Long Sitting Engine test

Hi everyone, first time posting, long time reader. I've got a 69 with a SB 350 and it hasn't run for about 7 years but when it did, it ran great. So here's my scenario. I've replaced the water pump, alt, Harmonic balancer, carb, wiring harnesses in engine bay, added an MSD ignition box, Power steering pump and all hoses, wires, fluids etc. Only thing I didn't pull and replace off the engine is the distributor but did swap out all the wires , rotor and cap. I can hand crank the engine so it's not seized. I've also had Marvels mystery oil sitting in the cylinders for a week and will replace the plugs as well. All looks good for restart but the fuel lines and gas tank. What I'd like to do is try starting it by just filling the fuel bowls and not connect the fuel lines for fear of getting bad gas into the system and Carb. It's a double pumper 650 Mech choke. Does anyone think this is harmful to the engine or dangerous? Is there a safe and easy way to feed gas without the fuel pump? I'm worried using a container might be dangerous due to not being grounded. Am I wrong? Also, if it's OK to fire, approx how long will it run at idle before the bowls go dry? Please don't tell me to do it right and "just" replace the tank and fuel lines. I'm on a fixed budget, and most of all, with a family I have VERY limited time to work on the car which is how I got in this pickle to begin with! So to stay motivated, here the rumble and test the ignition system along with everything else, I'd like to fire it up even if it's for 2 minutes at a time and go forward from there. Sorry for the long post, any help is appreciated. Thanks!!!!!!!

Re: Long Sitting Engine test

Funny, last weekend I fired a SCB in a '64 chevy II that sat for 7 years. 7 years isn't that long. You've already wasted more time and money than needed. Top off the tank with fresh gas. Pull the coil wire. Crank it till to you see oil pressure. Put the coil wire back on. Pure some gas down the carb and run it.

Re: Long Sitting Engine test

If ethanol was in the carb and sat, it attracts and contains water, which corrodes the carb. Shoot some B12 down the vent tubes and see if the A-pump squirters start to work after a bit. If not, rebuild the carb.
Pull the fuel line to the pump off, feed it from a plastic gas can and some brake line. The carb is primed from the B12, which also works as starting fluid shot down the carb throat.
Not sure what a ground has to do with this but I'm ignorant...
How much gas is in the tank. You can siphon some out by sticking a 6' or so hose in the tank all the way, plugging the end, and pulling it out lower. No need to suck when siphoning.
Then put some good gas in. Priming the carb and using ether or B12 will help with quicker start.

Re: Long Sitting Engine test

I would disconnect the fuel line at the fuel pump and the sending unit, drop the tank, it only takes 2 bolts, unhook the electrical connection and set it on the floor. I have a hoist and found it easier to lay on the ground. I pulled it and put a new one in by myself, piece of cake. Remove the sending unit and check out what the sock looks like and clean it. You can now look into the tank to see what you have. If nothing else rinse it out and get the junk out. Blow out the fuel line with an air hose, see what you get, you could use carb cleaner first followed by air. Put the tank back in, fill it with 5 gallons of fuel so that you can verify the gas gauge so you know where you are at.

The last thing you want is to fill the new carb full of junk. Did you change the oil?

Re: Long Sitting Engine test

I had my car sitting in the garage since sept. of 09. just started it up this weekend. all I did was replace the gas, it cranked for a minute until the gas flowed to the carb and it started right up. The only problem I had was my Gen light stayed on until I taped on the voltage regulator, all good now

Yep, no need to do any prep. Hop in, and crank it.
I'm sure the battery has a charge.

Re: Long Sitting Engine test

Are you only worried about the gas tank? Is your fuel pump good? I ran my engine from a gas can by running a 4' hose from the can to the fuel pump and started the engine. Put a new filter between the pump and carb. I did it that way till I got around to dropping the tank and flushing out the varnish in there. Then I used an electrick fuel pump to flush the lines from the tank to the engine.

Oil has been changed with the "all fluids". But you're right. I forgot this is the internet and didn't specify that he needs a battery to start his car.
Good luck with the project. Don't forget to replace the oil pump. They go bad if they sit too long.

Re: Long Sitting Engine test

Thanks, guys for all the replies. Let me add some info. Yes, I know I need a battery, lol. The carb has been rebuilt already. It's a Mechanical fuel pump with new hoses and filter to carb. Tank and line to fuel pump have not been drained yet. My concern from what I've been reading online, (Too much info is as bad as too little) , is that the gas is fouled in the tank and line to the pump and that I will screw up the carb if it gets in there. There may be rust as well since there's not much gas in there. Again, this is what I've been reading. So I thought to eliminate that possibility I'd go with an external small container or just putting gas in the bowls to get a minute of run time. Then if it's running I can deal with possibly replacing the tank all together and line. Oh and I didn't mention the trunk pan is bad in places. I just keep peeling back that onion you know? So to stay motivated I need to hear it run!!!!! As for the ground question, static sparks etc was my concern. Grasping at straws on that one but better safe than sorry. I know of someone who's garage burned down because he had central vacuuming with pvc piping running thoughout. You are supposed to ground it every few feet which he didn't know. well, he vacuumed up saw dust and with all that material swirling around it creates static and boom, next thing you know the fire department is pulling up. Just thought I'd ask..........

Re: Long Sitting Engine test

Use a can (container) of gas from the line to pump and get it started. The bowls will not be enough to actually get it to idle for very long. That was your initial question. It would appear that you have addressed everything else except clearing tank and line to pump. You should be good to go. Enjoy.

Re: Long Sitting Engine test

Notatoy, thanks. So obvious I didn't even think of it. Just run a hose from say a gallon container to the pump right? "What's obvious to some is invisible to others." (I just made that up).
