Float is sticking is why it's puking gas into the air filter and crankcase... Mine has done that a couple times a few years ago...It's usually just some junk in the tank made it to the needle and seat where the fuel comes in the carb and got stuck in there not allowing it to close.....Very easy to fix....Get a piece of wood (2x4 a foot long) and a hammer...Put one end of the 2x4 against the carb and then firmly tap the other end with the hammer 2 or 3 times...Don't try to kill it, just a few firm taps.. That's usually enough to dislodge whatever is in there that has it hung open without tearing the carb apart....Worked for me both times and like I said, it hasn't happened again and this was back around 2011 I think...
Yeah I'm getting ready to tear it apart take a look I think this want to be mechanic out of reputable shop was beyond his knowledge.
Supposedly did the pair mod when he put the 49 State carburetor on it after being rebuilt I had the tank cleaned and a new petcock put in if I shop that does gas tanks.
I think he didn't disconnect all the emissions and it's putting back pressure into the pair valves.
Not knowing what he did is the reason why I was looking for a mechanic I'll figure it out I hope.
Sure is sad that Honda quit making that carb.
Will not even support an owner when you give him a VIN and it says 50 state and you're asking for a 49 state diagram
