I noticed the fuel line disconnected, and the disk nut loosened.... Fixed those and try again.
I ran but something is wrong.
I think carburation, spark and maybe exhaust backpressure........

I can check points, put Victa carb on, and put a tin can over mufffler to make more pressure.....
Anyway here's the test run
