Okey doke it was broken this morning but seems to have cleared its thoat for now. huzzah?

 

It started working correctly shortly after I made a tin foil gasket to try and get a better seal for my temporary solution here.

i know my craftsmanship is shit.

 

Not sure if its a coincidence or not.

All right update it's still broken, perhaps even more broken. I took the carburetor apart for the fourth time and cleaned out the fuel lines for the seond time and still didn't see anything.

I thought it might have something to do with the ignition but besides the points moving or the plugs getting fouled I can't think of anything that would cause it to break so spontaneously, and both those things are fine.

 

Any other ideas about what could be happening? I took a video of it trying to start, although the real problem is what it does when its running, not as easy to get a video of that though.

 

You can hear it firing fine while the starter is turning it, but its not enough to keep the engine spinning on its own..

So what is this? Has it anything to do with the intake?

it comes out of the exhaust manifold it was some emission control thing. car ran fine without it covered, it just lets fumes in through the firewall.

but yeah it shoots air out. dirty ass air.

Um, alright dude.....I am the self proclaimed ratsun redneck fixer from New Mexico and your edging in on my turf. :thumbup:

 

Now, take off the electric plate cover, take a pic of what it looks like without it and let me see if I got something I can send you or maybe figure out what is supposed to be there, cuz brother, that ain't OEM.

Probably the exhaust supply for the EGR but is the intake sealed?

A primary idle jet looks much like a secondary idle jet, except for the location of the fuel inlets on a DGV, did you put them in their original locations?

 

In your video, I don't see a cable for the cold start choke attached.  That upper butterfly being closed will allow the motor turn-over but soon after, it needs to be cracked open a bit.    Generally, carburetor fed engines don't benefit from pumping gas beyond setting the fast cam (pressing once when cold) all else is just fouling spark plugs.

 

A carburetor shouldn't need to be cleaned if the problem that you are experiencing is a lack of vacuum.  Notice how opening the throttle made the motor die in your video.

There needs to be a plug for the exhaust manifold side of the EGR and one for the intake manifold side as well.  Typically an EGR valve works as a plug because the spring forces it to stay in the closed position.

Better to have left the EGR on so there's no vacuum leak.

Alright. I do believe my explanation still makes sense. You really should try.

Your carb is tuned to act like it has a choke, when there is no choke. That's why it starts without choke, then dies 20 seconds later. Re-tune your carb now that choke is installed. It wants you to release the choke to run smooth after 20 seconds or so, but you can't, because it is already released. AKA, you are rich, very rich. It'll start, but once warm it needs the air that it can't get because it is not tuned. Find a manual choke tuning guide and go through it.

That's my guess.

Also, that single gang cover is no longer to code. You can't modify a UL product. Better stay clear of electrical inspectors.

I've went trough the Weber tuning guide in the past and I got it running all right. I think the spark is too weak right now to get it tuned perfectly.

 

I looked at the choke before because I thought it was just a problem with starting, but the real spot of bother is when it is running. I could be at full chat and if I let off the throttle for a second without putting it in neutral the engine will shoot fuel into the carb and detonate it and the engine dies and I sit on the side of the road trying to restart it for 10 minutes and everyones watching me because they think I've been firing off a gun. When the choke is on it won't try to start at all, it will just revolve like the dizzy's unplugged.

 

The real reason I don't think it's a tuning problem is that it was running for about a month while I tried to fine tune it. It would always be better or worse than the day before but it was always reliable until one night I tried to start it and it wouldn't go. I hadn't done even any minor tuning since the day before. The tunings pretty rough right now anyway because I keep taking apart the carb and I can't tune it when I get it back on because it won't run. I just know where the screw was when it was running.

 

And being an electricians apprentice staying clear of inspectors is a good portion of my job hah.

I can put the EGR back on for sure. I don't know where the intake side is but I've got all the other holes plugged well.

Yup I got them in the right places. I didn't know they were idle jets though.

 

I stopped connecting the choke because I am taking the carb off so often, and it won't start with the choke on. It definitely would before, I don't know whats up with it now. It would take a half second with the choke and like 2 seconds without.

 

I will put the EGR back on tomorow and plug up the little hose coming out of it, that is really the only vacuum leak I can imagine I had the shop seal the rest of it up with some nice looking plugs.

Fuel tank vent. Did you fuck with your fuel tank, lines, or return? If your tank can't vent, your pump can't deliver.
