hey everyone, feels like im posting problems here all too often haha.

im not sure whether this is just me being finicky or its normal, basically when my car is cold it happens alot worse but still happens abit when its up to temperature.

basically when i put my foot down, it takes about 3 seconds when cold and about a second when its hot to actually feel the change, i was thinking this was my mixture but i have had a carb rebuild and set up the mixture so is this just normal?? its a 1.7

Cheers

I don't think there is anything unusual with that specially when you have a manual choke. I had the same thing going on with my B200 on a 360. There are a lot of changes in the engine's temperature the first seconds after you start the car so the engine just has to warm a little bit up before it can run normally.

yeh i guess im jst used to injection, not to worry i was just seein if there was any ways to make the throttle response any better.

Cheers

Perhaps you need to adjust choke? I know my car has serious trouble running cold and one reason is that choke adjustment is way off, second reason is that carb base is badly warped, but I'm afraid to straighten it as last time I did that I lost idle and with that carb I could never get it back even everything is in specs and clean, so this 2nd one stays warped, at least it runs with it

the carb has just been rebuilt and the base has been skimmed, i have set up the choke by what it says in the haynes for the car and it seems to work right, there are no air leaks or anything it idles nice and low with no roughness atall

is there a guide for setting up the choke?

Thanks alot

if any thing a carb car should be more responsive than a standard inj one.

thats what power boost valves claim to achieve, a responce like a carb car..

i have to say mine was always instant responce wise. and if i remember right, the mixture could change it and make a bit of a delay so could be that.

cheers, would you happen to know if it means its abit rich or too lean if its bogging down?? it used to be alright but since i had the carb rebuilt its gone slightly off. it was me who set up the choke and the mixture so i may not have got it spot on.

cheers

at a guess, it could be too rich turn it down a 1/4 at a time and test after every tweak. if that doesent work try to rich it up a bit.


Cheers
will

yeah i guess trial and error is probably best since i dont have a co2 meter. i may just pop to an mot centre and ask if they can test it whilst i adjust. probably best way to go

Make sure the acceleration jet is squirting fuelout when you open the throttle.

how would i check this? im sure i have seen it in another thread but cant find the info.

cheers

Just squeeze the throttle linkage with your hand (leave the engine off), you should see a squirt of fuel going down one of the barrels.

cheers chris ill go check that now

right ive just been and checked it, it does squirt fuel out but it doesnt spray it to the bottom of the carb it sprays it against the side of the barrel and it only comes out on about 60% throttle.

is that right or could it have a slight blockage??
