I know this is probably getting old, but I have no idea where to start, granted this is my 2nd ex, but this one actually has crap done to it and its been so long since I last had one.
We want to fire this motor up this weekend just to see if it runs. The mods are WB Track cam, high comp (dont know ratio) 416, it has aftermarket valves if that matters, springs and retainers (not sure brand), its ported as well. Really not sure on the details, the motor has been sitting for 5 years and my buddie kinda forgot who did it and all. All the head says is PR so were not sure who that is exactly.
Regardless where should I start jetting wise.
-416 high comp
-wb track cam
-ported
-valves (if that matter)
-full yoshi exhaust
-stock carb (for now just to get it running)
at about 900ft above sea level as well
Im not looking for exact jetting, obviously I have stock jets in now and need bigger ones but not sure HOW big to go and needle position.
