Thanks for the info Darthweber, I sent a pm to him..I also found ACE ( air cooled engineering) they had great feedback also. So we will see what they say, Thanks again got my fingers crossed .
You were correct on the 28 venturies.

Send it to Mark Harney http://www.carburetorclinic.com/
For velocity stacks see my post above or let Mark take care of it.

| If that's a shortened buggy you could probably swap jets without leaving the driver seat! Looks perfect for the buggy, be interested to hear how it runs. If the carb isn't too dirty, could you do with a soak, blow it out, and overhaul kit yourself? |

OK I got it . It is a 40 DCOE-18 weber Itialian made.
Specs:
Main Jets: 120 (130 - 140)
Air corrector jets: 195 (180)
idel jets: 50F13 (55 - 60)
Pump jet 50
Emulsion tubes: F11 (F7 is better I think)
venturis: 30mm (28mm)
What sould I cange to get it to run on a stock 1600 motor (all new mexican motor ) |
Those would be my guesses to get you close but I'm no expert on single carbs let alone unusual single side draft carb setups like yours. Others will come up with better advice no doubt.
I believe a problem you might encounter, and a reason why this type of setup wasn't real popular, is because a side draft carb is supposed to be mounted perpendicular to the direction the car is going. This means the float is less affected by stop and go motion or hard acceleration and braking. You might be able to get around this by using a ball type inlet valve instead of a needle type. This limits the float travel and controls fuel levels in the float bowl and jet wells better.

Sorry, all I remember is a K&N type filter, not what was under it.

| Looks like the manifold and carb bolt together. I have a car craft manifold that runs oil through it and it bolts to the carb and it's welded to the turbo or you have to run a hose and clamp to connect to the turbo. This manifold is designed for the carb to bolt directly to it. You could build a spacer of some sort and run oil beneath it to warm it. |

I had one of these setups on my 1600+ DP Beetle back in '81. Big jump in top end power for autocrossing, but I never really got it jetted right for bottom end. I didn't worry about heating the runners. It was summer in central Texas. It looked kind of dumb on my Beetle with the deck lid off, but it should look good on a dune buggy. DCOEs are great carbs. I used to put quite a few of them on old MGs, Triumphs and Datson Z-cars to replace emission Strombergs. Every bit as tunable as IDFs and the jets are easy to get to.

 The manifold is facing outwards for the sidedraft but still needs the piece for the oil cooling to the Turbo connection.
Three pieces....Carb....center section for the oil to go thru...Turbo itself.
Center section needs hot oil or will ice up and sweat. |

You could still blow through it with a T3 or something.

Wow, you're right, the manifold was welded the wrong way! The carb will interfere with the fan shroud.

Stupid question here.
How does a person run a 40 DCOE SIDE DRAFT carb on a vertical intake manifold?....suppose a weld job could solve that issue.
I have the same carb on my 1776cc Turbo engine thats over 20 ys running. |
