can't figure out carb linkage for Weber 38

[kerb12]

Hey all, first time posting here but I've been following for awhile now, and it's been a huge help for the 200 rebuild in my 66 mustang. I'm at the last step and putting on a Weber 38 DGES carb on the classicinlines 2-1 adapter, but I'm a little stumped with the linkage. The pedal linkage moves up an down (up when pedal is pressed) but the carb end is front to back. How do I get an upward pedal linkage motion to translate to a pull towards the firewall to open up the carb? Any advice?

You can use a bell crank to change direction or you can also change it over to a cable throttle linkage.

Thanks. I was thinking about switching to a cable, but then I'd need a way to have it control the kickdown for the C4 too... bellcrank seems like it might be a better idea, I'll look into that. This is my first time trying to make a carb linkage though, so any chance anyone has a pic of how they did it?

Ok, so I ended up having a local shop make me a linkage. Here's how it ended up if anyone else needs a reference. It works really well, nice smooth pulls.

Nice job

The above is a copy of the 1974 to 1982 Cologne V6 linkage for the 32 and 34 Solex 2-bbl, a Weber workalike carb used on European V6 stuff, like the German Ford Capri. I had one on my 1982 2.3 V6 Cortina.

Although they look different, the 38 series Weber and the 32/36 and 5200 variants use a similar long arm linkage. Here are three other solutions. I do like the above solution best.

Piece of cake. I use the lost pivot point, the handed nature of the European version of the Weber DGA used in the Ford of Europe Granada/Taunus/Cortina/Capri/Sierra, and the years of trawling Ford Six dot com contributors which allows me to use the stock 16 degree stud slew.

My influences were log headers like 75greenmachine, Danielson, bigredraza, and especially anyone who fought with the Stovebolt adaptor, and left the carb in its wacky position. Props to you all.Linc's 200 showed me that its inevitable that there will be a jog jam if you want 350 horsepower of energy to flow through one hole, and he nailed the problem, and made me think along the flow efficiency maximum the David Vizard espoused when a Log headed intake was used on a Pinto 2000 engine that outflowed the stock engines intake yielded less power due to awful inter cylinder flow efficency. Just like our log head engines.

But I digress. Care of Mr Salazar, aka bigredraza

The lever operated early round bodies hold the key



Mine is mounted that way, but the 32/36 DGA carb linkage and secondary position is reversed when compared to the 5200 Holley Weber version. That allows the linkage to work when its arched over the log manifold. A case of fitting the carb before the log.

Albert Pennello used the 5200 Holley Weber, which is a handed 32/36 DGA Weber. His Clifford set up was like this,

Cliffords adaptor eliminates the 16 dgree slew, but the linkage with the 16 degree slew, and the reversed image 32/36 DGA versions on the Weber, allows the linkage to canterlever off the centre of the log like it was made to be.

Landons Stovebolt adaptor put the carb on a 16 degree pitch when used without the stock water heater intermediate part, and it then lost the pivot point.
