Thanks for this and all your other videos! I just changed the plugs on mine and found that the carburetor seems to be rich as they're all quite black. How do I lean it out a bit?

@ELDESTBuilds 3 жыл бұрын

Too many variables, how old are the plugs? Are they the right heat range? How many mile on the plugs? How many miles on the motor? Is it smogged? See where I'm going here? Good work on changing the plugs, I'd go on with the rest of a tune up before I considered leaning out a carb. Adjust the settings on the carb like in the video to best tune the car at idle. Any leaning out requires cracking the carb open and jet changes. Probably not necessary unless you made adjustments to the rotating parts.

Thank you for posting all these videos. Working on a carb upgrade abs manifold for a 1980. I can’t get the throttle rod bent in such a way I get the secondary to fully open. I got two spacer the 12mm and a 2 mm. What spacer should I use. On your install you used the 12mm. Also did you altered the length of the rod? I am cutting them as the oem 9”. Then threading them at 10/32. I am on my 5th one and got a little frustrated. Any insight in to the length, bent angle , length of first run after initial bend starting at carb side. Should I got longer or shorter? The problem is at the high point of the rotation and the angle the throttle is being pulled. Total throttle travel is 1”. I can get to 3/4” and the binding starts. Thank you for all that you do. Especially the Velcro trick and sound and heat Barrier for interior. Saved me a lot of time. Also the fact that you talk on the important teaching moments abs findings.

@ELDESTBuilds 2 жыл бұрын

I couldn't get wide open with the spacer from the kit, maybe 2x on the 12 spacers to get enough height to get full open on the throttle. I built a spacer out of the old carb which took it back up to the original height. Had to make a few bends to the rod to get it right. Glad the videos are helping out with your build. Check out the carb riser video for some more rod bends. Oh I got some new lowering springs in the beginning it goes to carb riser after that. kzfaq.info/get/bejne/Y5aDaMyIptGnpnU.html

@@ELDESTBuilds Thank you for your help, I really appreciate it. I used 2 12mm spacers including the gaskets , well 3 of them, that did the trick. The throttle force is now linear. I will have a spacer machines out of aluminum but the setup up now will work. Can’t thank you enough. Something else on your install video, the line to the brake booster. It seems you showed the fitting for the hose on the intake manifold that came from the gulped valve. The line to the brake booster is smaller. I ended up using the brass L fitting from the old manifold, same thread size. Was there a benefit on going to a larger diameter hose? I do not want to bother you with silly questions. I just think you did an excellent job and want to understand if some of the things where to improve the performance, especially the brakes. I will make sure to ask on the correct video next time. It is amazing how much time Anyone is able to save because of your detailed videos. Really appreciate you taking the time for all the fine details. This was not a first choice car, neighborhood had it sitting in garage for a long time. Told me he had no time for it. Prior owners did a lot of little things I am untangling. Have a great evening and once again thank you for your help.

@ELDESTBuilds 8 ай бұрын

Check intake side nuts and bolts for torque. Those carb nuts will sometimes rattle out of spec. Check vacuum lines for leaks. Check fuel delivery to the carb. Then set the idle screw to the rpm that keeps the car running. Now you can check the electric side, timing and advance and such.

Wha does it mean when my idle mix screw doesn’t have any response. IE idle mixture screw is seated and it doesnt want to die. If backed up no change in rpm.

@ELDESTBuilds Жыл бұрын

Two things are most likely, first is the throttle screw is too much, engine rpms too high and idle screw is bypassed by the butterflys. Second is the port is blocked and needs a cleaning. Idle mix is only for low rpms, less than 1k+/- then the butterflys open and it gets the juice from the jets.

Those do not effect lean/rich. They just make it idle right. Set timing to 10° BTDC, make sure all the carb nuts are tight and take it on a high speed run, like the cops are chasing you. Then pull the plugs and see. Smelling gas doesn't mean running rich.

That was fairly simple. Now, have you aver adjusted the choke on a Weber carb with the thermo choke? instead of the electric unit it uses engine coolant to warm up the spring to open choke. My friend has 2 1976 Lancia Scorpions with the thermostatic choke on the Weber carbs and neither choke is closing . Got one of the 2 cars to run yesterday . Swapped carb from one to the other to get it running but the choke is not working properly . it stays open all the time. 1.8 L engines DOHC.

@ELDESTBuilds 2 жыл бұрын

All is not lost. There is an exploded diagram of the carb assembly that shows the proper assembly of the choke mechanism. Also, it is possible to remove all the choke assembly and run without but requires disassembly of the carb to remove the rod and flap. Then you would just use the give it two or three pumps and start it.

I just purchased a Weber carb for 1971 fiat 124. I’m missing something because it’s my understanding that the electric choke opens the butterflies as it warms up, when you shut down the vehicle and the car cools, the butterflies should slowly close. So the car sits overnight, I turn key on but not over, tap on the accelerator once and car should start right up with the choke engaged. Correct? I’m manually having to open the filter and wiggle the butterflies shut in order to start.
