Mike,

What is cold in your part of the country? A few simple diagnostic procedures will save you some $ and learn for yourself.

Is the choke hooked up?
With the air cleaner removed, does the choke blade actually move to the correct position?
With the choke open, when moving the throttle from closed to open, does gas squirt into the inside of the carb. indicating the accelerator pump is working?

Good luck,

Ed
