hey guys my car has been playing up its the sierra with 1.6 vt conversion carby my points were constantly getting dirty at di and dizy was playing up. so i changed my dizzy and cap over with old one and now the problems the same? it will turn on if you give it gas and will stall soon as you back off or without gas it will turn over and then die straight away. is there any ideas of what it could be soon as its running it runs fine. any help at all would be great as i need to get it fixed or to a mechanic before i loose my lisence on december 2nd.
thanks guys

You run a points dizzy Sounds like you have a fuel blockage somewhere in the carb. When was it cleaned and overhauled?

points on the cap but electric dizzy and on the carby would not know as i havnt touched the carby since i brought it when i swapped the engine after 1st one died i just swapped intake manifolds over instead of trying to remeber how the vacume lines all run

Simple fix. Go to a carby specialist. You'll not have another poor idle drama for a long long time after that.

Zook carbys have really small internal passages and idle jets. It doesnt take much crap to block them up. Either clean it yourself if you have the skills or get someone to clean/rebuild it for you. Run a second fuel filter between your fuel pump and the carby inlet too.

Oh, and zooks dont have points

Hi lukes_89,

It doesnt sound like an electrical/ignition problem to me, definitely a carby problem, sounds like the primary/idle jet is blocked if it only runs when you give it gas...

I agree with Reubs, take it to a carby specialist !

what he says.

however it is fucking petrol not gas

and no i don't want fucking fries but i will have some chips.

[lukes_89]

sorry shep i guess ill speak to the old man he knows a little about carbys other wise i better start saving so i can get it fixed i hate being a poor uni student

[shep]

try this.
swap #2 and #3 plug leads around and start the motor, make it backfire heaps. swap the leads back and check that all the vacuum lines are connected
properly.

if that gets a good idle then you will need to clean the idle and fuel cutout bits of the carby.
you should also hear a click from the carby when ya turn the ignition to run if not
then the fuel cutout solenoid is stuffed.

also replace the fuel filter near the tank with the correct filter( it has a bit of a water trap thing built in)
and put a filter between the fuel pump and the carby. i will say it again as it is important.
put a filter between the fuel pump and the carby.
i stuffed around for ages with a non idling car and the only way to fix it properly is to
clean out the carby and fit new filters.

and remember it is petrol not gas, gas is for taxi's

[lukes_89]

i tried all methods you said shep and i have a answer its got to do with carby being blocked or needing work as i tried the spark plugs didnt idle it would start today idle for about 30seconds then die. i also have some amazing engine and carbie cleaner i got from a mate whos a boat mechanic called power tune from quicksilver its a carby and engine cleaner i used it when i gave my car a mouth full of water a while back and since i used it its been idling rough but idling as my timing is out but its been idling for half an hour. so its a short term fix. thanks guys for all your help

check your idle solenoid on the side of the carbi has power. This happened to mine recently as this lost all power so the car wouldn't idle. i could start it but as soon as i took my foot off the car would die.

chadd1981, same problem, but intermittent. Idles good 90% of the time. but when changing down to stop (particularly), you can see the tacho dropping to zero and then won't idle at all when you have to stop.
(Revving fuck out of the Zook at the lights to keep it going....
........not a real good look..........won't fuck'n idle, will it)
Going again, up through the gears, it'll clear and idle perfect at all stops..
.. till the next..yep.
Worked this out but, before restarting, push the accelerator to the floor and let it off fully, and then restart it, it'll idle perfect (no more trying to keep it going at the lights, just do that)

This sound like yours?

No mine was totally different as mine would not idle full stop, even after revving the engine. As soon as the revs dropped the engine died. Started straight up and as long i had my foot on the accelerator a little keeping the revs above 1500. i tested the power to the soleniod and there was nothing so traced it back and discovered that the relay was diead, changed that and all my problems were fixed.

Had that problem... would only really happen after coming off the highway after about half an hour or more. Carby rebuild & tune = problem fixed.

yes mine would not idle at all unless was around 1500 or foot on accelerator the whole time would just stop but now all of a sudden my zook idles perfect now i dont know what happened took it in the mud now it runs :S but i lost my liscence as of midnight so 6 months to go and counting but in this time im planning on doing some mods to her
