The flooding part may be the temps in combination with the altitude and
timing.
Depending on which passes your are going through
When my 82 was still air cooled stock
Eisenhaur tunnel (I70) route I would be slowed to as fast as third gear
would let me go and watch my oil hit very high.
Steeper long passes like woodland park in the south would have me in second
gear and oil nearly boiling.
Raton pass (I25) to New Mexico would have me in third gear and oil very hot.
Climbing the long slopes up to winter park vail etc. second or third gear
and extreme oil temps.
It is a combination of the 67HP engine trying to push a massive weight up a
long slope and the thinner air. The air above 6000 is supposed to take 10
percent power loss. When you only have 67 HP to start that puts you with
barely enough power to push the wind out of the way.
I tested various octane boosters over several of the passes as well as
higher octane fuels. Only effect was a hotter engine. Exactly as VW stated
in publications.
After numerous times of trying to keep my poor engine from melting down I
finally went with a subie mod.
