Bill , I live in fort bend county too. You car does not need emissions testing no matter what plate you have on it. It is over 24 years old. Yes the gas could be flowing back from fuel pump. You can buy an external fuel filter with a check valve and see if that stops your problem.

Hello that is normal for most all chevys in 80's Crank for about a second or to, then stop pump accelerator several times hold to floor and start cranking again. it should crank they were bad about loosing prime in the 80's. worked for G M and they were bad about that sitting on the shipping lot for a few days when new. Hope that helps.

I also had that problem , I scrapped the smog junk & computer & installed an EB carb & int. manifold & vacuum dist , that helped but still had the problem so I rebuilt the charcoal can but still have gas fumes in garage but no leaks , part of the problem is Ethanal fuel , bad for all carbs , makes the needle valves stick open & gas runs into the engine when not running . I tried using Seafoam fuel treatment & Ethanol free fuel , helped for a while but doing it again , I also changed out all rubber fuel lines to ethanol proof fuel lines . I tried all these things now I'm trying ethanol free fuel & Seafoam together . stay tuned .
It seems to be working so far , I never had to crank the starter for more than 10 seconds about 3 times , as soon as the fuel pump filled up the float bowls it would start right up always after sitting for many weeks .now the fumes seem to be gone & it starts right up .

Having to crank a starter for 10 seconds is still not right ! Its better than cranking for 20 seconds but still not right !

As for my 2 cents, I've had starting issues like you have mentioned in earlier posts on most of the carb cars that I've owned after setting for a day or more. Crank a few times to get fuel into the carb and set the choke and fire up. Then again if it doesn't start the first time. The cars that I have owned with fuel injection fire up right now after setting the choke. What I did with some of the cars that I've owned, I would install an electric fuel pump by the gas tank and remove the stock pump. Turn the ignition key and listen for the electric pump to stop pumping, set the choke and fire right up every time. My opinion is that the fuel can evaporate in the carb from the heat of the motor and leak back down the fuel line over time. I have that issue with my El Camino now. Nature of the beast. I plan on installing an electric fuel pump some time down the road. One way to look at the cranking is that while cranking a cold motor, your oiling the engine before startup. Happy Thanksgiving to all.

First, I want to thank all you folks who recommended Mountain Man for a rebuilt carburetor.
I ordered one, put it on and only had to adjust the idle a tiny bit. And, it my Camino runs like a champ. I've even discovered a whole new passing gear with real gusto.
So, put me down as another El C owner who would recommend Mountain Man.

While on this Carb Discussion there were a couple of you friends that said you lived near me being in Rosenberg, Texas.
Do you have any interest in finding a central location and meeting up for lunch or dinner? I love a chance to visit with you and check out your Rides.

For those of you who said they also had a starting problem after their El C sat a while, I'd like to pass along a tip. This isn't original with me, but came from Mountain Man Fuel Systems. Without pumping the accelerator simply turn on the ignition and spin the engine for a few seconds, and immediately after that pump the accelerator 3-4 times. Then resume cranking. and for me the engine starts right up. I hope it works as well for you as it has for me.

OK, Guys & Gals, I could use a little guidance here:
I have a stock 305 V8 in my '86 El camino. If the car sets for over a day it is hard to start.it takes a lot of turning over to get it started.\

Two mechanics have told me the Rodchester carburetor is known to leak gas and leave the bowl dry. And, thus the long time turning over to get gas in the bowl to start the car.

So, I'm looking to replace the carb. Can someone advise on on what I should get to replace the original Rodchester? My Camino is registered as an Antique, so the car no longer has to pass inspection.

I have over 40 years repairing autos. VW to LandRover.
Most of them were GM vehicles.
When your engine needs to crank for a long time to start after it has sat overnight, the problem is most likely the fuel pump.
Yeah the fuel pump. Gasoline will leak out of the pump and there will be a little clean spot on the pump body as evidence of a leak.
When that happens it will also drain the carburetor of ALL fuel.
I have see that many many times over the years!
Test my idea.
After the engine has run for the day pull the air cleaner off, and insert a long toothpick in to the carb by the hold down post, in the center, by the choke plate.
Mark the toothpick were the toothpick sticks up of the bowl.
This will be when the toothpick sits in top of a the float.
Tomorrow check the tooth pick and see if it is lower in the bowl, past the line mark you have made yesterday.
Is it is lower the fuel pump has suck the fuel out of the bowl.

Keep the original Quadrajet carburetor they work great when tuned properly.
I have three El Caminos, two 1986 and one 1985.
All run great.

interesting, but where does the fuel leak to? into the oil pan or external to the engine block? I have a 86 Elkie with 305 experiencing this hard starting issue right now.

1) catches after 2-3 starts, runs a little and dies
2) starts immediately again and runs a little longer and dies
3) repeat start and runs a little looonger
4) after 3-5 times of step 3, it finally stays with a low idle. if I try to feather it, it dies
5) wash rinse repeat steps 2-3-4 above, eventually it stays running and even allows feathering to a little extent
6) finally it idles regular and eventually starts roaring like a v8 should when given the gas
7) all told takes about 5-10 minutes

also getting a run-rich smell and a "missing-putt" sound from the exhaust

Ray, it sounds like your choke is not working (especially if, once warmed up, it runs well.) You may also have fuel draining out of the carb (wells under the carb leaking into the intake or draining back toward the fuel pump). Drained/leaked fuel would make it crank longer before firing but the choke not actuating will cause the stumble, stall and repeat you’re getting.

I got a Rodchester carb from Mountain Man and it came with some starting instructions.
Without pumping the accelerator you spin the motor for 5 seconds or so, then pump the accelerator 3 - 4 time without trying to crank.. Then turn the ignition to crank.
That has worked great for me on my '86 Camino.
