loss of power

[81_vh_holden]

i have a VC commodore 253 V8 and i am having a bit of trouble with the engine when i start it up it's idoling a bit rough and when i put it i gear and go to take off i loose power and have to put the clutch in to stop it from stalling.

Any help would be great

Thanks James

carby could need a slight adjustment, also is your choke working properly?

 

[Not_An_Abba_Fan]

If it's only doing it cold it is probably a choke problem, if not then I'd say you have a vacuum leak. What carby you got?

 

[craigvk]

Do you have a Stromberg or Quadrajet? Sounds like the choke isn't working properly. Mine does the same thing and gets warmed up eventually.

i have a 4 barrel carby but not sure on brand i will have a closer look on monday because i wont be here over the weekend. yeah when i give it a little rev it sounds like it's sucking a whole lot of air like to much i think.

I'd look your air cleaner seal if it has one, maybe other joints and seals around the area where the noise is coming from.

Little leaks if fixed can solve major problems.

it could also be your fuel pump, if it dies when you try and drive. thats what mine vk does when i have little fuel in the tank.

She could either be having the problem also if..

a # Shes running cold
b# Idle on the carby is abit off.
c # Choke.

 

[craigvk]

Goon, A & B of your answers won't make the car run like his and mine. I would bet money it would be the choke because mine does the same thing. Thank goodness it's summer or I would be waiting forever until my motor warms up until I touch the throttle.

If the idle was a bit off, it would let you drive it fine but would just run like a barge on standstill. If it's cold, same thing but the choke is there to comfort the cold.

OP, what do ya reckon'?

my carby is a rochester quadrajet... still the same case?
