Have a 13B with the turbo II drivetrain I premix nonsythetic oil when I fill up my tank And recently I've been having a rough idle (below 900-0 and after a few minutes of idle it will shut off.) Driving is normal It's also been rough starting, it'll turn over and try, but won't start. After a few tries it will, but it blows a lot of smoke (blue) I'm wondering if it's a fuel pump issue. Any suggestions before I start tearing **** apart?

 

Does the engine still have the OMP working along with you Premixing?
and what ratio of 2 stroke to gas are you using?

 

No my OMP wasn't working when I got it, but it also wasn't havin the idle issue then. I use half a quart of oil per tank of gas in.
