i have an 03 predator that I have ownded for about a month now. every time I have started it up in the garage it has started at the press of a button. now out at my acreage it will not stay running. at first the issue was the carburetor had come out of the boot on the intake manifold but now that its back in it still won't run. When I put my hand over the back side of the carburetor, there is a strong blow back coming back from the engine, it covered my hand in gas. I cannot tell whether it is the intake valves that are stuck open causing gas to come back into the intake and through the carb. or whether my carb needs cleaning. any info or help would be awesome. thanks.
