I just started the break in period on my 80cc motor, everytime it is on it misfires heavily and typically runs better on choke. When I am able to run off the choke it bogs heavily at low rpms and is more responsive at higher rpm's.
My searches indicate its running lean because it runs better on choke, and will usually die if I move it off the choke setting.
So far I have:
-Tried several adjustments of idle screw
-Sprayed starting fluid around carb. area to check for leaks-it didn't seem to have any.
-Taken apart carb. and sprayed everything to clean it.
-Tried different ratios of gas(from clouds of blue to clear exhaust)
-Changed spark plug
Regardless, it still misfires or sputters to the point the bike lurches back and forth. Does anyone have any ideas why its running so rough. Also, how fast should the fuel go down the fuel line because it tends to just sit there for awhile in the fuel line. I know its supposed to be fuel efficient, but I'm thinking the carb may not be giving enough fuel.
Thanks for reading and responding.
