OK I did order 10 feet of fuel hose so I can replace all of the fuel lines and the vacuum hoses. Just for giggles I snipped the ends of all of the vacuum hoses (some had small cracks) and now it runs much better. I don't want to jinx myself but I'll report back once the lines are replaced.

I haven't changed the location of the fuel pump. That's where it was when I bought it. Since fuel outlet is on the top of the tank there's got to be a pick up tube.

Also I should say I'm getting horrible gas mileage. I used to get around 60-65. Now it's down to 40.

Engine pics. I'm going to warm it up and upload some video of the problem.   |

Too much fuel?

Thanks for the quick response guys. It's a Znen 150t-e. Since the fuel tank is below the carb I do have a pump, not a vacuum actuated petcock. Yes .005" not mm, my mistake. It's a little clattery but much easier to start than when the valves were set at .003" and much better for my riding style which uses two throttle settings, fully open or fully closed.
I'll post some photos when I get to work. I'm trying to rule out a vacuum leak so I just ordered 10' of clear fuel line (neon green!) so I'll be able to see if fuel is backing up into the vacuum lines. My intake manifold isn't cracked but the O ring looks suspect. I had the idle set a little high because of the bogging issue.

Hi there, it's my first time posting on the forum.
I've got a very weird problem. It seems like too much fuel is getting to my carb. I installed a new carb last month but had the same problem with the old one. If I go over a bump the engine bogs so I have to rev it a bit to keep it going. It runs fine at higher speeds but if I rapidly let off the throttle around 25mph, it bogs. I put it on the center stand to test my theory. If I rock it so the front wheel hits the engine bogs every time. If I pinch off the vacuum hose going to the fuel pump and rock it, it never dies. If I stop pinching it and continue rocking the bike it dies within 5 seconds. I disassembled the float bowl and the float isn't stuck. Idle mixture is one and a half turns out. I recently changed out the fuel filter to one of the glass ones, put in a new spark and adjusted the valves to .005mm.
