226/6 problem

Thanks, I did rebuild the carb before I took the car off the road. It is a Carter 2bbl and pretty easy to install the kit. I really did not adjust the floats just put them back in the same way. I also had to turn the distributor all the way to advance to make it run.
If I installed the timing chain one link off would this be the case?

if it is misfiring it will want to spit raw fuel out the exhaust. if it is not in time the engine will shake and misfire, and it may even want to backfire out of the carb
