I am not a mechanic, and all the mechanical knowledge I have is very limited to the textbook and the POH. Any help is GREATLY appreciated!!
Go back top the POH for a moment. What does it say about how many shots of prime to use? If it's like the one I have, it says 2-6.
If yours says the same, think about it: You are trying to start an engine that was sitting all night in below freezing temperatures on a day where you are just above the guideline for using preheat, and trying to start with the bare minimum amount of priming.
It could be a weak battery or a weak starter - those tend to worsen with cold temperatures. But your first step should be to use an appropriate amount of prime for the temperature of the engine.
