Bad timing or plugs wired wrong will spit up thru carb usually. After making sure plugs and timing are correct and still won't start, disconnect input to fuel pump thus no gas to carb, let carb dry out awhile, then pour A VERY SMALL AMOUNT OF GAS down carb throat (teaspoon)(coke bottle cap full)and turn over, should start and run a few seconds. Have fire extiguisher at hand for safety. If it runs, rebuild carb and/or check fuel pump flow. Check float level. Since I don't know what you have or what year, check ballast resistor. Be sure to always include year, model and engine in your posts!!!!!! Remember you must have strong spark not just spark. If it does not run after teaspoon, try a little more than that,(tablespoon) still not start, you have eliminated the fuel portion as the problem. Now it's either spark, timing, resistor, distributor or distributor hooked up wrong, a short or something real big, as in valve train, cracks, etc. Make sure choke is full open during fuel experiment. I don't know if sputter means some firing or spitting up or ?
