Cold Start

Brrrrr! 17 below this morning and she started but she sure didn't want to. I ended up having to prop the choke plate open about a 1/4 of an inch and pumped the pedal about 8 times. Is it just the cold or is my choke not adjusted properly?

Sound like your choke isn't adjusted just right. Doesn't matter much how cold it is, i pump my pedal once, choke kicks in and high idles at around 1200rpm i believe. Your choke butterflies should be closed when starting cold, less air, more fuel, then they gradually open as it warms up. Did you have to prop open the throttle plates you mean?

A spray of ether down the carb would help with severe cold starts though, and make sure your battery/ignition is getting a strong spark.

It was the throttle plate that I propped open. I suspected the choke wasn't adjusted correctly.

I've had the same problem. It was recently adjusted (idle and choke), but fighting me to start once it got colder a few days ago
