I think this engine can be improved by disassembling it and
control the timing - the slide must be in the right position!
On the other hand, 1 bar is fine for a new engine to break in.
Perhaps there are also leaks in the valve body?
The lack of a properly sized exhaust pipe is a major problem
and should be corrected by the manufacturer. The "naked" look looks
better than the faux patina. Arnold
