Got the packs installed and wired. Have spark on all three cylinders. Now the boat is acting like it's out of time, it'll fire but only for a second then backfire.
I checked timing according to procedure, with plugs removed and grounded, and the throttle wide open- it is perfect. However, there are only two marks on the flywheel, one is tdc so I imagine the other is 30°. I colored them black as the flywheel is white; the timing is set to the other mark.
I think the issue must lay with the trigger wiring to the packs, which has two orange and two green wires, as well as red and white/green wires. The orange and green pairs have me messed up, and there isn't a particularly accurate diagram.
I'm using the bottom guide. Any suggestions?
