airbox issue

Hi there,
I'm new to the forum and have an issue i hope someone has an answer for me on my 1983 911sc.
yesterday i went to check my timing and saw it was at tdc " i recently replaced intake boots and injector o-rings" so anyway i adjusted it to about 4 btdc and car seemed to run fine, so went for a short cruise. on the highway all was good till i got off the highway into the city. Then things started going wrong , backfiring with no low end power. I managed to baby it home and let it sit overnight.
Today i went out to check things out. I tried to start the car and all it would do is back fire. so i rechecked the timing. since i could not get it started i static timed it to tdc and it started right up but had high idle.
I pulled off the air cleaner and noticed fuel dripping off the arm of the air/fuel sensor plate and the car smells rich.Did i blow the coffin gasket or what? any help would be greatly appreciated.
