I have a 85 Lt80 installed a new piston and rings along with a new jug.
It fired up but had no pwr
cleaned carb ran great but now will not start.
Cleaned air filter and houseing
where to from here??

 

Maybe do a compression test. Also maybe re-check your gaskets to make sure none have torn or broken during the re-installation of the cylinder/piston. Just suggestions, I'm definately not a tech or anything[img]i/expressions/face-icon-small-confused.gif[/img]

Clean the carb again, maybe something else got in.
Lemme know.

 

maybe a bad case seal?
