OK,

I have run the first tank....OMG there is a lot of raw fuel coming out of the crankcase vent line. I assume, (hope), that this will be less of an issue when I lean it out a bit. It's fairly cool here so i think 10-15 minutes between tanks should be good. Keeping the RPMs around 3k for the first tank...barely 10 minutes (a little less). I hope this thing will run a bit longer than 10 minutes per tank.

Thanks for all of your help so far!!
