Good Afternoon, I recently purchased the subject line k4, it is dc only. It is a very nice engine. But when running it appears that the side rods rub and catch on the plastic insert of the drive wheels? This causes a bad wobble while running and intermittently or for the engine to stop.

Has any else run into an issue like this and is there a fix that I can accomplish w/o disassembling the engine? Does anyone have a procedure or step by step fix for this?

Thanks

Brett
