I have an 083310, secondary plate. Floats both ends. How are the float levels adjusted properly. Let me see if I got this right. remove the sight plugs and see if fuel poors out, which would mean-too high. ??? And by turning IN the screw on top would lower the fuel level??? I read a post once that said you can leave these float level windows open while checking to see if your level is being corrected. That didn't sound right to me... If ya got the motor running you'd have fuel pooring out. Do the plugs need to be put back in after each adjustment and than pulled again to see if fuel runs out???

Also, most of the carb i'v seen are not completely level. They seen to slope down in the back. Is this correct also???

Thanks guys

take the bowl off , hold but up side down and set the float at level position is the fool proof way and the best base line ..... but yes , the fuel should just trickle out of the site plug as long as things are somewhat level engine angle and its not a 2x4 with carbs backwards mounted like factory ford intakes .....

I set mine the same way but I don't know what the 2X4 carbs has anything to do with looking to see if fuel trickles out when removing the site plugs.Mine sit level.

Holley carbs have the primary sight plug at a different height than the secondary to reflect acceleration and mounting angle differences. The backwards mounting on 2x4 carbs screws that up. Level to the inside top of the bowl is the right place to be...

Barry I know and I set mine level with the top of the bowl.back then a lot of guys made jet extensions especially if your car had slicks.My LWG of course didn't but my Fairlane did and I made them for it as it launched pretty hard and carried the left front wheel almost to the tree and made a copper vent tube between both vents with a few holes drilled in then to prevent fuel slosh from getting in the venturies.Not like Battlestargalaxie's of course.I could see over my hood,lol.

Thanks guys. As usual - good help. Love the youtube.

One more question thou... All the motors I have seen are tilted down in the back which makes the carb deck also tilted somewhat down at the rear. Which sets the carb tilted lower in the rear. Is this common or should that carb be level. Now I have seen some of the intake manifold decks casted higher in the back, I'm assuming to make the decks level. BUT from what I see on most motors are the carb still setting lower in the back. In fact, I spent the whole day at the bone yard picking up stuff and i made note of all the motors FEs and others, all tilted down somewhat in the rear.
SO, my question is: should the carb be level and how do I achieve that, OR,,, is that just normal.
Thanks, Fritz

A friends dad made a set of plugs for the rear with a hole drilled in the middle. He would set the front like normal and the back would trickle our of the hole.

I at one time, tried to use those clear plastic screw in sight plugs but the gas melted the darn things. I had fuel pumping out all over the motor. I was real lucky it did't catch fire. This was a few yrs back so maybe it was just the type of plastic or maybe the alcohol in the fuel. Do the ones they sell these days work better or should they even be used?
