how sure are you that you set your timing correctly? it's not something that you just guess at, and if you adjusted it once, how do you know that you set it back where it had been?
I would say that you are not getting gas, unless your spark plug is soaked, then your gas is not really there, either that or you choked it to much, flooded it, and then you would not be getting spark.
you put a new filter on an old line, that is never a good idea, old lines shrink inside over time and the smallest air bubble will then give you a sort of vapor lock, and putting that new filter on that old line makes it that much easier to trap air in there, so unless you know you are getting gas by taking the bottom off the carb and having gas run all over the place, it's not really there.
you don't have one of those little banjo bolts on your carb with the hiden filter screen in it that could get cloged with a spec of dust, do you?
