I live in new york where it has been a relatively mild winter..My 73 vette is stored outside underneath 2 car covers..
I take it out every 2 weeks..Today it started ran for 15 seconds than cut out...I tried everything too start the car,starting fluid,opening up the butterfly as I pressed all the way to the floor-nothing...
I am pretty sure I am getting spark,never had a problem before...I figured I would leave it for tom. morning..Any tips or suggestions before I try again tomorrow?
Any tips?

let it sit a while would be best. You will have time to cool off also.

You might have to replace the plugs if they fouled. On old trucks with Qjets, we just floor it and crank it!!

replace the plugs , or of if moneys tight use a propane torch to burn off the wet gas & oil film while you hold the plug with an insulated glove then use a sand blaster or wire brush to remove as much deposit residue as you can then re-gap the plugs and re install with anti-seize on the threads

I would concur with cleaning or replacing the plugs.
However, with todays fuel, flooring the footfeed is less effective than not touching the footfeed! The theory behind flooring the footfeed was to allow the unloader circuit to open the choke butterfly and the throttle, and allow the air pump (another name for engine) to blow out all of the fuel in the intake, air cleaner, etc. Unfortunately, the volatility of todays fuel in such this method may never clear the fuel.
By not touching the footfeed, one leaves the throttle completely closed. With no fuel coming into the intake, the air pump CAN clear the excessive mixture. Generally 5~7 seconds of cranking, followed by GENTLY pressing the footfeed (so as to not activate the accelerator pump) and the engine will start.

Good carburetion is fuelish hot air!
The most expensive carburetor you will ever buy.....is the incorrect one you attempt to modify!

Thanks for all the input...
Actually went back the following morning took off air cleaner and opened butterfly to let some air in...
One shot of starting fluid and cranked it with no pedal..Went over on second try....
Pulled a few plugs and they are a little dark...Car runs great though..You suggest chnging the plugs? There is only about 100 miles on them..
