What would happen if there was a hole in a accelerator pump diaphragm? What would it cause the motor to do? thanks

Stumble on acceleration and leak gas around the accelerator pump rod.

It'd be a waste of time and money, probably; it's a '99 YZ400. Your best possible bet would be to shop eBay for a used carb from an '05 or later YZ450. It's a virtual bolt-on, and a huge upgrade. Be sure to get as much of the hot start assembly with it as you can. Should be around $200.
