I am appreciating this video. I did the quadrajet on my '75 Eldorado maybe 15 years ago. I was never sure what to really do with those well plugs. I had the overnight leakdown problem that persisted when I was done. Otherwise my overhaul seemed to work well. Next time I'll try the throttle shaft repair, which I had heard of as well, but did not attempt. You made it look pretty simple to do.
If you can take a Qjet apart, the bushing install is quite easy using the Cliff Ruggles kit. They also sell a plug kit which requires you to drill out the plugs and then screw in their plugs. Lastly you would put MarineTex epoxy on it from their kit. I decided to go the cheaper route and try the WaterWeld epoxy. If it leaks, I'll remove the carb again and drill out the plugs. We'll see.
Enjoyed the video. As an option, you don't have to remove the secondary plates or shaft. You can remove the linkage on the driver side of the secondary shaft, and leave the secondary shaft and plates in place. Then you can disconnect the secondary linkage from the primary linkage, and pull out the primary shaft. Removing the secondary linkage is takes a bit of figuring out, so pay attention to the dissassembly, even taking pics while doing it, so you can put it back like it was. Here are instructioins from the book "rochester carburetors" by Doug Roe: "first....pry end of inner spring off its ledge, then catch it with finger, and allow it to unwind (it only unwinds one full turn. that's how you'll rewind it when reinstalling). Next, release tension on outer spring by removing the straight end of the spring from its tang with pliers. Hold secondaries closed while rotating lever clockwise to let the spring clear its slot in the shaft end."
Has your JB Weld lasted over the last 2 years. Everything I have researched says it just doesn't last even a year. People recommend Marine-Tex but say it isn't a permanent solution either. Just curious, I'm fixing my tonight.
So far so good. The Marine Tex is the best stuff to use. I have used it in the past for this job but I did not feel like ordering it and waiting a week. LOL..... you can't get it anywhere around here locally that I know of. I used the water-weld stuff that is made to be used in a gasoline environment. i don't think conventional JB Weld can stand up. I used marine tex to rebuild a broken plastic front cap on a tractor. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BP8fqawbv_0.html
I have been subscribed for some time now but I just turned the bell on. You got me hooked on this carb so I want to see it finished as soon as you get the parts. How's the 300sd running?
Doing well but the it is now clear that the engine dampening shocks have to be replaced. The whole car rocks gently from side to side with each revolution of the engine. Engine doesn't miss a beat but I think that many people often confuse this oscillation with and engine problem. It will drive you bonkers, as it has me. Engine mounts will get replaced as well. Soon.
@@ImpalamansGarage hi. I replaced the shock on my 300d and it made no difference on the engine's rocking. Probably should have replaced the mounts. The mounts on my e320 are hydraulic and when they go bad the engine vibrates like hell. I replaced them and now it runs smooth as silk. Have a great weekend!
@@ImpalamansGarage Ok thanks. I was given this carb for free. Came off a Cadillac 472. I’m contemplating on rebuilding it or just selling as is. Not sure if it will even sell
Going on memory now but I believe I had a hard time finding what I needed for this older carb. I had wanted to find as many made in USA parts as I could.
