My Legacy NYC Geep was acting erratically. Starting, stopping sputtering. I was worried if the board was going .....I knew the track was not an issue.....it had been recently cleaned.
Luckily, I thought...........could it be the wheels?
I put the engine in a cradle. First, I cleaned the rollers; then, the wheels.
I was amazed at what I found......
It runs fine, now!
Since I typically run engines for a few weeks and then put them back on the shelf, I need to get into a habit of regular wheel cleaning when the run time is done.....
