Pretty new to this forum and have been reading a ton and it’s really awesome. Just a quick intro I guess I’m from Canada and I bought myself an 83 C10 last June. It was drivin and stuff but everything was covered in gunk so I took it apart and drive it down to the truck wash. Replaced every single gasket and some new parts.
Being less than an amateur mechanic who had no business taking apart an engine with just a manual I decided not to mess around with the Carb and just sent it off to a “carb” shop.
Now I have trouble starting it and keeping it running. I’ve “diagnosed” everything as best as possible and it starts?
I’m thinking it’s the choke or something however I don’t know enough about carburetors and stuff to know what’s specifically wrong and what to adjust.
When I start it I have to crank it for a while. If I prop the choke open it’ll give immediately and I’ll remove the screw driver. I fiddled around with the idle speed to raise it and when the engine warmed up like three or four minutes the choke started to close and then the engine died. Also same thing happened cause I went in the cab to gas it and it died when I stepped on the accelerator. Any help would be appreciated . Still in the process of obtaining a tach and vacuum reader.

What carb shop did you take it to? Looks like they sprayed it off with carburetor cleaner. A proper rebuild should be tanked and spotless. What's up with that clear hose?Just a shop in my local area. They have a “carb” guy there. First time going it was about 300 dollars. Invoice says I got charged for a rebuild kit.
The clear line was my fault. Didn’t know the trick for removing the meta line and began unscrewing the fuel filter nut and wrenched the line apart. It’s flushed and I also used to to verify fuel was getting pumped. Will get a metal line soon hopefully

There are TYGON fuel lines, which are clear-ish. But that may be a little $$. And I don't think they'll like the heat underneath the hood.
Also be careful of running the hose/line near the heater core lines, don't want the heat up the fuel too much.

I'd reach out to the shop.
Is this your first vehicle with a carburetor?
Post by: THE-JOSHTER on March 19, 2021, 06:09:09 PM
So I'm assuming that YOU took the carburetor off and delivered to the shop for the rebuild? That's quite a bit of money even in CAD for a bench rebuild especially one that looks like that afterwards.That’s what I did. Took it in a box. Honestly not sure what to call them out on or get back at this point.

And yes this is my first vehicle with a carb. I am trying to learn more and research

As it runs the choke starts to open.
The shop should have dipped the carburetor metal parts in a container of carb cleaner. The top looks like it still has a lot of dirt still on it.
If you call them and explain the problems, they may let you borrow a tach and vacuum gage in order to potentially get it running enough to bring it to them to check their work. I'd do as VileZambonie suggested and make sure you don't have any vacuum hoses disconnected or something else leaking vacuum which will cause an issue.

'Josh'? Welcome from SoCal San Diego. And welcome to the world of Square Bodies! You are in for an adventure if you have the ***** to stick it out. There will be a lot of people willing to help you out, but know one thing, you need to be specific in what you ask. If you don't understand it, that's OK. Look at this as a team of enthusiasts with the same goal.
We all started somewhere... Just be patient with yourself as you grow in understanding. One day you may be able to help a fellow SB brother/sister with a problem.
Regarding the 'carb rebuild', I agree with the foregoing remarks. You need to get that resolved first. Either refund, or some other resolution. Future mechanical work that is not as cerebral, brakes pads or shoes, radiator flush, Tire Pressure...?
The first question on 'it was drivin'. Was it driving ok prior to your wash down?
Second, your description of the choke operation is confusing. Can you video tape the " If I prop the choke open it’ll give immediately and I’ll remove the screw driver. I fiddled around with the idle speed to raise it and when the engine warmed up like three or four minutes the choke started to close and then the engine died."
Along with the earlier comments, your choke may be the problem but it's hard to tell without specific information or video of what is happening. Too much conflicting info at this time.
I look forward to offering assistance. I'm sure I speak for others as well.

I just didn't want to make you feel unwelcome since the typed word is hard to convey certain things sometimes.

Hopefully you did not take offense at anything I said. Any grief I was giving you was in jest. Also, the comment about the expensiveness of metal lines was due to the fact that Canada isn't that far away yet some of the pricing is due to high tariffs, etc. Also, it wouldn't seem to affect your problem if you had rubber lines, in fact a lot of us have rubber fuel lines.Oh no for sure mate. I wouldn’t crack that easily it’s all fine. I had the rubber hose on initial but it’s a tight bend at that junction so the thin line just gives a little easier. I do have the metal line on order from and it’s not that bad. I’m currently trying to source a double d bit to adjust my carb but no luck. I did some reading and I figure the mixture could be the problem but until I try and set it I won’t know.

Carb shop wont budge on a refund... dunno possible its a dead end
I cant figure out how to load a video up on this site so i may have to try it on a computer later...
Ive gotten it to where it starts on a few cranks now. I got my hands on a carb adjustment tool and seated the screws and then turned them 1 1/2 turns out. My start procedure is that i floor the gas pedal and then crank it. however after it starts and i remove my foot it stalls immediately. I played around with the idle screw but that didnt do much and once the engine heated up it wouldnt start again (unless i propped the choke open with a screwdriver) and i could see heavy vapor coming out the top of the carb...
Not sure what that means. Still waiting on my metal line to be shipped in. Ill try and get a video on tomorrow AM

Got a video! hope the link works..
Not sure if this is what yall need to see as i propped my phone up and ended when it fell. let me know. Followed the proper starting procedure and still no start. can verify there is fuel, and also on the note of DanMcG the spark plugs are new and i did verify the spark by pulling git out and grounding against the engine. also I had the idle screw tightened right up initially but I loosened it out three turns as a start.

If you have a helper, have them crank the engine as you advance and retard the dist, the nipple on the vacuum advance point the direction to advance the timing. Once you get it started, check the timing with a light and set.

With the engine cold after sitting overnight, remove the air cleaner. With the keys in your pocket and the engine OFF, prop and hold the choke plate open so that it is completely vertical. Using a bright flashlight, peer down the throat of the carburetor and operate the throttle by hand to quickly open it all the way two times. Did you see two well-defined streams of fuel squirting into the center of the throttle bores both times that you opened the throttle?
Yep. Both times there were two streams. Engine sat overnight and just went out and checked.

Actually, loosen the dist clamp where you can turn the dist with effort.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
She runs!!! and drives!!!! I drove her out of my yard!!!!!!!!
Have yet to get a timing light to get it on spot but moving the distributor worked!!!!! I moved it counterclockwise. its far to the right so i may set zero and pull the distributor to get it closer but thank you all so much!!!!!!

Your video gave the clue, she was trying but wasn't getting enough "Fire Scarecrow"!!!

Advance your timing a degree or two. Thank Carmen77 for the idea that came from her dad!

Thank you Johnny for the credit
Yes, I had this exact issue and my dad was able to guide me through the timing issue through the phone. It was like having a new truck once I was able to get the timing right.
