How much flame is normal on turbine startup? I'm getting 8-12 inches of flame from most cold starts on my Kangaroo using straight coleman propane. I've seen obvious hot starts at some events where 3-4 feet of flame shoots out of the tailpipe. Mine doesn't approach that. I've only had one aborted start that I know was due to EGT. Is it possible to get a start with no visible flame on some engines? What, if anything, can be done to reduce this?
