even though it was backfiring if i gave it more gas it really tried to go. a friend of mne told me it could be trying to vapor lock, but the fuel filter was not real hot i could still touch it.

I am not familiar with aftermarket carbs and I hope someone else can explain how to fix this on your specific carb, but I am almost sure that it is an enrichment failure if you're sure the points and timing aren't wrong. Manifold vacuum decreases when you punch the throttle open and if you're carb doesn't rich the mixture, you will lean out and get a backfire.
If it were the stock carb, I would say its the power valve. That also explains why it got worse. One of those once-a-week backfires could have blown it out finally and gave you the problem you have now.
