No, it's DC. Should have said that.
Have you tried to run it without the shell on?As I have converted several C628 chassis to fit in E44 shells, I am quite familiar with it.The slow-accelerating motor is one of the most common issue that I have.After hours and observation and testing, I have found out that it is caused by the motor rotor rubbing the shell.This can be fixed by centering the motor cradle (black plastic frame around the motor).If it still rubs, super glue thin pieces of styrene on the two sides of the motor.
I had a similar problem with mine that I believed I found the answer to on the old Atlas forum. Their is a universal cup on each end of the motor shaft that has a tendency to split and then spin on the motor shaft. I think I fixed mine by putting some CA on the part but I think you can also get replacement parts from Atlas. From wjat I recall this was not an uncommon problem.Martin Z
