my buddy gave me a kazua falcon 90 that he had let sit for 2 years. i cleaned fuel systems took apart and cleaned carb ,ohmed out all wires, safties, cdi, etc... it is so inconsistant its weird. sometimes it will crank good idle good and run till it warms up and then die and not start back up. sometimes it wont even start. sometimes it will crank but not idle good for nothing.. sometimes it wont crank or do anything... also the carb seems to have no response to any adjustments. olny thing is i have not replaced the plug.. ps thank for lettin me be a member yalls site kicks as* my kids and i are just getting in to wheeling so i hope to have a big one for myself soon an help would be appreciated thanks
