I had the car running and ideling and driving then it sat for about a week and it wouldn't start and then I swapped plugs thinking maybe they were that fouled and I got it to start after about 3 min of constant cranking. It had a big miss and would only run as a add more gas as soon as I pulled my foot out of it it died. I tried to start it again and it wouldnt for the life of anything.

Sounds like sticking float(s). Opening the throttle is allowing enough air to get in and allow it to run, then when you let off there is too much fuel to run again.

Tap the float level screws, some times it works, I would pull the bowls off and clean them. Mainly the needle and seat. After sitting, today's fuel leaves powder in the system, and causes the sticking.

It could be clogged jets as well.

Sounds like a vacuum leak to me. I've had backfires blow the PCV hose off.

ok ill take a look at the carb tomorrow thanks i need to do a rebuild on it anyway

so i got it to stay running for a bit it wont idle and from 1k to 3k it blows smoke out the exhaust but up top above 3 it runs fine i played with the idle circuit a bit but i cant get it to idle at all.

Now that sounds like sticky floats .

Above 3K you are almost certainly out of the transition circuits and into the main jets. So maybe something physically wrong in the carb, a bad gasket or power valve seal, clogged air bleed, etc.

This happened to me and it was floats sticking. Too much fuel leaking at idle.

Be a good investment to get some fuel bowls with some sight windows , or some sight window screws ,so you can see the fuel level ,great for fine tuning also.

OK so after a carb rebuild and new needle and seats its still there then I borrowed a timing light from a friend and 3 coils arnt firing the back three on the passenger side I swapped one coil with the drivers side and it fired so I somehow blew three coils anyone know the reason for this

Maybe bad before you got them, exposed to water maybe?

machoponcho

Not where the serial port cable hooks in.

machoponcho

thats exactly what it was then thanks for your help looks like i need new coils and a coil cover

machoponcho

OK so I bought all new coils got a deal on it and it seems like the miss is still there but I can't get the engine to start right... it will start when its been sitting after I crank it for like 10 seconds and hold the gas at wot. But when I start it the miss is there so I killed it then it won't start for anything and the starter is not even turning over. Its a brand new starter and I don't understand how it ran so well before and just because it sat it won't run for anything now.

take off the air intake and let the fuel pump run and see if its leaking fuel out of the boosters. Then you will be able to tell if the floats are sticking for sure.

Nope its not I just bought new needle and seats and did a full rebuild ... I usually have the air cleaner off I haven't noticed anything.
