I'm looking to renew the carby & inlet manifold on my '72 1300 standard beetle, as the heat risers have rusted through (I have heaps of trouble with massive flat spots once the air temp gets cooler) & the carby is now 35yrs old & drawing its fair share of air around the throttle shaft.
Investigations have shown that new standard carby & manifold is going to cost me between $400 & $500 so I thought I might aswell upgrade to twin carbies.
My options as far as I can see are;
1. 40mm Kadrons
2. 34mm ict Webers or Empis
3. adapt a set of Type3 carbies
Can any of these combos be set up to work correctly on a 1300cc engine?
I am leaning towards the Kadrons as they will provide more room to move when I am ready to increase engine size, but I am afraid they will be to big for a standard 1300.
The Webers would maybe not as beneficial on a future larger engine & the type 3 setup will probably be the cheapest but will bring with it the same wornout carby issues that I currently have.
If anyone can give me some advice it would be most appreciated?
Cheers

surely someone would have a good SH one...? Big carbs on a 1300 is a waste - but so is $500 for a new carby!

Thanks for the input guys, I should have said that as soon as I have need to crack the engine apart (currently its solid apart from this issue) I will be going to at least 1600cc so that is why i am thinking of getting the bigger carbs now & rejetting etc when I increase capacity.
vw54, my existing manifold is a single preheat tube, but it is for a 31pict 3 carby so its got a smaller opening & bolt spacing is closer together than the more common 34pict 3 manifold.

the mainfolds are availble new if you need one, make sure you get the quality German rubber boots if your replacing them

Hi
The 1300 twin port also has smaller alloy cast ends as well and the rubber boots are smaller also. Might be better off getting a whole 1600 manifold and carb, seeing as your going 1600 anyway.

Thanks Steve, I didn't know that, I have 1600 end castings in the shed so I'll use them if I go that way.
an anyone confirm nor deny the fact that 1300 twin port heads have smaller valves &/or ports than 1600? I would assums cam would be different also?
Where can I get a carby rebushed & are the throttle bushes the only part that wears out that cant be replaced simply by screwing them off & replacing them or am I missing something?

SAS,
I believe the 1300 valves may be smaller. I seem to remember my old Sealed Power Catalog lists different sizes. I'll see if I can dig it up, or get brave and crawl through the underhouse pile to measure up a 1300 head I have.

SAS,
I measured 35.5 x 32 head diameters on the heads that came off my AB block 1300 TP. Same size as a standard 1600 TP.
