Any chance of going to a yard and snagging that melted connector off of a similar car? Then it could be wired back in, and give you back the electric choke, or whatever it's for.


I.. am either going to take it for a shop to see if some electrical mastery can be done, as i think i see wher eit attaches and i have to wonderr how it will run with that wire attached

My car "Seems ok" and i have the vacuum OF THE EXHAUST patched up for now, with dimes that cant moved sandwiched in Ultra-copper RTV as suggested bya Third Gen board. Should hold, i . notice no major vacuum leak (which it had before i impeded airflows to the emissions air tube) and.. well, good start from there.

Guess what Lost all the coolant today. I confirmed a leak in the "lower hose" a fw days ago.. today i took it out for ~20 minutes, came back the leak in the hose was hissing liek a tea kettle!

I popped off the radiator cap, it was sounding exactly like a tea kettle for about three minutes, all coolant was gone.. good thing the leak in the lower hose was there, or it would have popped out my radiator, or engine.
laugh.gif
So i have the lower hose off the car, and i poured water (hot on cooling down engine, and through radiator, for tem differences, this is a cast-iron head like my first car IIRC so i dont fear cracking anything, and i made sure it was hot too) so its nice and flushed.. sitting with no coolant and lower hose OFF (it has a spring in it too, and gave the oil a workout since it catches heat the cooling system cant carry away) .. waiting for new hose.

Im more or less back to where i was, but the vacuum is making the car "Driveable." My blocked-off connections of exhaust fumes (thanks 440Magnum) make the car a joy to drive : I otice little to no "hesitation" and ive tried to recreate the hesitation.. ive yet to pin-point it, ive ruled out Head Gasket, even the "statup smoke" cant decide if it wants to or not. Strange!

But i still have strong-runnign car, with good trans.. drove a few 30-second to 2 minute trips with no coolant to move the car, it did well, engine heated up nowow its cooling back down, block and radiator are flushed with water via upper hose, i cant take off the thermostat because AC hoses block it in so ill have to leave that.

but for now, im awaiting a hose, since local parts stores DO NOT have it, and i DO NOT have the $10-$16 and then $24 for coolant (!) to patch it up and go. maybe sealer, as preventative maintenance, as Scotty Kilmer on Youtube say s(SteelSeal, he puts it in when he changes his coolant, as i just did, boiling it out through a leak in a lower hose, so i changed it too.)
laugh.gif


If i had burnt up the engine, id konow it from how it ran. Ive had car soverheat' before. Mine didnt do that, just hissed liek tea kettle, then it cooled, then i drove it 1-2 minutes w no coolant, so its void of colant, i flushed it w matching temperature water and radiator too, now its good and cold, RTV setting, and part X is yet to come.

10W-30 motor oil, if not 10W-40
Extended Life coolant, maybe with "Steel eSeal" as preventative maintenance
and Mos2 in the oil, myabe "restore" or a "microlubricant"

and let it run, run, run!

Its got good engine, and i may have come CLOSE to damaging it today, but im confident i did not. Especially since im back to where i started, choke stays open all the time, its fuelish, sure, but now it runs good due to vacuum fixed.. coolant change, it came out, again.

Thats the update for now

Noticed it today, after i lost all my coolant.yes thats right the hose in the lower radiator save my engine's tooku, since the steam pressure shot out of it and not a radiator. (Had leak in lower hose. Finally took it off today.)

Seems i need to change my oil and use 10W-40, since my carb has gas going -somewhere.-

Please tell me more about the "IMG" and i WILL cal a mechanic for that one, thank you (using gas? .. Intake Manifold gone? maybe my engine did this and i have no cloe what it is.)

reading th eposts here, i thank you all!

PS: My car is fine, its sitting, waiting for ME to put on a new hose affter finding the hose, and refillign with coolant, and maybe a Blue Devil/Steel Seal sealer, as Preventative Maintenanc,e since it was recommended to "ptu it in with every antifreeze change"especially since i cut it so close today. Yeah. too close for comfort, but i saw the hissing, saw it was from the ose and not somewhere else, let it cool, and engine showed no signs of "running hot ditress." NONE. Starts back up strong too, even after that (an horu late ror so.)
 
IMG is probably the Intake Manifold Gasket.

Stop putting miracle products (like steel seal) in your car!!

You don't need fuel additives.
You don't need oil additives.
You don't need stuff for flat tappets or to enhance SM/SN oils.
You don't need antifreeze additives.
You don't need to run the thing for hours in your driveway wasting gas if you have no money to fix it.
You need the cheapest certified store brand fluids you can come by in the right places.
You need tinkering here and there on hard parts to get the thing reliable.
You might need stuff outside your skillset.
You can run around with water in the rad for a week until you can afford coolant. It may even flush out some crud.
 
When I was 18, I learned to fix and rebuild carburators long before I learned how to work on brakes. Carburators seemed to mystify everyone else.

It was easy. I simply took the carburator apart, cleaned everything, then put it back together with new parts from a rebuild kit and adjusted the carburtator to factory specs. As long as no mistakes were made, each job was successful.

You mentioned some roughness at idle. Does the carburator have a lot of miles? If so, the throttle plate bushing is likely worn, leaking vacuum. You'll never get that fixed. Though it'll run fine on the road, you'll never have a good idle. Only a new carburator can fix that.

Frankly, if you don't have the $10 to $20 for coolant, I don't think you can afford to fix the car to decent running condition.

I just took the thermostat out and thermostat housing off, stat was BROKEN! Also, its orange-like in the "pool' under the housing.. debating which degree to put back in. OEM is 195 or so, its HOT out here though! Hmm.

As to the carb, i also verified that when i close the Choke (it doesnt operate it just hangs open, idk why.. there is a latch i can put in it FORCES it to STAY closed almost ALL the time, i can take a picture for you if you would like) it .. wants to die.... when the choke is closed. When its warmed up, it just starts right up though.. i used ot have tO FLOOR the gas to get it to do that, and i wasted $80 on a tow when i SWORE it wouldnt start back up. BBoy, did i feel foolish on that one.

I wonder how much i can pay a mobile mechanic that KNOWS ABOUT CARS to spend a day on my carb. And rebuild kits are "ok"?

I have 1) lower hose off
2) Thermostat housing off, stat out.. need NEW both of these (my old hose has a Spring! ? ? ? Do i NEED that spring ?)
.. and3) starting/driving it for "5 minutes" 2 no coolant, the water is runnig clear from the block AND the radiator. Just needs reconnected, good hi-mi oil im debating 10W-30 and 10W-40 (or thicker?) and i should be ok.

Bushing... hmm, yeah i sprayed it a LOT w running w car/chke cleaner, it looks clean down the throats but i cant see under it. Darn.

.. tips? thanks Kestas!
 
How about taking all this energy you are using to find hack fixes for your car, and use it to find a job so you have money to fix your car properly?

Just an idea.
 
This thread does make me cringe a bit as I feel your pain.
I had an 81 Omega with the 2.8L and vacuum spagetti carb and also ran into driveability problems. My "mechanic" at the time somehow diagnosed a leaking intake manifold which had warped, so he got it squared up which helped but any actual carb work was out of their league. I was and am not a mechanic but I did clean the carb and tried plugging various vacuum lines but with no success.
It ran mostly OK so I sold the car certified for a decent sum to somebody who wasn't afraid of the carb issues.
My secondary plan was to go to a local garage with an older mechanic who specialized in chevys. A tech who is younger than your carb probably isn't going to do well trouble shooting it...
My other plan was to go to a "off-road" carb with a manual choke and just run vacuum to the brake booster and rotor, but new carbs are expensive, and my wife was not down with putting money into the car.

Maybe this is would help you?

Indylan, thanks. Its starting to turn into "driveability issue" slowly but surely..

My backup plan is to buy this $400 HOLLEY carb, for my engine.

http://paceperformance.com/i-6108141-remanufactured-carburetor-r-2-holley-reman-64-70125.html

Maye buying that, taking it to a shop, say"Make it run smooth and do the Intake Manifold gasket, change the fuel filter, time it with a new coil and distributor and new EGR valve, water pump, timing belt, the works" and biting the bill of ~$1000 will be it?

Or, maybe just call up amobile guy and get the stuff done one by one..

How do i diagnose "runs all messed up and sometimes runs fine" ?
 
It's hard to say what to do, maybe weigh what you could sell if for plus your estimated repairs and see what you can get that has FI and is good on gas?
 
UPDATE

in other news. i replaced my BROKEN thermostat with a Stant 195 degree unit. Made agasket with the Permatex Ultra Copper. Car runs -really well,- folks. That old BROKEN (!) Stat is out.. and there were no vacuum leaks..
no "Stalls"...
No "overheats"...
It ran quite well.
All i did was put a Stat in, and refill with Water and the last of a flush i had. Im pleasantly surprised, actually

Sometimes the little things can make a big difference. When one thing isn't doing quite what it should, other stuff can react strangely, particularly when dealing with complex carbs like yours.
