Hello all,

A mechanic at my work has offered to sell me a 32/36 webber at a reasonable price.

I have searched around abit on the sight and the FAQ/Wiki on this sight under "Carburettor" say this:

 

 

One of the easiest mods for these cars is to change the carby!

 

A Weber 32/36 DGV is the most common aftermarket downdraft around. Usually you'll need to jet down a carburettor like this, unless someone has already done the work for you, or you have a fairly modified engine. For a 3K/4K, start at around:

 

130 mains

170 air jets

50 idle

I have already purchased the jets the wiki suggested and an adaptor plate for the 32/36

 

A few days later after reading that I came across the "how to build a tough K motor" wiki, it says

A 32/36 DGV from a 2L Escort is too big, unless you can get one of the rare ones with small primary throats. The stock carb is 27/27 (or 27/32 on 4K onwards), so anything from there to 32mm, with primary chokes between 20mm and 25mm will probably go fairly well.

My question is, should I buy the webber and rejet it, or keep looking and find a smaller webber.

I would prefer to buy the 32/36 because of the price, condition and the fact that i have purchased the jets already but if you think it will run like crap I wont bother.

 

My engine is a completly stock 3k-c with the Dual plane, dual outlet style stock exhaust manifold

 

Any help would be appreciated, or even a link to an existing thread you know of.

 

Thanks

I am in the same boat,you have asked all the questions I wanted,subscribed

Well, really mate, you'd be better off putting the money towards a set of extractors.

 

The webber is a little big, I have one on my 4k, and it's lost alot of response below say 3.5k, but one you get up in the rev range, its sweet.

That said, my 4k's got a cam and extractors etc.

 

I get the feeling on a stock 3k you'd be running pig rich, hate it, and swap back to your stock carby pretty quick.

Buy it cheap, sell it on here & use that money for a small Weber or SUs

Has it been jetted to suit your application?

 

Correctly tuning a carb WILL make a world of difference.

 

We got a 32/36 running fine on a stock 3K. Not that much work.
