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

I agree. I when I first got this engine, I ran it for a long times at a stretch , stopping only for tank refills.
Until now I thought that I was probably abusing this little engine. After hearing that a five hour run is possible I've changed
My mind. While I haven't been able so far to reduce the firing intervals as others have despite changing the springs for some purchased from McMaster-Carr I've become satisfied with the rate at which my engine fires and will leave it
alone for now. My engine starts out fast at first and soon settles down to about ( I think) firing 40-60 times a minute. I think this rate will be useful for running a PM Research generator.
Thanks all for your advice and opinions. This forum has for me, and I hope others, been a wonderful learning resource.
Once again, thanks all.
