Hi. Apologies in advance, I'm a noob to this. I've had my ts4n for about 20yrs but its been in the shed for most of it as about 15 yrs ago I let my sisters ex mess around with it as he said he was an expert. On return to me he had removed some parts to make it lighter, not sure what other than the on/off switch. Since then I've had a problem with steering being reversed, steering left it goes right and vice-versa. Not got a clue what he's done but really want to get it driving properly and get back into it. Any ideas are greatly appreciated please.
