Got a new engine this weekend!!

[Tex]

Richen the needles a full turn and try some new fuel.

I wouldn't do that... How would you know to richen when you don't even know how it runs? It can stall from being too rich also so I wouldn't jump to any conclusions.

I wouldn't change the gas unless it wasn't taken care of.
Don't store it on a concrete floor
store it in a cool, dry place... no direct sunlight
don't leave the gas container open for extended time (fuel bottle, or gallon)

As long as you didn't do any of that with your gas you should be good.

What's the temp on the motor at running tempature?
Does it seem to bog on the low end or high end?
Does it have super crisp throttle responce?
How is the Idle? is it too high or too low?
How long does a tank of fuel last?
How is the smoke on the low end and high end? nice trail the whole way? Or no smoke the first 1sec you pull the trigger?
