probly a stupid question but i want to know befor i start messin with stuff. can you make your truck runaway by turning the star wheel. and how far do you turn it, and does it get alot more smoke.

 

nope turn the star wheel as much as you want it won't make it runaway.

 

You can remove the star wheel completely to get even less spring tension on the Fuel pin... this will yield more low end smoke, but not the type of extra fuel that would cause a runaway. That will occur if you crank the Full Fuel screw to the max.
