2007 TRX450 dies

I have 2007 TRX 450 ER. It will start and idle just fine as soon as you put it in gear and try and give it gas it sputters and dies. I had the engine rebuilt last year and the valves were adjusted.

Does anyone have any thoughts as to why it dies when you give it gas?

Have you drained the gas out of the carb? If it sat for a long time with gas in it the carb s probably gunked up and needs cleaning.

To me it sounds like it could be either a Stuck Accelerator Pump Diaphragm (Most Likely) or a clogged Accelerator Pump Nozzle. Maybe even a blown out Diaphragm... I've even seen where when a quad sits for a while with gasoline in it and water gets into the fuel and then when it gets into the Accelerator pump it blows out the diaphragm.
