If you add a resistor you can lengthen the on choke time but you must check also for full open choke at operating temperature.

ford390, the heater in the cap is your resistor, adding a 50 watt in line would lower the current meaning less heat. There is a "surplus store" near me that has 50 watt resistors inside a finned housing (cooling). I would guess .75 to 2 ohms to slow down the choke opening rate but whould have to check for full open when up to normal temp. Testing in the future.

Slower opening choke..............that's ME just waiting longer to push the little **** in on the dash...........LOL!!!!
My '69 and '67 have factory manual chokes.........and I LUV THEM!!!
I tried electric models before, and just never got them set the way I wanted. Yes, they are automatic and no worry. But the upside of manual is you can leave it on longer, if you want. If you need to raise the RPM to help jump a battery you can just pull it out a bit(kinda like a manual throttle), or any other type of scenario. Never had one freeze up, since I use it pretty regularly. The factory type cable is pretty stout piece(not like cheap aftermarket junk).
I always remove the choke plate from carb so I can pull throttle up alot and not shut off air supply. It starts just as easy, a simple pump on throttle and it fires up even in dead of winter.
Mark me: MANUAL CHOKE 1

Choke!?! We don't need no stinkin choke! I've been waiting for that. I had to run one (cold for Denver) winter without a choke, 4 pumps it was started, three minutes to the on ramp and the top end was lubed. The rest was highway driving between work and home. The only trick was to feather the go pedal to keep the motor running at stop signs.

When I swap to the 4v (different motor) I'll go manual. I found a real manual choke mechanism at the junkyard, forget converting the round housing.

I remove the plate so I can pull the HIGH idle up without choking the air off. If you leave the plate on, pull the choke full, it will flood out sooner or later. Mine won't, ever. Mine never stumbles, but it's a stick also.

Yes, they do work right...if that is what you want. I always hated the set up, that is why I removed the plate and used high idle cam only. Most all my motors have not been too stock, so this type of choke never worked very well for me.
That's what is great about this........to each his own.
