Lost power all of a sudden. 273 commando.

Have you checked your ignition yet for a strong spark?
How much difference in temperature and humidity since you last drove it and it was running well?
Have you checked your float levels (maybe it's running a little lean?)
Is there any other difference in the way it runs? (operating temp)
Is your air cleaner dirty?

1. No, this I have not really checked actually.
2. Not really humid, but very hot, like 29 degrees celsius, more then twice as much as last week.
3. No, but is it likely that would be the cause all of a sudden when it ran well just one week ago? The carb ran great out of the box, brand new. I did a little fine tuning and it was a big improvement over the edelbrock I had before.
4. Besides the lack of power as described, no. It runs great. It did run hotter, but it was really hot outside, so it usually does.
5. Air cleaner brand new.
