RE: Dle-20 Blew up....
This engine has a static timing of around 38 degrees before top dead center, the advanced timing is way too much as well, the number escapes me now. In my world that will break a crank and tear bearings out. The engine is trying to run in reverse and it would if it had a lower compression ratio the compression ratio of 10.5 to 1 and 38 degrees of static timing are engine killers. I took my timing to about 30 degrees where it should be and I see no difference in output. Sorry about your engine and I hope and trust you will be able to repair it
