This POV is for anyone who says: use the engine as it is out of the box.
What is the real life expectancy of this engine?
- 10 hours of operation? In this case you can actually use it as it is, it will perhaps be able to satisfy you without too much problem. Although I know some who have not made it.
- 100 hours of operation? Personally, I have not yet found a single engine that has reached this level. But by modifying the ignition point before TDC, by improving the lubrication of the lower engine, and by distributing the intake gases correctly in the 3 cylinders, there may be a chance to get there without breaking the cylinders, and without destroying the crankshaft.
- 1000 hours of operation? There is no need to dream, but that's what any lawn mower or chainsaw allows. For our little FG60R3, there are many parts that will have given up the ghost before, such as valves or valve seats, even if the cylinders, pistons and crankshaft are still alive.

It is true that they are beautiful mechanics, which produce a real beautiful melody, but we can not say that their design is perfect.

Or the manufacturer may be counting on the life expectancy which may be short for our models ... and in this case we are no longer talking about broken cylinders, or destroyed crankshaft pins linked to operating hours.
