Hoping you can help me here a bit Don everyone says your the expert. I just bought a Attex Superchief with the Chaparral g50b 494cc engine.
the Past owner said they installed new pistons and rings bored 20 over and could not get it to start. spark was going in and out so I cleaned wire
connections traced ever thing down and have good spark all the time just wont start or even try with fuel or either sprayed in cylinders. The compression is 80 psi on No:1 and No:2 is 90. If the No:1 is on the flywheel side of the engine. I have the points starting to open just BTDC only when I look at the flywheel moon key its at BDC for the number 1 its been many years that I worked on 2 strokes and I have had a number of Strokes myself so I am not as good, sharp or quick minded as I used to be. Anyway I guess my question is could the past owner some how installed the pistons 180 out of time.
