to go striaght into that rather than cut holes in the bonnet that i wiould not need eventualy?

not to bothered about second hand though, maybe this is a good route, and as a noob to carbs what are they like to set up??

bike carb set up will cost you in the region of £400 if you have a nice stainless manifold made by bogg bros (£200), £50-£100 for carbs themselves and £100 for extra's like Pipercross backplate and filter etc

Pumping the accelerator pedal 2 or 3 times should be enough to start it without messing about with covering the chokes. Give it a whirl.

Are you planning to make your inlet manifold? Any bike carbs over 600cc will do, best to get ones with a tps sensor already on, mine are from a Honda cb600 hornet and jets drilled out to 1.55 are perfect.

You then have a choice of either making the manifold fit the carb inlets and also fitting the block or re-spacing the carbs so that the manifold and carb spacing is the same.

I have a few pictures in my gallery of my manifold, if you choose the easier option in my view of making the manifold suit both so no carb re-spacing is necessary then because of the extra length of the tubes a bonnet hole maybe needed.

I made mine for about £40 inc the carbs, although ebayers have twigged that carbs are now sought after and the prices gone up but if you're in no rush then there are still bargains to be had.

theres some photos of mine here in various guises/states

That black stuff on the bottom of the bonnet is fuel being spit back by the carb, probably during warm up, as above you need an air cleaner of some type.
In the mean time you may get away with cutting down a K & N Filter or paper type and have the bonnet hold it in place.

probably need to cut the bonnet if you fit bike carbs as there isnt enough space under the bonnet for the filter It also allows cold air to the intake
