Yeah , I would have thought. A lean mix is harder to ignite , hence these kick arse ignition systems on modern cars, so that would make it an unlikely culprit (I think someone said retarded when they meant advanced πŸ™‚) .
Mine jingles away at 8deg ,not to bad at 4 using 96oct. On 100+ set a 8 deg its a different car ......it loves it .
I goofed and accidently bought low comp pistons which didnt become evident untill I fitted them....so I whacked 70thou off the deck and bought a power pulley. Turns out I probly shoulda only taken 60 thou of it (like the guy at the machine shop said πŸ™„). So Im guessing comp ratio is about 9.75-10:1 .
Is it slow as hell at 4 degrees? I get the feeling from the brief drive I had a few days ago when I took the previous picture that it was a lot better on the manual fuel pump (i had my suspicions the electronic one was overfueling it) although I havent tested this properly.
My local mechanic looked at it briefly a few weeks back and said it was running a bit lean if anything (I was worried it was running rich). Would advancing the timing from 8BTDC to 6 or 4 cure this? I'm guessing different spark plugs or coil could help too? I've got an electronic pinto bosch setup now.
Its got a weber 32/36 on it and I tried to adjust the idle screw to no avail. Someone has screwed this right in at one point so i'm hoping they didnt damage it. Its backed out around 2 1/2 turns as people suggest. I tried to use a colour tune on it but didnt have much luck there.

I think by that you mean the mixture screw. Are you sure you're turning the right one? Certainly it should have an affect if, for example, you slowly turn it in then there will be a point where the engine will stutter/stumble and, if you keep screwing it in, the engine will stop. If this isn't happening then either something is wrong, or you are turning the wrong screw.

Take it out completely (count/memorise the turns/position so you can put it back the same), it should look similar to the below, the point isn't broken off is it?

Going from 8` Before Top Dead Centre to 4` BTDC means the spark is happening later so you`re retarding the ignition, not advancing. Retarding will slow the idle - but that`s not the issue, you set the timing right first then adjust the idle speed .
As Paul says, if you keep screwing the mixture screw in it will weaken the mixture until eventually it will stall. There`s something wrong if it`s having no effect.

Apologies I do mean mixture screw not idle screw. I did rebuild this carb but I'm thinking I could do with a new one every day, I wish I'd done this when I got the car. The last time I tried to get the mixture screw out I couldnt, I could only get it to turn to the edge but im sure I had it out when i rebuilt it. The screw is different to the picture posted above its deeper in the casting. I wish I could find a picture of it but it basically needs a screwdriver in the casting to turn it out and it doesnt have the spring/finger adjustment you see more often. I know this carb is off a 2.0 Granada from the serial number (possibly the engine its self too as its not from my Capri) . Maybe theres something stuck in it/its damaged... it never has any affect from memory. i played around with it a lot a few months back and when I had a garage look at this, they timed it to +10 and screwed that all the way in!!

Well you definitely need to sort that mixture screw out, it sounds like you may even have the wrong one in there, take it out and have a check. It's normal to use a screwdriver to adjust it. It appears to be not metering at all which means your car will run excessively rich.

Yeah I think I should get a new carb when I can for this thing and start from there. The garage said it was running lean if anything when they gas tested it. Not the same people who screwed the mixture screw in and timed it to 10 BTDC

There's nothing wrong with 10 degrees if it runs ok with no pinking. I have mine at 8 degrees which is the book setting and I find it runs well at that.

Your carb may only need a couple of tweaks/parts, I don't think I'd go to the expense of a complete new one.

Some 32 36 carbs have an idle bypass screw , something to do with tamper proof idle mix ,if it is one of them carbs the idle mix screw is recessed as you describe and has limited adjustment. I wound up using a vacuum gauge to set idle mix .
You should try to find info for the granada engine coz the jets and correctors are probly different too. Possibly confirm the ID of the carb might help.
The leckie fuel pump may well have overridden the float valve ( did carb have black plastic float or brass ?) as they can provide nearly twice the fuel pressure as a mechanical one. If fuel is sneaking in causing a high float level it will make fiddling with the idle mix screw ( if that what you have )almost pointless .

I'd agree with Paul - a brand new carb is going to be Β£200-300 whereas the cost of a carb rebuild kit is something like Β£25 and a few tweaks afterwards

Cheers for the advice guys. I did rebuild this last year with the Β£25 weber gasket kit/needle etc plus a new power valve . It ran ok but at this point and I followed some youtube vids/haynes to take things off, clean, put new stuff on. I didnt realise the accelerator pump was the wrong way around before so when I put the new one back on it seemed to make sense that way round :oops: anyway fast forward a few months and its all working well just this noise . I'm sure I had the mixture valve out at this point , cleaned it and put it back in. Now I cant get it out it seems. I wish I was with the car but I dont have a picture of the valve. I'm going to fit new base plate gaskets again as I renewed the top gasket recently due to it being a bit damp.
Its brass floats in this one by the way and I did set it how the manual said.

From looking up the Carb tab it was from an 83 Granada and I cant get much info from the block serial as its different from my cars vin so i'm guessing both units are from a Granada at this point. Reason for thinking of getting another 32/36 is this has been a pain in the arse while i've learned about this car for 3 years and something I think I should just start fresh.

Heres some old pics of the block and carb serials I found. I'll take a photo of the mixture screw once i'm back home.

Ive been in the same situation in the past, whatever I did to the Weber I had just didnt seem to make any difference so i bit the bullet and bought a used, known to be good, replacement. It made all the difference in the world.

I was never certain what was actually wrong with the old one, some said it might be down to a damaged seat for the mixture screw, others that it was an accumulation of wear and tear on the spindle or an internal blockage.

Hey so I'm back home now and thought i'd ad a picture of the mixture screw and the number in the casting to this Carb. I stated to think while I was away, maybe I could find a second hand lower half to the carb or stripped out carb and use all the parts off this so I have a new mixture screw/hopefully not damage base (assuming it is).

Hopefully someone will confirm if that is indeed a version of this carb where the mixture screw is recessed as Hamish (Mc Tool) describes, certainly looks like it and I have seen this before actually in one of the manuals. Perhaps best thing to do first would be to remove your mixture screw (I know you said it doesn't appear to want to come out but it surely must do?) and compare to the one in that link you posted.

It`s a completely different casting to `normal`. Looks as though it was a`tamperproofed` later version, i.e. set at factory and sealed with a plug? (Assuming it`s the same orientation as the vac pipe is there) Aa Paul says , it must come out, but whereas we have the knurled end to pull it, if there`s any stickiness you`ve got nothing to get hold of. Tiny drop of superglue on the end of your screwdriver?

I was thinking of tape, sticky side out, on the end of the screwdriver.

Hey everyone! Im back... sorry about the delay on this. I finally found time to have a go at adjusting the clutch Pedal and of course filmed it all.

Its a lot better but i'm wondering If I should have adjusted it out even more. the bite is around 3/4 of the way up the pedal (maybe a bit lower) and is making it a lot easier to drive. I didnt want to go too far at first as the cable looks like it could slip out of the clutch fork if its got too much slack on it.
From what i'm getting from the Haynes you should get an a assistant to help, didnt have that luxury so just went for it but it says 4mm of travel at the pedal which it seems I have now... did I do well? :lol:

It can do one wheel peels now but annoyingly the weird noise is still hanging around once warmed up and i'm getting a clunk going into 3rd sometimes.

Anyway, enjoy.....
