Moki 250 not starting on last event of last season.
Got the engine back from TBM.
There was a loud 'clunk' when turning the prop.
TBM's moki tech opened up the front and back of the engine. He didn't find any damaged parts but a front bolt on the front shaft needed to be tightened to move the shaft forward about a 1/16" to keep parts from hitting each other.
UPS was a little rough on the engine (must of dropped it) as one bolt on a rocker arm was broken as well as a bent push rod. Called TBM to get new parts so I can replace them. The shaft of the engine went through the top of the moki box and the in sides of the box cardboard was beat up pretty good from all the movement. The engine was secured to the original wood base but the engine could move up and down in the box since it went through the moki box (rough UPS handling allowed the shaft to move vertically since the shaft went through the top of the box).
My second engine came with a donut shaped bubble wrap to keep the engine from vertical movement( my previous engine did not have the extra padding). I sent the engine with the extra donut wrap but it wasn't used on the return. I would suggest all mailed moki engines be mailed with this extra donut padding. Using some twine or box tape to secure the top of the box to the bottom, also wouldn't hurt.
