Expert:  Jeff Policky replied 3 years ago.
did you replace the piston rings?
Customer: replied 3 years ago.
there's only one ring and yes I installed a new one with the new piston.
Expert:  Jeff Policky replied 3 years ago.
with out honing the cylinder you new rings will not seat in to the cylinder well. making for a little loss of performance and loss of ring life. nothing to cause a no start. is the piston installed with the arrow pointing to the exhaust port?
Customer: replied 3 years ago.
It is... I believe it's a fuel issue. I cleaned the carb, all looked good. didnt replace the reeds. I think they work either way...no such thing as upside down? Plug isnt very "wet" when I pulled it to test for spark. Thoughts?
Expert:  Jeff Policky replied 3 years ago.

reeds all depend on what style they are. I agree on the fuel issue. test this out by putting a 1/8 of an ounce in to the spark plug hole and see if it will try to start then
