See above for starting instructions.
As for flooding, yes.
Per instructions; If cold, use full choke. If warm, use mid choke setting. Be careful not to confuse throttle speed select with choke. Always pump primer several times regardless.

It sounds like the carb. float is set to high and /or the needle and seat has some dirt in it allowing to much fuel inside the carb.. This will allow to much fuel into the engine.It seems the carb could use a rebuild and dont forget to replace your fuel filter.I hope this helps.
SOURCE: flooding
put choke to half position NO throttle turn key works every time
.If its flooded full throttle NO Choke keep winding till it starts .

Check to see if you have spark. Put a plug in the cap and touch the cylinder , kick it over to see if the plug is sparking. I kick mine 2 or 3 times to prime the cylinder holding decompression lever in. If it pops on full choke but does not start I go to half choke. If it does not start after 3 or 4 kicks , then I turn off the choke and kick it over 5 or 6 times with the decompression lever pulled to clear it. Then I will kick with no choke or half choke. Honda's are notorious for being cold blooded so when it starts let it warm up and do not be afraid to drive a short distance on half choke till the motor warms up a little.
When the machine is hard to start after sitting I usually start by removing the carburetor and shooting carburetor cleaner through the jets and passageways.I have always found my 96 xr400 to be a dependable starter with fresh gas and a clean carburetor. If it is flooded use the decompression lever to clear the cylinder.

Same problem, runs fine with choke on, but when i touch the throttle it bogs out, sounds like its not getting any fuel. I cleaned out the carb and used fresh gas, but the problem persists. I'm going to try cleaning the air filter and getting a new plug. If thats not it it could be eletrical.

It is possible that it may be having trouble if you have some bad gas but I would be more inclined to check the float to make sure it is not hanging up and allowing to much gas to get to engine. I would adjust idle and fuel mix screw all the way shut and then start opening them up about 1/4 turn at a time and try to start and run between adjustments.Only try to start it once or twice in between adjustments to avoid flooding. If you can get it to run good then turn screws one more time or until engine starts missing a little then slowly close until it runs smoothly.Hope this helps you. Thank you.
