Anyone had a car with a manual choke, I recently passed my test and got my mums old car for running around in but struggling with the choke. Anyone got any hints???

Yep, the choke enriches the fuel mixture when the engine is cold.

So, when cold (like first thing in morning), pull out (fully) start car and drive off. Over the first mile or so gradually push it back in, you want it "off" as soon as possible as it use a lot more fuel.

As a guide, an engine should idle at about 850 rpm (you may or may not have a rev counter, doen't really matter). As the engine warms up, the choke will cause it to idle faster.

One of my old cars, a fiesta, would idle when stone cold, choke fully out at about 900 rpm. AIf you left it running, as it warmed the idle would increase. Fully hot and choke out would be about 1500-1800 rpm, clearly to high.

So, once you get "used" to how fast the car idles when fully hot, if your on choke and say stop at lights, if it's idling faster then this, push the choke in a bit.

You will find that if you get moving and have no need to stop, you could probably just push the choke in, really only needed when idling and pulling away.

Hope this helps,

Martin

Forgot to add, once the cars warmed up, you may find that don't need the choke again all day, depends on the car. Mine only needed it first thing in the morning, unless it was very cold.

What type of car is it?

I had a Vauxhall Nova a couple of years ago! It took me a few months to get used to the Manual Choke.

Pull it out, start the engine. Push it in a bit till it struggles, pull it out until it stops. Warm it a bit, push it in further till it struggles, pull it out till it stops. Repeat till all the way in

The best way to use the manual choke is to pull it out full in the mornings. Start the car then ease it in just a bit to make sure it doen't stall. I think you may be pushing the choke in to fast before it warms. As it warms more you can continute to ease the choke in a bit more and finally after several minutes of driving the choke should be all the way in.

i learnt to drive on a car with a manual choke. it's pretty straight forward: pull it out when you start the car from cold (and this may include if it's been left standing for a couple of hours or more) and push it in when the temperature gauge shows the engine is warming up - if it starts to run a bit roughly then you've pushed it in too soon so you pull it out part of the way again.

if you're used to an automatic choke make sure you remember to push it in - if you don't the engine runs too fast and uses too much petrol.

I have a lot of problems trying to start my mini in the mornings. Even with the choke out its still quite a struggle. I find that I always have the pull the choke out to get it to start no matter what.
