New piston and sleeve puts you back to breaking in the engine. It's probably tighter and you're not going to get a good idle. Get it so it's richer on the idle and you need to keep blipping the throttle to keep it going.
there is no problem with it idling. It will idle on the stand til it runs through the entire 16oz tank (not that i would let it). The problem now is that with any kind of added throttle over idle its wanting to die. Im pretty sure i have it rich enough as i have fuel on the plug..IE 3-3/4 turns out. There is NO LSN on this carb.
