May take 2 or 3 tries but it will fire up. Heating intake air also improves fuel economy but I have found a greater tendency to go into detonation especially when ambient temps. go above 60 deg F. If you run a dedicated water or water/methanol system you can effectively supress detonation with even the lowest octane fuel.
