handheld IR gun. I use it alot at work with EMD and Detroit engines. It isn't 100% accurate but it's pretty darn close.
I'm used to balancing an engine with both exhaust gas matching and firing pressure....

I'll mess with the idle screws when I get back on land (3weeks). Any other suggestions? I'm looking for ideas so when I hit the house, I can hit it with ideas.

Thanks guys!
