heres my latest set i built for my car.... not quite finished yet

Wow, that does look good, would twin 1.1/2s be a better bet for my 1380 rather than the HIF44 that i have got on it at the moment, when i got it dynoed it pushed 99 bhp at the flywheel .

That I couldn't tell you but I'm sure someone will be along to answer...:0)

They are more or less finished now with stainless heat shield etc

Cheers james

The carbs are silver under the muck ..... Il give you a tip..... Use a brass brush as a wire brush is a little too harsh

Wow they are very nice could you tell me what spray you used to paint the carbs silver please because as you can see in the phots mine are very old and messy

[jpw1275]

I normally give them a good soak in gunk for a day or so after stripping them down completely

Cheers james

And does that make them have that awesome finish?

It's only because they have oxidised, with a good brush they will come up fine....... Mine start out like yours....:0)

So wire brush them then then put them in gunk engine degreaser.

[jpw1275]

i told you the wrong way round .... put them in gunk first then use a brass brush ( like a wire brush but brass instead)

cheers james

[jpw1275]

or you could cheat and buy a silver spray paint specially formulated to use on carbs... it comes in silver and bronze.... you can buy this from frost and they also sell it on ebay under carb laquer

you would still need to gunk them first to get rid of oil etc

cheers james

  If there is as much corrosion inside the carb suction chambers around the pistons as there is outside they may well be scrap.

wow after seeing all these pics of twins, makes me want to put mine back on!

to be honest i had a pair that had corrosion on the inside and once cleaned with autosol worked a treat...:0)

[Dan]

  It depends on the extent of the corrosion obviously but if you have to remove so much material in cleaning or there is so much pitting that the seal between piston and suction chamber is leaky they will be no use.  Especially in twins where the piston drop times have to be fairly similar across the pair.  A new piston and suction chamber is very expensive and would make it cost more than getting a better pair to start with.

 

  When you assemble them make sure you are using Mini Cooper spec parts rather than Midget or similar so that everything is at the right angle when installed.  Check they aren't Midget carbs to start with as if they are you will have to swap a few parts that will not be included in a normal overhaul kit.
