OK, I finally installed my L28 and everything is hooked up. Turned it over and its popping and backfiring and wont start, which tells me theres a timing issue. Its a 75 280z with triple webers, stock dizzy, MSD 6al, and Blaster2 coil.
Here is what ive checked so far:
Its getting fuel
It gets spark
Firing order is 153624
Set motor at TDC (compression stroke)
Pulled dizzy cap and its backwards. But it wont let me turn it 180 degrees because it only lines up one way. Am I missing something? Ive heard of guys switching the firing order on the cap. Now I know Rebello put on a new cap and rotor and modified the dizzy to wire up the MSD. How would it be backwards? I really hope this is something dumb that i'm doing. Here are pics.
