Hi everybody I've got a little bit of a weird one here. This engine starts idles and will putt at 3 miles per hour no problem, soon as I try to crank her up it just bogs and has a intermittent surge in revs every four to five seconds. Tank is clean new bald just replaced, carbs are spotless. I pulled the fuel lines off both carbs and turn the engine over it appears like there's plenty of gas coming out. While it's bogging pumping the bulb has no effect. Strong blue spark at both plugs. It's got the vro fuel pump that's been modified for premix. I'm scratching my head gentleman I'd love some advice. Thank you.
