I fellow high-altitude roadster buddy re-routed his to the front of the
rad and it made no difference. Before overhaul, I pulled the gas-return-
-vent-valve-thingy line off of mine while my engine was madder'n snot
vaporlocking, and the gas was COOL coming out of there. So, I think my
problem 'boils down' to the float bowls...
