Since you have the timing cover off...put a degree wheel on it and find out where the cam is. Guessing where it is by going off the marks on the timing set isn't gonna do you any favors.
If it's not where it should be, correct it and try again.
If the cam is installed OK, put it back together, then adjust the timing by hand and see what happens.
Do this before you screw w/ the carb. twocents
