I would imagine this is the same for the 3100 series correct?

Nooooooooo, totally different motor for starters. A 3100 is a 60 Degree V6 for one (a 3800 is a 90 Degree). The firing order on a 3100 is 1-2-3-4-5-6. Completely different motors......

yeah, that one is considered the odd fire...so nope...not the same.

So the firing order for a 3100 is 1-2-3-4-5-6 so how is the motor set up?
Does 1 start on the right faceing the motor? and so on?

I think on the 3100 its
123
456
