Is the heat ever an issue, given the short run times? Does fuel choice mitigate those issues somewhat?
I would agree. The run time would be under a minute and you should be fine. If he does go with alcohol, that would buy him a little more time.
We ran into the problem of not being able to get enough heat in the engine, especially if it was cool outside. Anything under about 80° and the carbs would frost up.
