Need some advise on a new install and new engine. Starts fine and runs great, but when I go over a bump, the engine sputters and loses power. Full throttle does nothing. It usually stalls out. If I go over another bump, it comes back to full power with no sputtering.
Thank you in advance for your assistance.

Gas cap vent issue, float sticking in carb not letting bowl fill correctly, fuel line issue. Just guesses, does it die immediately? Could be electrical as in kill sw short or bad spark plug wire issue. Shorting to ground. I'd be looking on the fuel side if it were me.

No it's still the same. I'm sure it's the float that's sticking, as every time I hit a bump it stalls out, then when I hit another bump, it's back to normal. It is the stock carburetor, btw. Just ordered an NT carburetor and intake adapter to hopefully solve this problem. It is a new engine, so everything is clean. Any suggestions would be welcome.
