okay my bike has sat for about a month and a half. i try and start it and it acts like it is going to start but no go. hell i even have a flame coming from my tail pipe. yes i am getting fuel and apperantly yes i am getting a spark(the flame). it is a 99 honda f4 and yes it is carbed. and yes i have rebuilt them and cleaned them out about a year ago.
gas doesn't smell old and still burns the living shit out of your eyes when it gets in it.don't ask...

battery is not weak nor is it old. i even had it hooked up to a charger so i wouldn't run it down while tring to start the bike.
