Edelbrock carb cleaning question

[MR.BOWTIE]

.....I apologize if this has been addressed already (I'm sure it has), But my old lady was taking my 71 c10 350 to work( isnt it always when THEY use it?!)
went around a corner and it died, I changed the inline fuel filter, but it would not idle, just lots of smoke, as soon as I gave it gas it would flood itself out. I noticed gas in the carb base and dripping out of the left(autochoke) side linkage. Towed it home, took some carb cleaner to it hoping it would help. It was running fine before this. I have an edelbrock 1405 on performer intake. Edelbrock tech said that it was probbably my needles and seats to clean them, said thats the problem 90% of the time. Then to check my float as well. The big question is how to do this, I am no mechanic, is there a good technic for this procedure. He said that was probably it since it happened quick, not over time like a fuel pressure issue. I did ride on one dusty road a week ago, I also have the open all around air filter. Thanks for any help, awesome advice on here.
