WEBER 40 - 914-6 or 911T Carbs, They seem to be the correct carbs but not stock? Options

[ctc911ctc]

1970 914-6 all stock

All,

I am down to the last thing for this engine re-fresh: CARBS

They seem to be in very good condition and since they are missing the Porsche factory mark I am guessing that they were 'cored' on a rebuild sometime prior to my ownership

OR

Are 914-6 carbs NOT market like 911 carbs are???????

Anyway, I have not gone too deep since they are in great shape - the gaskets seem good, the floats are the brass kind but in perfect shape, the bowls are very clean,,,,,,

Can I get some direction on:

1. what to look for in a recently rebuilt carb
2. where is a good reference for setup prior to installation

Any other opinions would be well received,

Thank you Teeners

I don’t know what stoddard was doing

Assume they were increasing vents from stock to improve the top end


But like Mark posted.
I run IDS carbs on the race car for higher rpm fuel enrichment (jetting)
They have an extra passage to feed an aux enrichment tube at high rpm

Believe that carb was only made for 2 years

I had Paul Abbot(sp) convert a set of carbs to IDS.

They work so well for high rpm
I can see the AFR go lean at 5k, then fatten up all the way to redline in real time on the track
