today i took it for a short ride and was doing about 50mph then it bogged and stalled. i drove it home and it was idling good then it suddenly stalled again and would only start and run with the choke on, whats this sound like?

 

it won't stay running for 2 secpnds now where is the fuel filter located?

 

Sounds like... you probably should listen to OPT. Take the carb off, and clean it. With the ethanol infused fuel that has been forced on us, we have to constantly clean the carbs. Once clean you should try to find some filling stations that sell ethanol-free gasoline. The ethanol gas creates havoc on fuel lines, fuel filters, and carbs.

 

ok i pulled the 3 lines off my fuel pump and the top line pissed gas out all over, the middle one just dripped and the bottom of the fuel pump had no fuel coming out, is my fuel pump done?

 

Check your air filter connection to the engine. I had the same problem, it turned out my air filter came out from the engine. I dunno why, but it took away power.

EDIT:

Oh.. It's not feeding fuel. Clean your carb as others stated.

 

Also, i hope you turned off the gas flow. There's a switch on the left side that lets you control gas flow.
