In between moving machines around today to accommodate the skimmer, I tried moving my MG5, firstly it was a pig to start and when it did it would not slow run, I suspect either slow running jet or possibly yet another condenser failure. The main issue was that when I tried to move it the left track was locked solid, no amount of rocking back and forth or big bars to lever it would free it off. This has happened before and went away, it is not the brakes, anyone had a similar experience ?
