Default Help!! Low power on and can't figure out why

Hi all,

So I picked up a kandi 150 gka-2. Here is a stock pic:



It was smoking real bad when I got it and I put a new big bore kit to 155cc. This is the one I got: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

This was my first time working on one of these and I got it running. I put a 120 jet in the carb. My problem is low power. Going up a mild hill on the street and I can only go about 13 mph.
I had an intake leak and ordered a new one. This one here: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

What else can I check? How do I diagnose this from here? Could I have the timing wrong? I double checked the valves and set them at .005. I did a compression test and got 185-190 psi.

I took the carb apart again and checked all the jet passageways. appears to be getting fuel - when I take the line off the carb, fuel dumps out....

Oh - I also went to a yellow spring and 10g roller weights (did this last year so going on memory on the roller weights! 99%)

The spring I bought: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Thanks!
Joe
