I started below the 1/4 mark and My low fuel light came on during my last run or maybe 2nd to last and i didn't have any problems. Although i don't like being that low on gas so I plan on showing up with at least 3/8's of a tank in the future. but at my skill level i don't think the weight is much of a factor.
Oh and Joey,
The yellow (300ZX?) 13 EM had some more oil come off it on its first run. it was smoking at the line for its 1st and 2nd runs. I heard something about it being oil on the rails on the radio, but it was windy and I never asked the owner afterwards what really happened.
So there was a small delay on starting for the kitty litter and sweeping. and part way through some weird small green bugs flew in and started to annoy everyone. Then came my turn to drive.
Lots of fun! I found the course challenging but also really fun! I think my best was a 47.4 something, and i got beat with a 46.x something . not quite sure what the Karts were running i know i saw one 40 but i don't know if that was a slow or quick time for them. (or if that run was clean)
