Keep trying, and failing, to start engine - what am I doing wrong?

[oblong]

Listen to Vitatroll. As far as I have seen the only reason for a hellburn to fail is that the fire isn't gaining heat quickly enough. Reasons for this include setting it up badly, losing the cans feeding it, bursting the pipes too early (when it isn't gaining heat as quickly) with oxygen or something, lag spikes, or somebody messing with the chamber/pump. Anybody who has this problem should change their burn chamber setup.
