Ok so this is how it goes I'm running a SD stinger with some cheap craftsman 2 stroke mix at 16:1 the manufactures recommended break in mix and the thing starts and runs 
. but it will race then stall if I let it idle at a what seems like a normal idling speed while clutch is engaged. Also the exhaust is very dirty (ex its blue and nasty) and it is constantly like this while dripping oil. I took the plug out and it was covered with oil. My question is could I safely use a Leaner mix and would that solve the problems encountered. If not what would solve these problems.
If so what ratio would be good and/or possibly different oil to use as it is still in early break in and i don't want to mess this up.
