Hello everyone,

I have a OS 52 4 stroke and I am having a problem, maybe someone can help me out with it.

here is what it is doing .....

it is cutting out at half throttle. I can run it at full open but it seems like it is not running at full power. Then when I start to throttle down it is
acting like it is at idle when I am only at half throttle then dies.
here is what I have done so far ...I closed the needle valve then opened it 2 1/2 turns and I also reset the low end per instructions and still it is doing the same thing. I am at a loss what to do next.

thanks in advance,
