Took it apart...pretty simple and basic 2 stroke concept...
No scoring or groove wear.
But it was wet around 1 way that gasket and silicone was flakey and wet brittle too
Now on the crankshaft there is a groove towards flywheel is there supposed to be a o ring There?
Carb o rings look bad as well
So I think I had some major air leaks and running pig rich was the only way to get it running
I might be wrong but it's worth a try to reseal it and try again
Also the bottom screw under Hsn how do I reset it?
And could this carb be suspect as well
