My Tecumseh SnowKing SK100 has a new carburetor!

After about 15 years, I finally gave up on the original carburetor on my old snowblower, and ordered a new one and installed it.
I DID IT! All by myself!
Now- after much dicking around, I seem to have the main valve (on the bottom) and the idle valve (on the side) more or less where I want them.
Except - two questions:
- 1. It takes a LONG time for this engine to warm up. I had to keep the choke on for at least 5 minutes. Eventually it would run with the choke completely open. Mind you it was very cold out - about minus 10 to minus 15 celsius.
- 2. On the new carburetor, there is another small screw on the bottom of the float bowl, off to one side. The old float bowl did not have this.
So far I haven't dared touched this screw. What's it for?

You might try backing out the screw on the bottom just a tad to help it run better with the choke off. The screw on the side of the bowl sounds like the bowl drain. It's to drain the fuel out of the carb and doesn't need adjusting.
