@WinstonB posted:That’s my point exactly. Only one chuff per driver revolution. When I manually activate the good chuff switch, it triggers a chuff each time. I need to examine the cam. I have an old Lionel Consolidation, with the lever that’s pushed by the side rods moving forward that does the same thing, by design.
Sorry I didn’t get to looking closer at my L1s yesterday. Got the Q1 in the way at the moment. My curiosity is piqued though and I never realized the cams were bolt-ons. This engine has been very trouble-free so I haven’t been into the engine yet. I do need to adjust the chuff phasing though as it triggers on the 45s.
I’ll bet Scott has that switch available as a spare part or if not, Digi-Key would.
