I have replaced the fuel lines and installed a new carby kit and spark plug (I was at the shop anyway). It is still not running all that well (it ran for about half a tank of fuel and then stalled). There is always an air bubble in the primer bulb. I'm out of ideas!
Anyone?
If you don't have a filter in the tank you will have problems all the time.
Below is a parts list of the tank, fuel lines & filter.
