Matt is a genius in doing the repairs

 Matt repaired the rear wheels and the brakes but his biggest problem was the third wheel - it would not lock.   How he repaired the thing was pure genius.  He just removed a pin and then wiggled it a little and then the thing worked.

Seized engine (for replacement) or just a busted bearing for PTO clutch

 This post watched a video of a lawn mower that does not turn.  The battery was juiced up and oil was added.  Still the engine would stop.  There was a heavy resistance in its turning.  

Here we see the importance of past experience and critical thinking.   The mechanic postulated it could be the PTO clutch assembly And true enough, there was a busted bearing that made it hard for the engine to turn.  When the clutch was removed (and consequently the bearing replaced) the engine turned well.   

Great repairs.  Great savings for the lawn mower owner

Black nail polish has been useful in touch repairs of carbon frames, rim brakes and RD

 A P40.00 black hair nail polish has gone a long long way in making cosmetic touch ups of scratches and exposed bare metals of the following:

1.  Rear derailleurs

2.  Carbon frames

3.  Brakes

4.  Chain ring.   

You keep the bike still looking good.
