Hi I have received an old and rusty Cox Orion, model 25J1, as a project. Nothings rotted out and everything seems to be there, the engine, steering and drive are not seized. But, the drive chain was running over the OUTSIDE of two pulleys on arms which are connected by a spring. The pulleys seemed redundant so I moved the chain to run on the INSIDE of them with the spring providing tension. However the chain now has no slack what so ever. Could the chain be wrong, it doesnt seem to sit down on the large drive sprocket too well, or my routing of it incorrect. Any photo of the correct routing would be helpful. Thanks
