Hi Dave,
Just read your post about 2-motor Baldwin FlyerChief truck screws. You mention in last line that the same issue / fix might be relevant to one-motor FlyerChief GP-7s. I had a truck screw issue with my new GP-7 ... photo and letter to Lionel in atch'd memo. Not the same as yours, but it was another truck screw length issue. I have been running my GP-7 without one truck screw because I can't find a suitable replacement ... so far, no engine anomalies. See atch'd memo to Lionel.
I still need a longer replacement truck screw for my GP-7 ... see atch'd memo. Lionel did not respond. I also wrote to Charles Ro and received no response. all I need is the right spec for a long replacement screw.
Regards,
Tom
