Almlost ready for the carb upgrade. Still a few questions...

Hi,

My '65 coupe currently has a '68 200ci inline 6cyl engine with a 1bbl carburetor. I have a 2bbl 5200 carburetor that I would like to replace it with. I have the correct adapter and air cleaner. I have several questions regarding to the upgrade:


How should I prepare the carb after I install it? Do I need to prep it with gasoline?

The carburetor has an electric choke and I need to hook it up to a 12v source. What is the best place to connect it and where do I find the correct wire for the connection?

I have never done any work with carburetors before and I do not know how to tune them. Any tips and advice would be greatly appreciated.

Thank you,

Justin :wink:
 
to prep my weber 32/36 i has to crank te engine a little until the fuel bowl filled up. then it started up and i first checked the timing (but i also installed a pertronix with the carb so that was necessary). once the timing was close i adjusted the idle mixture. you turn it in until the engine starts to die then turn it back out a 1/4 turn at a time until it sounds good. supposedly you should not hav eto go too far. i think i readlast week on this forum that you can tune the idle mixture with a vacuum guage as well. then i adjusted the idle RPM screw, it just sets the zero point throttle lever.

by the wa the engine should be warm when you do this.

there was a big discusision on this board about where to get switched power for the electric choke. i don't know how much current they draaw, on mine i put in a relay for an electric pump, so i just hooked the choke off the relay output. i switch the relay off the coil since it's so easy to hook up to. but it sounds like people don't like the idea o ptting the electric choke directly to the coil? i guess it might rob your spark of some power.
 
Thanks for the response. I posted a question similar to this before and I got several different answers as to where I should hook up the electric choke. I might try to hook it up to the black terminal on the alternator. My problem is that I do not know what kind of wire I need. I have no experience in electrical work and I do not know what kind of wire to use for the electric choke connection.
 
i think you get some 18 guage wire it should be fine but i don't know for sure. it depends on how much current is running through the choke. if it's an amp or so i think 18 guage should be ok. if you want get a little bit thicker wire like 16 or 14 guage

maybe someone else knows better?
 
Too thick of wire isn't going to hurt except for the slight weight it adds.

Too thin of wire will burn up when too many amps are passed through it. Since you'll only be running 12V, most any insulated wire will do.

Just go to home depot and pick up some 14 gauge and you'll be fine. Thinner would probably work fine, but this way you'll be ok for sure. You don't need to do any engineering for a wire like that, just oversize it, wire is cheap.

I would like to attach the choke wire to the alternator but I do not know which part of the alternator to attach it to. Does anyone have any pictures that might help me? Can I solder the connections? Thanks :wink:
