Webber carb on an inline 6 Anybody done it?

[casadejohnson]

I have read about installing a webber 2bbl carb on a straight six many times but I have never seen one in person or talked to anyone who has done it. I picked a webber up at the junk yard and plan to rebuild it in the next few weeks. If you have done it, how tough was it? What adaptor did you use? I know there is info out there on Fordsix and other sites but they are mostly Falcons on Mustangs.

I have put progressive Webers on VWs with fair results, (currently have one I have messed with and now it is too rich, but that is another story), I have put them on Mercedes Benz with good results. They will work and fairly well, however I feel you will want more than a progressive 2bbl will give you. Now throw on three Weber 40 IDFs and you can make it scream. Some tuning involed and a special intake of course.

We put one on a 6 cyl jeep my son had a few years ago. Worked fine on the hwy, but it was useless off road. It could not handle inclines.

I fellow I used to know from Corcoran, MN raced Broncos in the seventies, usually with 300 sixes for motors. He ran three Webers on these with pretty good results, if I remember right. They worked better than the six Tillotson HD pumpers he once tried, anyway.

Somewhere there is an article on installing 3 sidedraft Mikunis on a 170 or 200 6 holer. Wouldn't be much different for a Bronco , Falcon , Muustang as they used an integrelly cast manifold. I think sizing and jetting would be a obstacle,but could be done.

Must be my problem too! I put a Holley/Weber 5200 and while it gave a definite performance boost, I have noticed on a few inclines, it's died and acted like it was flooded. I used a Stovebolt adapter and it raised the carb just high enough that the stud for the breather put a slight dimple in the hood. I installed a body lift just after that so now it has plenty of room. Had to cobble together a mounting bracket for the the throttle cable. Couldn't use it in the stock location. Overall it was a pretty simple install.

edit* I think I remember having to do some reaming out on the holes of the Stovebolt adapter for it to fit right. Might be worth spending the extra for the Clifford adapter.

I have to do a little more research but I think this carb I have is a model DGES. I don't think this carb is progressive. It seams that the primary and secondary are opening at the same time and at the same rate. If I'm correct about what I have, this carb is rated at 360 CFM. Is this thing gonna be too much carb for a 170 thats basically stock?

I say give it a try, I really do like Webers for tunability. My user name is because of one (48IDAs) and my dog's name is Weber!

 

[casadejohnson]

I'll be honest, I don't know a hell of alot about the Webber. I just know that its a somewhat common conversion on inline sixes and found one on the cheap so I snagged it.

This is the carb I have. Its marked 38DGAS but this has an electric choke which webber says is the 38DGES it is a syncronized carb not a progressive carb. Webber refers to it as a "performance" carb and sells this thing for $380. I think I did OK at about $20.

My son's Datsun mini truck had a Weber progessive 2 Bbl that would flood at the most inopertune times until we put on a fuel pressure regulator set at 3lbs.

You jogged my memory. The regulator may be a good idea. I was running dual Weber ICT's on my dune buggy and Weber suggested running no more than 3lbs. pressure. You might check the Weber/Redline site for recommendations on your particular carb. It was a VW, but it made a world of difference.

Edit: I just checked Clifford's site and all their Weber kits come with a pressure regulator.

 

[casadejohnson]

I did read on the webber site that fuel pressure is very important. It sounded like fuel pressures below about 2lbs could be a problem as well as having the pressure too high. If I remember correctly, my stock mechanical pump runs in the 6lb range. If thats correct, a regulator will be a must have to get this working. I was very pleased to find that rebuild kits, jets, and tuning info seems to be available for all the webber stuff. Now I just need an adapter and an Air Cleaner for it!
