I have a boat with duel stations ( fly brige)) the engines are 1973 chyslers 440s, I am going to install new elderbrocks.Where is the best place to get positive power for the choke? Thanks
I'd be interested to hear why you feel so strongly about this.i disagree with getting power from the coil. period.
Jeff is correct.I used the wire going to the ballast resistor. Its a full 12 volts.
ricardomarine....adding any additional load to the primary side of a ignition coil is to be avoided.
Crankbait, without sounding condescending or sarcastic, can you then explain why the auto industry (and the Marine industry) has been able to pull this off for years and years, and with no apparent issues?ricardomarine....adding any additional load to the primary side of a ignition coil is to be avoided.
Kim,
- The helix is a bi-metal spring that responds to the heat produced by the heating element.
- The two metals expand at different rates any bimetal spring can be considered a thermostat.
Most of us here are adults and we use adult like behavior. We are usually polite to one another, and we show deserved respect to one another.I am only responding to what the ORIGINAL poster said he is using. I AM NOT the one hooking up the carbs. read the original post before you pile on with your wizard advice.
Crankbait, if your carburetor incorporates a fast idle step up cam and linkage, it's most likely an automotive carburetor, not a Marine approved carburetor.
That is correct! I believe that we all know that.i am not the poster that is installing the EDELBROCK carbs.
................ so the choke vacuum unloader can pull the choke off high idle and open faster...........
the vacuum unloader can ONLY pull open the closed plate @1/8 inch on initial start up. it cannot overcome the tension of the choke coil spring when cold.....no matter how high you rev the engingine, or no matter how much vacuum you apply to the vacuum pulloff pot. it will not happen. the vacuum pulloff is designed only to eliminate a full choke condition at inital start. if you notice, later emission q jet carbs, have two vacuum pull off diaghprams. the initial is to serve as an unloader......the second, is to act as what you you currently think the unloader is supposed to do.....is to help pull the choke off quicker. now a days, that second pot has been replaced by a heavier fulcrum weight.(only when a carb was used). it was more cost efficient, and the vacuum pulloff was prone to leak due to the high engine temps.

- This tidbit is irrelevant. Initial startup condition doesn’t change whether you have the choke wired to 9V or 900V.
- If I was concerned about emissions I wouldn’t have bought a boat with two V8 engines that burns 20 gallons of fuel an hour. I would have bought a Prius.
Although I try to avoid this, I usually wear a skirt and sweater when I drive it.Prius?? time for comedy ..................... http://www.youtube.com/watch?v=RL4wfilTe-o
... and if I recall, it worked very well.The reason for this, The choke will not heat up until the engine is running. Ford did this with a lot of the carbed Vehicles.
