Have you checked the brakes aren't binding?

How would i do that?

Will look at the carb, i think someone said to me once you can get Carb cleaner, is that worth a shot?

It might be, if you take the air box off and poke the choke flaps you should be able to see if its black and clogged up.

I was thinking more along the lines of the accelerator pump gasket.

If it's anything like my old Fiesta it was the air flow sensor that was causing problems with lack of power/flat spots/inconsistent accelleration. Not sure where it would be for your car but a quick browse in a haynes manual should locate it for you.

I don't think carbs have those mate.

My mistake, was on laptop when posted so had pics disabled, now I see the carb

Depending on what carb (some sort of weber I hope) you would buy a rebuild kit that contained new gaskets, strip the carb down and clean it all with cleaner and just rebuild according to the manual.

Absolutely. He could just get a can of carb cleaner though. Switch the engine on, rev and spray.

Got some videos and pictures. Need to find somewhere to upload them. Will reply when i've done it.

For now here are some pictures of what i believe to be the carb. The flap looked to always be pointing almost vertically down, and sometimes, just pointing down all the time, should it be doing this? Looks clean down the pipes though...

One below shows a pipe that connected to Manifold? and air filter, is split!!! Bad??

OK Videos are 5MB each, and i have no Software to compress them at the moment (*.mov) files. Going to go to Halfords and get the heynes manual and a possible replacement pipe if they have one.

Agent_Smith357 · 5 May 2006 at 19:06

That pipe is justs directs hot air from the manifold to help with cold starts.

The corroded device on the side of the carb, with the water pipe connected to it is the autochoke unit which controls the 2 flaps your describing. These often cause problems as Lashout said.

This should cover the theory of carbs.

That pipe provides hot air from the exhaust manifold for the choke...I think...not a lot to worry about though.

Lashout_UK · 5 May 2006 at 19:56

Aye, provides warmer air from over the manifold to the intake system on a colder day to improve idle

Got the Haynes manual last night. Lack of acceleration and power 'Common Problems' section does menchion Manifold pipes/hoses and the Engine Management System.

Will replace the broken hose this morning and see how it goes, after that you think i should look up the choke? What would i need to do there, strip it and clean it? Is this somethin i should attempt or could it break my car?
