Should I turn my choke "OFF" (down)?, because the engine works fine when it is in up position ("ON"?). but the third time i started it, I turned the choke off (down), and that was the time the engine have an issue. It's winter right now here and the weather cools down a bit like 19 to 17 deg. at night (the time i tested the kit). I used the stock jet, I don't know what is the size of it.
And before I forgot I am using a 16:1 with my fuel/oil ratio (breaking In). When I say the engine was fine (the time the engine has no issue), its running perfectly with a good coordination with my throttle (up=fast, release=slow), but it dies when I try to slow down, while gradually squeezing the throttle and stop. I heard that, there is also a reach/lean effect with the engine from the fuel/oil ratio, do you think that somehow an issue? do I have to go to 24:1 or something?.
