How are you determining that there is no spark when the spark plug is installed in the engine??

If you can get it to run only on choke then you are not getting enough fuel through your carb. Your main jet is either dirty yet or if you have an adjustable jet you are set too lean and need to back the screw out. I do not know what carb you have as you do not have your model numbers of the engine listed. I would say you need to look at the main jet first and clean it real good.LOL
