Hi Riaan. My name is***** the engine stay running longer if you raise the RPMS up to 1500 or more?

Have you tried pumping the primer bulb over and over and over to see if it will stay running longer?

Customer: replied 1 year ago.
No and yes.

And does the engine stay running longer if you pump the primer bulb?

When did this problem start? When did the engine last run correctly? How old is the fuel?

Customer: replied 1 year ago.
I cleaned the carb, new spark plugs, tried another bulb, changed the fuel,but I think it's a fuel problem.
The motor is not getting a constant fuel supply.

When the engine is running, and when you pump that bulb over and over. Can you actually feel fuel flow through the bulb and into the engine? Is the bulb sucking flat at all, or having a hard time reinflating?
