Start by cleaning all parts, especialy the carburetor, and check the
condensator. New spark plug can't hurt either.
It could be that the fuelcarter oilrings are leaking. 20 second runs are
usualy due to that or the condensator.

Wouldn't know, but it seems highly improbable to me.

The 50 cc doesn't limit the speed to 30 mph. It's the way the fuel is
lead to and from it. And ofcourse the way all parts function together.
My puch for instance has it's original settings but does 35 mph anyway.
My honda c 50 does 41 mph.
And getting everything optimized will result in higher speeds.
A friend of mine has a hobby in classic racing in the 50cc range. His
Jamathi minarelli with moto morini engine does 109 mph (174 kph) and
with the new gearbox he's working on it'll do over 125 mph. My point, 50
cc wont limit the speed.
