I need a rebuild on my 5k carb.

 

instead i was just thinking of upgrading, but I'm not sure what to.

 

40Dcoe or 32/36 webbers or what else is there?

 

if any one could give imputs that would be great.

What is stuffed on the 5k carb? Re-build kits don't cost alot. Also I think I have seen some new carbs on egay

well i can get a rebuild kit for $40 but i was thinking instead of rebuilding just upgrade the carb because I'm looking for more power.

I'm not entirly sure, the car is chewing upalot of fuel.

 

i got 350 ish kms out of a full tank

Webbers will definately see to it that your fuel consumption worsens. If you want full control of fuel usage I would get 1 1/2 inch Twin Su's.

There are a few people on here who really know thier stuff about them. Those webbers were designed for 130HP and up motors. If you are really keen on new carbs, have a shot at pulling apart the 5k carb. There really is not alot to them. You could even pull out the jets from a 4k, that would suppress the fuel usage.

yeah I'm pretty well mechanicly minded, wouldnt 4k jets give less power therefor pumping less fuel.?

You have to think of it like this. The carb does not give you horsepower, what it does is mixes the air and fuel as best as it can and the power the motor makes is

directly realted to this. So getting correct jet sizes to match the flow of the carby and to what the engine needs is essential. The reason I mention 4k jets

is that over time carbs tend to wear down, jets get just that tad wider from errosion thus giving you a rich fuel mixture, by going down to 4k jets (which are barely smaller)

you get that same effect on errosion but because they are smaller and have been slightly erroded bigger you can get quite lucky and get a great mixture.

 

I am actually running a 4k carby on my 5k at the moment and the fuel ratios are very close to being spot on. I think even from factory the jets were allready running rich.

It really pays to play around, pays even more to make an air fuel mixture display!

twin 40dcoes done the trick for me, gave my 4k heeps heeps more down low torque

throw the 5k carby as far as you can! get a 3k pre pollutuion carby and rebuild that

I'm also running a 4k carbie on my 5k, have not had a problem with it and i can't fault it.

 

In the processes of getting my 40mm solex's re jetted to suit as soon as that happens i'll whack them on and give you a verdict.

3kB twins for the win. Worked great on my 5k

thanks alot guys ill havea look into some of your ideas.

 

" throw your 5k carby as far as you can!"

laughed my ass of man

cheers bud

what would i benefit from doing this, apart from a bit of arm exercise.:P

you need to look at air flow when using smaller carbs. i had the 3k carb and big port manifold on my moderately worked 5k and it got plenty of fuel when winding the mixture screw out, but the air flow was severely limited due to small thoats.
