I have a 2000 trailblazer (250 2-stroke)........is there any settings (lean-mid-rich) that I should be aware of. I here the scrambler 400 has this setting but couldn't find one on the TB ??? are there any other ways to change this. How do you tell if the pump is bad and running in full rich mode, besides fouled plugs.....would mixing oils have anything to do with this, I did add aome gn2 or yamalube (cant remember have both) once when I was running low, probably 8 onces max with 10+ onces polaris blue already in there. Maybe I'll drain it all out and start with some fresh blue stuff from polaris ( I had a gallon given to me !!! )

I like the polaris gold synthetic oil. There is an adjuster on the cable that goes to the oil pump, and it needs to start opening the oil pump at exactly the same time the throttle slide starts to open.
