I've owned three Tower 46 from when the first came out.
I've worked on a Tower 75 for three years whenever it had a problem including the carb.
I've put bearings in two Chinese ST 40's and one 61
I've owned 12 different Italian ST engines and some of them I worked on extensively in the past 40 years
I remember when I was a a kid not to long ago
,
I think everyone I knew owned a small 02 and a Jet-X engine.
I still find it amazing that as fast as they turn they hold up very well
