Parts overview and assembly of a quadrajet carb.

[@heartbeatstorm983]

Just to let you know,, others have stated many times,, not to fish the hook in the holes..

[@MySonMarlon]

little clip from needle must not be hanged in the holes ......it must just hang from the inside out on the float.

[@smokeydabeecharlescoleman8365]

Agreed

[@noputtbob]

If I recall, The 1/4" float level should be measured at a point 3/8" in from the end of the float because it is on a slight angle. Or, am I just being picky? Don't get me wrong. I love this video. You did a nice job. Bob

Thank you for these videos!! I have a 66 Hatteras with this exact carb. My fiberglass tanks were severely contaminated by ethanol gas. Needless to say the carbs were full of a syrup looking goo which was the resin of the fiberglass. This video was extremely helpful. Thanks!!! Do not use ethanol gas!!!! Call your Congressman if you are a boater.

@ like 8:45-8:50, should the rods be able to swivel like they are? or should they stay straight?

[@randellmd]

Yes i did. Just make sure it kinda snaps in. you might have to use a dull object (screwdriver maybe) but be real careful not to press too hard.

[@randellmd]

Trying to reassemble the meter rods but it won't stay in when i snap the little round thing in place.

This video is very helpful the way he explain himself and how he demonstrated the parts in good detail way made my float adjustment really easy

[@LostInMadness220]

did your power piston ass. have a check ball at the bottom and spring on top of it?

[@justieml8]

Excellent video man! Very well explained thank you!

[@neilvandenheuvel4923]

Did you ever figure this out? I can't get mine to stay in either.

THANK YOU!! Made my first QuadraJet rebuild a breeze!

Excellent series, but noted the same as below, the hook for the needle valve is supposed to hook over back side of the float mount, not in the holes. Supposedly it can flood if the hook is put in the holes, maybe it causes the needle to hang up some how. Thanks a lot for putting this on you tube, it is a GREAT help! I had heard for year that the Q-Jet is complex to rebuild but I did not find that to be the case when I did mine on my '88 OMC 4.3 4bbl. The main tricks are being careful with re-assembling the air horn to the bowl keeping the metering rods in the right place. That and fishing the choke rod on the left side through (bright LED flashlight helps with lining the link up with the hole in the lower lever).

I bought a rebuilt Q-Jet from Rock Auto. Worked perfectly for a couple of weeks. Went to start the car one day and it did not want to light off. I pumped the throttle, etc. Finally got it to run, but the idle was terrible. To save a little time in trying to troubleshoot I just took the Q-Jet from one of my other cars, put it on, and everything was fine. That led me to believe that the problem was my rebuilt carb. Rather than go thru the hassle of returning the carb to Rock Auto I decided to open it up and see what I could find. Lo and behold that little clip that goes on the needle was not there. I looked for it in the float bowels. Nowhere to be found. I can only surmise that a "new guy" in the rebuild shop didn't pay attention to reassembly instructions. I had to buy a complete needle/seat since they just don't sell that clip by itself. I am putting the carb back together now. Having a little bit of trouble with a sort of spring clip that hangs on the accelerator pump arm and (I think) presses down on the idle vent when the throttle is opened. I'll figure it out. However, while putting the needle/seat in the carb I found several instructions that were quite clear in saying you don't put the clip in the holes on the float bracket. Live and learn. My vehicle is a 1967 Olds 442. Carb is a 4MV model.

[@crookedboot2727]

Some people say that you don't have to use the hook on the needle, that the needle will open anyways due to the gas pressure , thought's on that anyone?

[@dodeca328]

Good. Thanks for the video.
