5k randomly losing power, can't drive

[scope]

hi

this is only happened twice but still worth asking. what happens is that nothing happens. if i try to rev it just makes a loud sucking sound from the carb and the revs lower almost to die, then if i stop accelerating it comes back and idles for a few seconds then dies by itself (this is all with the choke out cause car won't idle in the cold weather )

it never does it straight from starting only when i'm driving along and then it just does it

both times it's been wet (water getting somewhere it shouldn't ??) i don't have an air cleaner on my carb so maybe something is getting in ?

thanks for any help

Mega cold weather only? If so, perhaps your carb might be freezing. My old Pulsar was a nightmare for doing that.

One of my old 4k's did exactly the same thing afew times, only after you had been driving for a bit and it would die, it was the carby.

i normally let the car warm up for a few mins before i leave but can that still happen?

dodgy carb?
sounds like its struggling for fuel at times

it has fuel definitly and it's only happened twice on cold mornings.. if it happened more often i'd maybe think the carb. a guy at work said maybe there is water getting in the fuel lines? or even just water in the tank

i tried to drive it home before after work but did the same thing (last time it just fixed itself)

I don't know if it's a problem Starlets get. But, it isn't a "warm the car up" issue, it usually actually happens when you're driving along at motorway speeds on really cold nights. That was what happened to the little carbie FWD Sunny's anyway.

I'd be looking at the dodgy carb theory, if that's what has happened on Starlets, rather than my frozen carb theory since nobody has reported that as a Starlet problem.

fuel maybe fine upto the carb.... but whats happening after then?

its always hard to diagnose over the net, but what you describe is like its running out of fuel.

Its the carb icing up,if you still have the original air cleaner housing,there is a cold weather adjuster on the housing,slide that across to suck in warm air off the exhaust manifold(as long as the hot air tube is still connected).Petrol sticks to the sides of the carb when the carb has iced up.I had this problem many years ago and took a wee while to figure out what was happening.(the hot air tube was missing!!!!)If you have a factory owners manual,its on page 51 ,1976 Corolla owners manual)

exactly what happened on the KE70 i had. once the hot-air intake was fitted , problem gone.

ahh i don't have the original housing ay. have been trying to find one though. cheers for that, will look out

what the hell is this hot-air intake though?

the 1 1/2" flexi-tube that runs from the manifold to the air cleaner

so it's a sunny day outside, car has been sitting in the sun and it is still doing this. assume it's not the icing then? it's weird how it will start then die. this is weird, last time it did this it fixed itself half a day later

When I had the issue with mine doing that it was actually in the summer.

water in carby bowls. water ball rolls over jets, water dont burn, car dies.
water ball smaller, fuel gets let in, car will start.

if it was a blockage it would be there all the time. flick a bottle of meths in with the next tank of fuel. or next 20 bucks worth. see how you go.

We had a Triumph 2000 that had a similar issue except it was not weather related.

Turned out to be a rubber fuel line had a slice inside and a flap was randomly blocking the flow to the carbs.

Took 9 months to diagnose

ahh that makes perfect sense. when i tried to get it going again, it kept dying and stuff but eventually went.. i guess that i had just got all the water out of the carb bowls then

cheers
