ok I tried this other forum but no one knew/cared.
basically, this 101 which is now out of my hands... the friend who has it might be able to fix it him self as long as it's nothing too techy and whipping out a soldering iron.
Basically, the pulse width didn't get narrow enough... compared to my MC202 it only got to about half of what it should have. Under the hood I found a potentiometer around the middle. but after adjesting it, it didn't make it thinner and eventually after still turning it just clicked and went back to full square again so either I got the wrong potentiometer or something else bad has happened.
