Edelbrock 1405 carb running rich

I sent my buddy this image and circled the choke bracket and asked if he’s got it but he hasn’t responded yet, if he’s got it I won’t need yours but if he doesn’t I’ll buy yours as long as it’s cheaper than off the internet. So if there’s plenty of fuel flow to the carb, good spark at plugs, what’s the next step? Would that conclude it as carb problem? Not enough fuel? Still too much fuel? It ran fine started right up before I changed the jets/rods. Now it won’t start. Should I just change the jets and rods back and accept it running rich? It ran after I changed the jets I believe but ran terribly? I can’t remember I’m trying to juggle so much with this truck and trying to find the soonest warm day to rebuild my front end on my truck. Got new leaf springs and all steering parts. I’d love to have another truck to be able to drive while I work on my daily.

Its possible something got messed up when you had it apart and were changing things.

Would the step up springs make that big of a difference? I didn’t change them I just put back in the original. I believe they were orange, they were dirty from half way down. I assume fuel? I cleaned the carb a little it had mud in the bottom of the bowl on both sides and in the bottom of accelerator pump. So I cleaned all the dirt out. Are the springs that vital? I have a few other sets but they aren’t colored like real edelbrock ones. They’re just a set from eBay.

If it’s worth it I’ll rebuild this carb, the gasket holding the air horn? I dunno the top plate. It had a small bad spot in it but I just left it there just incase it didn’t run I didn’t spend a lot on a rebuild kit for a junk carb. It’s leaking fuel around the throttle linkage, is that flooding? Or is the carb junk. Float level too high? I didn’t mess with anything other than jets rods and cleaning the dirt as good as I could

Like right here says about fuel leaking around shaft, is that around the throttle linkage? So since I had the carb apart could I have maybe bent one of the floats? I never touched them but I did have the carb sitting upside down on that top plate so the floats were up in the air I tried not to touch them because I didn’t want to mess any of it up, but if this could be a possible carb problem I’ll yank the top plate back off again.

Oh I forgot to mention the distributor “tickled” me yesterday. Dad left the key on yesterday and when I was putting the distributor cap back on the post for #1 it sent a tingle all the way up my arm. So I know atleast #1 is getting spark at the distributor.

@Bextreme04 he said he thinks he ended up having to use that part, I may have to get in contact with you and arrange you sending me that bracket. Only other thing I can think of is I made it too lean. Should I go back to the original jets and rods and see if it runs? Since I know 100% the timing is right now? I’ll also check out the old spark plugs I took out and compare differences and gap the plugs to .40 since @AuroraGirl suggested .35 for LD and 45 for HD and I dunno what this truck is classified as. Hopefully making sure the spark plugs are all good and working and fuel flowing to the carb will elemental the distributor and fuel flow. I was reading last night some more about the hei distributors and read some stuff about the hei ignition module could go out and it will spark at the plug but it’s not a good enough spark to run, if it comes down to it I’ll replace the whole distributor. I don’t want to just repair this one since I didn’t do the original work I don’t know how half assed this engine is. To tell one thing there was orange gasket maker I assume is what it was, inside the distributor hole in the intake manifold. It made it a pain to pull the distributor the whole way out and drop it back in because it took up a good 20% of one side of the hole. So I’m going to assume atleast the intake manifold has been off before. I don’t feel like that much gasket maker is factory. I’m willing to try anything to get this engine running and save it, but after a certain point I feel it’s not gonna be worth it and I’ll just drop a good 350 with a q-jet in. I’ll change the carb, although I don’t know the vacuum routings for a holley nor a q-jet. I had to read the manual for this edelbrock to make sure I had the three vacuum ports hooked up right. I have probably 8 holley carbs and probably 15 q-jets, a few two barrels too but rather stay with a 4bbl. I’ll have to find numbers on all of them and run them online and try and figure which is best and best condition and probably redo all the gaskets and give it an over haul but if that’s what it takes and I know it’ll run then I’ll do whatever it takes. This cold weather isn’t helping my case. It ran rich so I leaned it and then the temperatures went from 50’s to 20’s and now it won’t start

Found the old spark plugs I pulled out,

they’re pretty black as well, but also a different model. R43TS, as @AuroraGirl mentioned about the ts, could these new spark plugs be not so good enough to run? Should I clean these older spark plugs and throw them in? Do the new ones not reach far enough into the cylinder to fire a good enough spark to run properly? If I need to clean these and put them back in I should re gap them? To? .45? Since they’re TS plugs?

 

[iamtherealJayy]

I don’t know if I already answered the question of whether or not fuel is squirting or not, yes fuel is squirting evenly on both sides. I’m going to go disconnect the fuel line and see if it’s flowing to carb fine and also test spark at the cylinder. I’m going to use a wire brush and clean the old spark plugs and try them.

 

[iamtherealJayy]

I currently have the top of the carb off, while taking the metering rods out I noticed they weren’t the same, I must’ve accidentally put a new one in one side and the original in other side. There’s fuel in both sides of the carb. The accelerator pump squirts fuel out the nozzles. Should I change the rods and jets back to original? Did I go too lean?

Make sure you have the float levels set right and that nothing is binding up or misaligned. I would stick with the new stuff, but makes sure they are matched side-to-side. Verify what is in there and where it puts you on the graph in those instructions. If it still doesn't start, you can go richer by just changing the rods back to the original without removing the top of the carb.

I changed the rods and jets back to original, still no start. It’s trying to, it just won’t kick off and run. There is still fuel leaking out the throttle shaft linkage. And the drivers side float was dry? I’m not sure why they were both at same height and they both were full of fuel. Why was one float dry and one had fuel on it?
I’m going to swap the old plugs in since I cleaned them up and see what happens

 

[iamtherealJayy]

Can confirm it was quite flooded… a couple spark plugs had gasoline dripping off of them. I put the cleaned R43TS plugs back in. I’m going to wait a few minutes before trying to start it.

 

[iamtherealJayy]

Truck fired right up with these other plugs. It keeps shooting air back out of the carb tho. Is that timing too advanced? It’s making progress now. It fired right off with no choke. I’m going to ziptie choke barely open and try again.

that carb sounds like it needs a rebuild or just get another carb , do u know anyone that would let u try out there carb just to get it running ?
