Carb Freezing

[Anonymous]

What are the symptoms of carb freezing? I've heard it's a common prbb on novas with bolt-on filters. My car playing up at the mo and i'm just trying to figure out what the problem is.


My car is a 1.4 SR with weber 32/34 carb and a K&N bolt-on filter. When i get to 2000 revs in any gear the car jerks like crazy and starts to come to a standstill, this carries on until i hit 3-3500 revs. Is this a symptom of carb freezing or something else?

It's like a negative turbo when you hit a certain rev range, all power disappears :(

It sounds like carb freezing, but it could also be your leads or other ignition bits getting wet.......does it only happen in cold weather, or is it as bad when it's warm, but wet?

I had similar symptoms, but it WAS NOT the carb freezing, as it didn't do it when the weather was cold....ONLY when it was very wet....especially when driving behind trucks down the motorway, with all the spray....that's when it would happen the worse.

Check the ignition...leads, distributor, coil etc...try some damp-start. Replace bits if necessary...especially the leads.
Many people also advise using a marigold glove over the distributor, to keep the damp out.....as the rally boys do!

I've already replaces the leads and plugs. It seems to be just when it's cold. It's probably me not letting it warm up fully.

You know these bloody new drivers, they don't know anything. :D

has it been really cold where u are?? its a bit "warm" for carb freezing id say.
Have you checked your fuel supply, pump filter etc?
If it aint that your carb could be blocked.
Not likely to be carb freezing if its just started lately.

i take my filters off for the winter and revert back to the orig

i put my k&n back on the other day and mine has iced up 5 times scince (normally late at night or early in morning)
