Really flooded 250

My "new" 84-WR250 rode 200 plus miles from were I bought it, home with the gas on-nice.. I know better but I had a student of mine that was going to Boise for the weekend pick it up for me. Checked it over and gave it a few kicks-nothing. Pulled plug-really wet, new plug really wet, has good spark. Get piston in right spot and use blow nozzle thru plug hole and blow air for awile out exhaust. Still wets plug. Drill crankcase and get a aerasol cap full of black gas. Tap hole and insert 1/8" NPT plug. Any other ideas before I start kicking and cleaning plugs again? Thanks in advance Scott

air filter...take off rear part of exh pipe..maybe choked ?

Found the cause of the extreme flooding, float level way too high. Pulled carb and found float arm level without compressing needle spring causing way too high of float level. This would also explain the very lean jetting in it, suppose to have 450 main, it has 360, suppose to have 45 pilot, it has 32 and needle was at lowest clip- max. needle into jet. Someone was trying to compensate for the high float level with lean jetting. Wonder what other "contingent damage" I will find. Thought about putting the bike on its back but my back says no. I ruptured a disc in my lower back in 2001, they also found the one above/below herniated bad. They wanted to fuse my five lower back vertabreas- I said no, I was only 35 and would wait for a better fix. With that I can only lift about 25-30lbs but do what I can do, I ride very conservatively, bike goes down I have to have help getting it back up but I have fun anyway. I used to do alot of drag/street rod chassis fab in the garage but back doesn't stand up to that. I enjoy working on the bikes better now, only need help with the engine removal/install.

It runs!!! Actually fired up first kick. Now have some jetting to do and it will be ready to ride. Vibrates a whole lot less than my 500's. Not much riding around here in the winter so that will give me time to tinker on it. Thanks for the help.

Thats me.

I give?

Had this SAME thing happen to my 250 the other day. It has been in the shed for about 2 weeks or so without being run and I got it out and It wouldnt start. I was getting good spark and everything. Well it turns out i was still wetting the plugs even with the gas turned off and the carb drained. The cylinder had gas trapped in it somehow. I took it out in the grass and laid it over and let the gas drain out the top.

I brought her back in the garage and put a new plug in it, and it wetted it too. I took an air blow gun and shot some air down the plug hole and when i released the trigger i heard sloshing. I took the exhuast manifold off the front with the 4 allen head bolts and took the whole expansion pipe and glasspack/flame arrester out and ended up pouring about a CUP of gas out of it. Put that back and it fired 2nd kick on choke.

What do I need to look at to make sure the floats dont do that again?

I always run my bike for awile before I shut it down with the gas off. My uncle had a 501 Maico and taught me this, before starting turn gas on for a few seconds then turn off. Choke and start then turn gas back on. This keeps floats from bouncing when kicking bike to start. Gravity fed carb has alot of pressure on needle/seat from gas above. My 500 always floods easy so I have a drain in the crankcase.
