Flooding and out of ideas
Hi guys. Hopefully somebody here know some tricks form me to get this car going. Apparently it was running about a month ago. I bought it as a project car to fix up as it was in good shape other than being badly flooded. It's 12A engine installed in a second gen car. I have another second gen with blown engine that I am pillaging for parts. Here is what I've done so far to try to start her.
- Installed a fuel cut-off switch
- Pulled and dried the plugs many times, turning the engine over with out the plugs or spark to blow the crap out of the engine.
- Engine seems strong, turns over nice, has 3 even pulses form both rotors.
- Swapped the leading coil pack an wires.
- Tried second gen spark plugs, as well as the originals.
- Rebuilt the carb
But she keeps flooding. The odd time she coughs, but not enough to catch and keep running.

Morning,
One thing that I have been running into, as well with my FB, is it flooding out as well, but from doing numerous searches online, I have narrowed it down to 2 things, the float bowl vent solonoid, and the floats and seats.
if there is no power getting to the float bowl vent solonoid, then it will keep the float bowls sealed, causing the problem at hand, due to the extra pressure put on the fuel in the carb bowls, causing it to seep out when the key is off and flooding the engine.
what you can do:
1st. get a pair of vice grips. and pinch off the fuel line towards the firewall of the car.
2nd. clean and dry off the plugs, and put a couple cap fulls of engine oil down both primary carb barrels, and turn the engine over with the plugs out, to circulate the oil.
3rd. reinstall the plugs, keep the fuel line sealed off, and crank the engine over while holding the throttle to the floor.
see if that will allow it to start and run, I know because I'm having the same prob's with mine, and I beleive that mine is due to that damn solonoid vent valve.

Thanks for th info guys, here is a little more info. I have a stock 2nd gen fuel tank and pump. Not sure if it has a regulator. What would I look for, and if I don't have one, what do I need? Apparently it was running fine a month ago, so I would assume that it would have flooded from the day the 12A was put in if the fuel pump was going too hard for the engine. It has a 2nd gen automatic tranny hooked up to the first gen 12A, so I can't pull start it. 2nd gen ignition coils as well. I do have a manual tranny on my other 2nd parts car thou. I was thinking of swapping the tranny just out of frustration but would rather get it started without going to that extreme if possible. If I end up doing the swap is it as simple as pulling out the automatic and putting in the manual trnasmission and clutch peddal? Or is there more to it than that? I am recharging the battery for another go at it. Maybe I'll try a little oil in the chambers to help the seals expand this time.

still, block the fuel off from getting into the carb, and try that, see if it will start and stay running with the fuel that is already in the carb.

I have a fuel cutoff switch installed. This turns off the pump with the flick of a switch. It is still flooding even if it is on for a little while as I try to start it. It is close. It seems to want to start after I pull the plugs and turn it over to blow the excess fuel out, and reinstall the spark plugs. It stumbles but doesn't quite catch before flooding and soaking the plugs again. I've heard that the 2nd gens plugs will work in a 12A, but what is better? I've tried both and neither seem to want to let it start. I may want to put in the manual transmission as I prefer manual anyways, and this way I can try pul starting. I still would like to see if it starts before that. If I pull the 2nd gen automatic out, what do you think I could get for it? it has about 167,000KMs on it.

if your using the secod gen ignition it wont spark at the right time, you dont have a crank anngle sensor. its what the FI engines use to control when to spark, that coupled with an insanely large ammount of fuel. i think you need some gen 1 coils, and a dizzy, along with fuel pressure regulator

What's a dizzy? How about a regulator? What are the specifics on what I would need to get? The guy I got it from said it was running fine before flooding, so it may already have one but, I am unsure what to look for. Thanks

Ah, never heard that term before. No distributor here. Yep the 12A was running in the 2nd gen before I bought the car. Would the regulator be at the engine end around the fuel filter, or near the tank? From the sounds of the replies and the fact that it isn't taking much cranking to soak the plugs, I am assuming that it is getting too much fuel. Can't hurt to install a regulator either way can it? If this is the problem thou, I'm not sure how it was running fine in the first place.

my first gen flooded a lot too.. in your case you need to change some things around .
change the fuel pump to a first gen pump cause 2nd gen pumps flow more fuel
carb fuel pumps flow like 4-6psi at the most .
check both of the floats in the tubs make sure your correct. 2inchs for the drop and 5/8 for the rise. also check the fuel valves you might have opened way to much . there the ones when you look down the carb they look like four circle valves that dont move..
and does this car have a choke anymore ???
i agree with getting a fuel preasure regualtor in there since it is a frankenstin car.
change the spark plug if you havent ngk works best for me.
that fuel cut off switch sounds like a good idea ive never had to resort to using one but it wouldnt hurt to have it.
hope this helps good luck!!!

The car has an automatic choke and crank angle sensor as well to work with the 2nd gen ignition. I believe I found a fuel pressure regulator too. It is hidden under the shaft from the steering wheel. It is cylinder shaped and has the main fuel host coming from the top of it to the fuel filter then to the carb. Can't think of what else this could be.

Floats as good too. When I rebuilt the carb one was a bit off and I've already adjusted it. The front sight glass is showing nearly half full of fuel, the other is too hard to see against the firewall. I will find a mirror just to be sure.

Thanks for hanging in there. Here is an update. It is starting to cough a little more each time it try. I put a little oil in the plug chambers to help the seals and also got a can of 'spray and go' or something of that nature. Seems close, was even still sputtering when cranking after the battery drained really low. Got to dry the plugs and charge the battery again once I get home. I may pick up some NGK plugs, but the ones I have look fine and should work, unless the NGKs are that much significantly better. I will try to get some pics up later today or tomorrow.

Still no go. Seem to be having better luck with the original plugs(ones on the left). It is tricky to get a picture of what I believe to be the fuel regulator. It is the cylinder with the hose coming out of the top. The shiny round thing on top of it is a quarter. I put it there because needed something I could see in the view finder. I threw in a few other general pics of the engine too.

Like I said eariler, Use two batteries when trying to start it, Get new Plugs, NGK work great, But I have had better luck with Denso's when trying to start a flooded auto.
