1990 ds will not start after top end rebuild

[Crack]

Hey everyone,

I just did a fresh rebuild on the top end on a kf82, was super easy went real smooth, put it back in the cart all it does is spin and will not fire. Have spark, fuel and compression is about 170. When I pulled it I sprayed it down with engine degreaser all over then power washed it, I plugged every hole so no water would get inside. Dried it off dismantled it ran everything over a wire wheel on my grinder, sprayed down with break cleaner and wiped clean and let it fully dry before re assembling. Only thing I can think is maybe the timing thing on the wheel got screwed? Thoughts? Any help!?!??!! I’m lost lol
