I'm not sure what you guys have run into when doing the carb mods, but after drilling out the plug in mine, I noticed the screw was at least 3 turns out. Soooo, I pulled the spark plug and found it fouled. Too rich? I thought these things came too lean from the factory. Anyone else have this?....and if so, did you notice any other oddities? Just got back into dirt riding after 35 years, so I'm kind of new to this, but I'm not new to engines...or the planet. I was expecting something else after reading all your very informative comments over the past 7 months. Thanks for those, by the way. I'm a huge fan of this forum, but can't post a lot because I take care of my 2 year old. One reason I bought a 230 instead of gasser. Thanks in advance.
