Heating the full saves gas because of better vapurization and more compelte burn.
Some guys even sale gasoline heaters (not the ones for diesel) for fuel saving.
I routed the steel lines of my 235 close to the head but it is not heating enough - got to improove that after the hollydays.
you need at least 180-190 F to save gas.
Never had a problem with vapout lock because the holly webers have a bowl vent, that I rout to the air cleaners.
