lol beat me to it. Glad I'm not the only one thinking thatYou might be in over your head here bc this doesnt make a lot of sense
You said it starts and runs on starter fluid which means you have spark. But then you said you confirmed that the fuel is getting sprayed into the cylinders? So you don't have spark now but you did before?
Bc if you have both and its not working its probably going to be your compression
