I have a no start problem to which most people were said get new plugs

I put new NGK plugs, didn't start so I pulled on of the plugs back out and it is soaked gasy smell, but dark look oily.

I know it is premix but there is a fair amount of oil

Thoughts on why still no go?

I took some gas from the line to make sure it is good and I can light it up no problem, but if I put open flame to the soaked plug, nothing happens. Too much oil? Why?

Perform the deflooding procedure. Before you attempt to restart, take and spray either carb cleaner or starting fluid down the primary barrels of the carb.

Oil/ gas fouled plugs do not like to fire across to the electrode, clean them up. Spray them down with brake cleaner, blow dry with compressed air of burn it off, sand blast them lightly if you have a blast cabinet before and after blasting

Perform the deflooding proceedure, pour a capfull of engine oil down each primary barrel of the carb to restore compression since the extra fuel may have washed the pre-mix lube from the housing and irons.

If you are running premix, and the car sat for a while, the fuel could have evaporated from the carb, leaving the oil behind.
As for the plugs, spray them with carb cleaner, or brake cleaner, and dry them off, before putting them back in.
Then try doc's advise.

Have you verified that you have spark to the leading plugs?

g prime

I have spark to all plugs.

Ok, lets back up and do diagnosis the way it is supposed to be down.
What lead up to the no start problem? And don't be shy with words. Meaning I need the whole picture.

There was a cold snap too which the car was improperly plugged in. I tried it that morning before I went to work, it almost started but wouldn't stay running. I managed to drain the battery and figured I flooded it.

When I got home I removed the plugs and charged the battery, made sure the block heater was working, plugged it in for about 12hours. Then tried it the next morning, didn't start didn't even try very consistent crank. Repeated that process a few times until I could get new plugs.

Got new plugs, while plugs were removed I cranked it over with fuel not going into carb, could hear some compression and whatever is in cylinders puffing out, installed plugs and tried. No dice. Removed plugs saw oily wetness, took some gas and it lights w/ open flame what was on the plug doesn't. Unflooded it down to a T w/ instructions found on site. Also tried starting fluid a few times, before cranking and during cranking.

Well, I'd say to go ahead and remove plugs again. Disable the fuel pump. Crank it over untill you believe all the oil/gas is out. Get a oil squirt gun and put some oil in it. Squirt a small amount of oil into each trailing location. Put the plugs back in, spray starting fluid or carb spray down the primary barrels. Use another vehicle with jumper cables and hook it up to the 7, put the negative jumper from the jumper vehicle to the 7 at the alternator bracket. Leave the fuel pump disconnected and crank the motor. That's all you are looking for at this time is to see if it will fire up, it should run then die.

If it does or doesn't what does that mean? Will try tomarrow when it is light again.

If it does not it means that you have a problem with the igntion system. If it does it is pointing towards fuel delivery issues.

Or it could mean you have a compression or cranking problem.

You will just have to trust me on this and let me know the results. Too bad I am not closer to the needy 7 population.

It started so... I know **** all about carbs.

I am going to try changing the filter and cleaning the little inlet ones, beyond that what should I look for? Pressure? I get some b/c i rerouted the lines to clear the cylinders and know I am getting some fuel.

Rx-7Doctor

Well you probably just restored cranking compression. As long as you verify that you have an adequate fuel supply to the carb it should start from now on.
You can do a volume test per the FSM and verify that it is within specs. Also make sure you have the fuel hoses routed correctly to the carb. Do the volume test after you replace the fuel filter.

g prime

I get about 2.5 to 3PSI cranking

I doesn't start with everything hooked up and oil put in trailing locations.

g prime

any more suggestions?

When you rstored power to the fuel pump and tried to restart did it flood again?
