Problems with Honda no-start

Hello, first post here. I have a Honda 96144000300 with the GCV160 engine. I am having problems with it starting, this is what I have done so far:

- the previous owner had a new OEM Honda carb installed before I bought it a couple of weeks ago. To be sure that fuel wasn't the start issue, I sprayed a bit of carb cleaner into the carb throat and tried to start...nothing. I went ahead and pulled, disassembled and cleaned the carb anyway. Flushed the tank and lines and added fresh fuel.

- So, now I know it is either air, spark or mechanical

- the plug is brand new

- the air filter is brand new

- I did a spark check and I'm getting spark both from the coil and the plug through the coil.

- I borescoped the cylinder, and the piston is intact with no damage.

- I disconnected the kill switch and tried to start thinking that it could be a bad switch, still nothing

I can feel and hear compression when I pull it over. Can a coil give spark and still be too weak to start- or are coils a "either it works or it doesn't at all" kind of thing? Any ideas on what to check next? Thanks in advance for the help!
