GZ250 wont start
 

Let me start by saying I failed to drain the fuel last fall =( Started a couple times this spring to make sure battery was good etc. Exhaust was a little smokey. Started it last week and brought it down to driveway and changed oil and oil filter. Started it again, topped off oil once it circulated. Went for a ride and it stalled in under a mile. Got it back home started it once again, was choppy but ran a few minutes then stalled. Cant get it started again.

I attached 2 pictures one from the top after removing seat and cargo contained. You can see the hose coming from the carb that vents to under the seat. Also a side view from the right showing the hose coming out of the side of the carb. Slightly bigger then the other hoses coming out. I think this is a vent hose?????

When I try to start the bike now gas come dripping (rather quickly) from that vent hose and it wont start. I suspect the carb is gunked up by old gas??? Is that reasonable or should I be looking for something else. I am only slightly mechanically inclined so not sure if I want to try to clean it myself if that is even the problem. Any help/suggestions would be awesome! Thanks!!

Yes your carb is flooding.Also check your crankcase for gas in the oil. :)

happy happy
 

Does not seem to be gas int he oil. Any tutorials on how to clean the carb? Preferably with some pictures!

Pickup Coil maybe bad, have similar issue year ago, replaced with unknown moped parts which is just looks a like.
