6 years?!
I'd tell you to clean it again if it was 6 months. It'll be yucky in there.

 

When the backyard mechanic (small engines) guy sprayed it and blew it out, it didn't fix anything (still sputtered). So I'm thinking why clean it again? Even I myself took it apart a couple times, and soaked it in cleaner overnight, one time, still nothing. Actually, I did see what looked like a very good carb that matched all my ports or what have you, on amazon and it looked like a mikuni, for just $72. I guess maybe, I underestimated the web. Because a new one from my dealer is $600. I'll let you know if I ever try it, because the bike still gets me from point A to B.
