Bike shutting down when throttling

This is one of those "just checking" questions. I left my bike outside at a friends place for a few days last weekend. During this time 2 things happenned. 1) There was alot of rain - Severe downpours for most of the weekend 2) The weather got colder and has remained so since. Now, since last weekend the bike has changed its behavior a little bit. Before I would only need to use the choke for about a second and then the bike would be ready to go. Now, I need to run the bike for a good few minutes before I can use the throttle. If I try to throttle too soon, the bike dies. The bike idles fine.
Is this normal considering it's getting colder out? Or is it possible the rain caused some sort of problem with the airflow?

when you say it is getting colder, how much colder is it than before? ( a few weeks ago)

And Yes you have to use the choke for a bit longer when it is cold out, I have to leave mine pulled for at least 1 min before it will even idle

Well, lets just say its gone from t shirt to sweater weather. (Edit: I'm in Ontario too).

So, not being able to throttle while the bike is idling can be just a sign of it getting colder?

The bike runs ok after its been warmed, so I'm assuming thats all it is. I just want to make sure though.

Carbed bike definitely needs more choke time now since its gotten colder out. This past week, I've been riding in mostly 8*C (46*F) windy and rainy weather and this morning was 2*C (36*F) with wind chill making it minus 5 when I headed out and I pretty well had to put the choke back on some when stopped at a traffic light in order to keep the bike from stalling. It got better after about 3 hours and it warmed to around 6 degrees. Noticed the same thing with the other bike last season too when it got colder.

yup same here. been around 40's (till this weekend been in the 80s again) lately and I have to hold the choke for about 1-2 minutes before it wont die on me. Then again I can let go of the choke and rev the throttle for a little bit and it wont die on me
