Seems with cooler weather I'm getting some PMs about WCFBs, choke settings, cold starts, sticky choke pistons, etc.. Here is a short video from this morning of how my clones work. The audio gets a little choppy once the car starts because of the cell phone camera "clipping" audio but the car runs perfectly.

I don't touch the gas pedal inside the car in this film...just set the choke by hand with one blip, and, blip it by hand again to take it off full choke.

To adjust the choke here in Florida (on a typically cold morning with a cold engine) I loosen the choke housing screws, hold the throttle linkage wide open and rotate the black housing until the front edge of the choke plate blade just touches the front of the primary bore of the rear carb. Then I turn the housing about another 1/8" to 1/4" in the same direction and tighten the housing screws.

Enjoy!

I've never see a carb choke go from full on to full off in 9 seconds.

I wouldn't say it goes to 'full off'...but this is how mine work (my 'real deal' dual quads act identically)... These carbs tend to run rich anyway so that's enough choke I can drive right off in the mornings with no bogging.

It IS Florida however...If it weren't 65* here it would stay on longer I'm sure...
Adjusting the choke on a colder morning would make it release more slowly; maybe another video later in the winter...

I thought Florida cars were choke "DELETE"

Up in the Northeast it's in the low 60's today. When the car is started you do see the choke butterfly move a bit initially due to vacuum pulling against the choke thermo spring (if I blip the throttle the butterfly still stays partially open till the temp come up), but it is not supposed to fully open until the heat from the engine makes it's way up the choke tube to heat up the that spring which expands it to a relaxed position where the butterfly is held open purely by vacuum. You could take the choke off in 60* weather and it would still start right up. Now when I drive in the winter months and it's 30* (before they salt the roads) you really need that choke and it takes several minutes for it to start to open. Nice video. Pilot Dan

Choke? Who needs a choke?

I never hooked up the chokes on my 2X4 carbs. 1963, it got to -30* here. Coldest day ever here and I think coldest winter for average temperature. My car started and ran everyday. It had to start fast as I didn't have enough battery to crank on it.

Even today, I have non-functional or partially functional chokes on my old carb cars. On purpose.

Frank, I love read (or watch) anything that you post.

Please keep the good info coming.

Best Regards,

Thanks.

Yes, I've driven chokeless cars even in the horrific Pittsburgh winters...its no fun and requires 'babying' the car for the first 10 minutes of driving and lots of 'feathering' of the gas pedal...
Probably wastes more gas than the choke and a fast idle could ever do.

Been there, done that, got the T-shirt

I've been asked to do a video of how I adjust solid lifters on my '61.

That'll bring the critics out in droves I'm sure...

Slightly off topic but I really like the look of dual quads and the sound. this maybe my next investment.
