Pinesol does wonders as well. I did that the last time to mine and it made a huge a difference.Did you soak the main unit over night? i just posted in my previous thread that i was having carb issues with my 96 lakota 300. last night i disassembled it about 8pm and went to walmart and bought 3 cans of gumout carb and choke cleaner. I washed out a plastic trash can real good and layed the main unit on its side and began to spray all 3 cans into the can I didnt have to soak the jets because i just a brand new rebuild kit. so i got up this morning and took it out of the cleaner and blasted air thru all the ports multiple times reassembled and ran like a top had the dang thing tore apart 9x but didnt soak the main unit over night. It could be your starter jet port or the pilot jet port if you havnt soaked it for at least 8-10 hours i would really suggest doing it. but make sure when you get it back out get some white lithium grease or something other then wd40 and make sure to spray the flap valve bearings really good. I also soaked the throttle spring because the carb cleaner will dissipate all the grease in the bearings from soaking it.
