I rejected the Langdon's setup because, even though it was praised by many here, I thought it looked ugly. Kind of like a Frankenstein conversion. I didn't like the look of the adaptors. I thought the carbs looked all wrong for the year and engine. I hated the air cleaners. That doesn't mean Langdon's isn't for you. It just wasn't for me.
So, I run two Model B's with no chokes at all. The only problem I have is low gas mileage because, well, I can't seem to keep my foot out of it.

Here's some pics:

I know everyone says you have to have heat to the intake and you have to have chokes. Apparently that ain't true in Texas. The truck runs like a scalded dog and doesn't hesitate on takeoff at all.
It's your truck. Do it your way.
