Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

If you don’t want to do any modifications to your engine, just switch over to a gas burner    You’ll get much better speed control by fine tuning the flame than what you will with an inline throttle and far longer run times as you won’t have any wasted steam.

Agree with Nick here.

BIX burners are a bit of an investment up front, but you can use them 'forever'.  Makes running on live steam less of a chore, which means you'll probably run more often!
