The story so far....
Boy takes governer linkage apart and finds HF brand Loncin 212 can turn to 4900.
At this point I am left with the impression something failed or prevent it from turning any faster.
That part is fuzzy.
Engine may or may not have failed ( still fuzzy on that ) but its not realy importnt since small pieces of governer have been whipping around in the crank case.
Boy has another engine, he will swap it out....
He speaks in code because he does not want to to get in trouble with the moderators I guess.
Conclusions:
He has plenty of money and time combined with youth and a desire to see where the edge is.
With some luck he will grow old and wise learing the value of time and a dollar and with his testicals intact.
