Exhaust smells strong?

[Rockbronco67]

This is steming off of EFIBRONCOMAN thread and I didn't want to highjack his.

Someone mentioned exhaust smelling strong. When I start my rig up, you pretty much have to leave the garage. The exhaust is not black and the engine seems to run good. I thought it was strong because it doesn't have any cat and a straight through muffler. How much smell should be expected? What do i need to adjust? How can you check your A/F ratio?

Don't forget, when you first start it up it's in open loop dumping fuel, it takes 10 mins (or there about) to reach closed loop. I'd be more nervous is you were saying it was watering your when it's warmed up.

Isn't that a real lean condition?

Pull a couple of plugs (the easy ones to reach) and see what you got.
