Hello I have a 1999 Honda 300 4w/drive and I just replaced the Oem carburetor with a aftermarket carburetor after installing the carb on the bike it started great and idled like new one but when I shifted into first gear and tried to move forward it died, I shifted back In neutral and the wheeler started easy again I let it set there to see if maybe it needed to warm up but when I shifted into first and tried accelerating it died again, I am not a use to working on it and would appreciate any advise thanks
