Look on the distributor cap. Mine has the numbers stamped into the plastic.
Also, the firing order will 99.9% of the time be 1-3-4-2 for a 4 cylinder, so you definitely want to arrange it in that pattern. I'd just try it in all 4 possible locations of 1-3-4-2 until it started. Also, you may have flooded your engine with gas by this point, so try giving it gas when you start it.
so you had a 3in muffler aswell?
and the 4,3,2,1 setup i got runs fine is it not supposed to??
