Quick question - when setting the float level on the WA-1, which edge of the float seam do you use, with the top inveterted, the upper or lower edge? The shop manual picture isn't terribly clear.

Thanks

    I just did mine and I used the solder joint to measure.

    It seems the Essex Terraplane has also a WA-1, it's a small sigle barrel carburetor I will have a look if i can find something in the owner manual :unsure:
    If yes I will reply else we have the previous answer/experience sofar.:)

    Okay, that's what I used too. Just making sure I saw things right.

    Be aware that this is a setting that was okay for 1950,s gasoline, and with today's lighter fuel you may have to lower the actual level by about 1/8" if your car runs too rich.

    Thanks, I was going to start at a 1/16, I just wanted to make sure I was at the right start point.

    Do not lower that float for if you try to pull a long hill up to 7,000 feet you will have a fuel starving problem. My 968's on my twin h engine is set to factory specs, 1/2 inch to upper float seam with bowl cover inverted, and have climbed to 15,000 feet and drive across this country with a sun visor at 80 to 90 and average 22 on long stretches. My Oklahoma City trip in 113 to 115 temp, covered 3,300 mile in traffic, road detours, city and long grades and averaged for the complete trip 16.7 MPG. If carbs set right, then you have a motor problem. I set my valves cold at 14-17 for trips under 1,000 miles and when I go across country I set valves cold at 17 and 20. So far have driven 130,000 mile since rebuild and still have 130 pounds compression. Walt.

    Walt, any recommendations for a high elevation set-up? I live at around 5000-6000 ft. and I'm used to leaning out my Edelbrocks about 6-8% from factory. The 48-49 manual lists leaner rods for the WDO, I don't see a list of leaner rods for WA-1's. Or am I chasing my tail?

    The 48-49 Hudson 8's take Carter #648s, with base number 542 stamped on it. Standard metering rods are #75-607 and at your elevation you need 2 sizes lean Carter #75-628. Almost impossible to find today, so close up the meter rod jets from .086" to .083" and you will be OK. Make sure you set meter rods with Carter Gauge #T109-113. Leave the rest as when new. The WA-1 standard rod is #75-834 and 2 sizes lean is #75-862, here again standard meter jet is 0.1015", so close up the jet to 0.096 using the jet from Wasp and Jets 53 to 56. Leave the rest as standard. Walt.

    I don't suppose you would have a pair of those 0.096 WA-1 jets, would you Walt?

    I'll be going to my warehouse tomorrow and will check and get back to you. Walt.
