Hey guys, serious question - these early scooter engines from what I read were bullet proof.
Yes, to an extent. Consider that these were designed to run on crap oil and much, much slower speeds.
If you want an engine to run it's best, no leaks, and keep up with modern traffic, there is a learning curve to making this a reality.
The old two stroke engine isn't for the faint of heart and you're doing a great job. You got this.
The folks that have done a couple of engines and have found what "works" are sharing their knowledge here on this forum. It doesn't mean it has to be done that way, or this way. It's what works for them.
Lots of issues can creep in, like a tiny oil leak, or air leak, or it's stalling, or running rough, or stalling, or, or, etc, etc.
This is why we are all rooting for you and putting in our two cents.
