Fourdees Bagnall rocking

[Tom Haythornthwaite]

My new Fourdees Bagnall looks great and runs sweetly - but rocks side to side a bit with every cycle of the running gear.  Any advice?  It seems so delicate and I'm so inexperienced that I dare not really try to adjust anything.

My guess would be a slight quartering issue.

I have seen this with a Fourdees S&K loco as well. That one also had the maker

Thanks Brian.

I think I need to select option two:  "see if it improves with running", as it's already been to a DCC vendor for a DCC decoder, so I expect the guarantee is void.  And I'm going to have to open it up myself to add some weight, as it won't even pull three coaches up my test slope without spinning its wheels.

Speaking of opening it up; I can unscrew screws below the chassis but what do I do about the running gear?
EDIT:  All I needed to do to open it up was to read the instructions...

Read the instructions  ???, what's the world coming to?
