So today i was riding and i saw some spooge on my muffler so i wiped it off and set the air screw back to stock settings but now.. When i tried riding it.. It bogs when i try to rev it like passed 1/8 throttle. Should i richen the mixture and screw the air screw in more or what? I dont get any more spooge so i guess thats good and when it was making spooge it was also really hard to start it.. Would take like 10 times and then would start easier after i got it running... Im riding a rm85
