Hey I'm about to get a new edelbrock carb. Does it really matter if its a 1405 or a 1406 I know Tue main difference is the 1406 has an electric choke and the 1405 doesn't. So if they would both have the same performance it won't really matter, right. Or is there more to it than just that ?

 

about the only sure thing I will say is the electric choke is a real bastard . they work nice when they are new but that fades fast .

 

hmm... not exactly what i want to happen. I'm putting in a GSL-SE, long story why.. but i don't have the stuff ran for a manual choke, but it that's the best way to go I guess that's what I'm going to have to do, thank you!!

 

Electric choke is a pain in the ***. ^+1

 

To start with I'm not saying they don't work . when new they usually work fine providing they get proper voltage , some require full 12 v some require a resistor in line to control voltage .so the heat spring doesn't melt down that would be in the installation instruction , they don't just require voltage when starting to slowly open choke they require voltage continuously to regulate and keep choke open .

If you are working on the engine with the ignition on and not running you will find on some models of e choke that the choke fully opens and will not close until the choke mechanism cools down .

After a time the choke coil ( spring ) becomes weak and needs to be replaced ,they actually turn a blue color from the heat created by the voltage feed . it doesn't happen overnight but it does happen .

The electric choke also requires a choke pull off ( usually vacuum operated ) to open the choke from full closed on start up to prevent flooding which will also give problems as time passes .

the choke operation and the choke pull off need to work in sync to provide proper operation so when one gives problems the other might possibly need setting also.

The manual choke with a good cable set up ( the cheap **** isn't worth taking home ) push the pedal down a bit pull the choke fully out ,pump gas pedal if needed start the car . Push the choke in a tad until it runs easy , let the little engine warm up an bit pump the throttle to take the engine off the first step of high idle and push choke all the way in ,, you may need to keep the choke on a little for a few blocks until the engine runs without stumble . there are a few things during set up you need to watch ( like no sharp kinks in the cable it must run in a smooth loop . Holding brackets need to be mounted so there is no movement to them so the choke actually moves when you pull the choke or push it in . The worst thing that can happen is pulling the choke on without depressing the gas pedal a tad ( this won't allow the carb to go on fast idle and puts unnecessary stress on the cable and brackets .

I can't stress enough how important it is to buy a good quality cable set up DON"T BUY THE FLIMSY LITTLE **** YOU WILL HATE IT .

I think most of the guys that have went to a manual choke have nothing but good to say about them IF they are set up proper . I would be willing to bet that 7 or 8 out of 10 of the old school guys run manual chokes.because they work the same all the time . this is not JMO but fact . like I said on an earlier post with someone , I hate E Chokes as much as Aaron Cake hates carbs . Hope this helps ... Gerald m.

 

The 1406 is jetted slightly leaner.
