HARD AS HELL TO START

[DeadLastRacing]

For some reason my warrior has an extremely tough time starting when it wants to be stubborn, especially if I need it to start, like in situations such as mid-way through a race or in the middle of the woods at the bottom of a valley, you catch my drift. It will start fine if its cold as long as I choke it about half way and give it some random gas. then it will run fine. put about an hour or so on it and kill it then try and start it, either it will immediately start right back up or noting but my starter working its ass off. What gives? I check my valve clearance and its perfect, wiring seams perfect also. Two things that concern me are that sometimes the idle will get real wacky and the idle screw seams to get me nowhere, given that this is only sometimes. Is there something getting stuck in the carb? Also the spark plug gets black black after a long set of me trying to electric start it. I hope this all in not to confusing but any input will be a great help thanks.

I have the exact same problem. It'll start fine cold, but once its been run, forget it. And my plug is also drenched in fuel after only a short time of it being off. I have good spark, and good compression so it should hopefully be a fuel issue where once it warms up its getting way to much fuel when its off and no longer will start.. Next time I get home I'm tearing the carb apart and seeing where that gets me.

Sounds like your idle circuit is too rich. First, pull out the fuel screw and make sure that it's not broken and the o-ring is not missing. Then install it, and back it out 2 - 1/2 turns from all the way in. I'd also look for air leaks if you already didn't, that can cause a random idle problem.
