Holley vs. Eddy
But... It is rich. Rich to the point that stone cold on a 50 degree day, It will start and idle fine WITHOUT touching the manual choke. I am sure this is too rich when warm but I am not familiar enough to adjust it properly.
I have done the idle mix and they settled about 1 3/4 turns out on both sides.
If I do set the choke, it floods almost immediately.
Holley came off a great running 327 that a buddy had.
If I do the math right, my 318 +.030 is 323cid.
Should be bolt on right?
Or is the linkage going to give me fits?
Ditch the manual choke and get an electric choke.
When set up and adjusted properly, they run great.
Hook the positive wire to the input side of the ballast resistor (Not the coil).
Then adjust it so the choke flap is vertical when the car is fully warm.
I drove a 318 with a holley 1850 and electric choke every day in Michigan for years with no trouble. When the choke was adjusted properly, I would go out in the morning, pump the gas pedal twice, start the car, watch the oil pressure climb, then put it in gear and drive away... No stumbles, coughs, or backfires....
I always run electric choke on drivers...
FYI: Holley also has another 600 vac secondary based off of the 1850, but is calibrated for a late 60's vintage car and comes with electric choke... And it's about $20 cheaper than the 1850 to boot!!!
Here it is, the Holley 80457...

So you're better off ordering the 80457 than the 1850 and then buying the electric choke if you are buying new...
If you already have an 1850, then get an electric choke kit for it...
